Taking a CRA (Concrete-Representative-Abstract) approach can help students to understand and generate related facts and addition and subtraction fact families. This post will outline 5 strategies that you can use to have your students practice addition and subtraction fact families.<br /><br /><h3 style="text-align: center;">5 Strategies for Teaching Addition and Subtraction Fact Families </h3><h3 style="text-align: center;"><a href="https://4.bp.blogspot.com/-o4bixDyA7Zs/XES38_6TtGI/AAAAAAAAM9Y/CW6KQv_WrrAJxi3GXAQIrKbjYoFOYFdyACLcBGAs/s1600/Slide6.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="400" src="https://4.bp.blogspot.com/-o4bixDyA7Zs/XES38_6TtGI/AAAAAAAAM9Y/CW6KQv_WrrAJxi3GXAQIrKbjYoFOYFdyACLcBGAs/s400/Slide6.JPG" width="300" /></a></h3><h4 style="text-align: center;">Strategy #1</h4>Allow students to use a material such as linking cubes that they can physically put together and take apart to generate the 4 related facts.<br /><br />In this example I added pictures of turtles and turtle shells to the blocks so that there is a context around the number as well.<br /><br />While students are using the hands on materials, I am also asking them to put their numbers into a number bond. This will help to take away the hands on scaffold further down the line!<br /><br /><h4 style="text-align: center;">Strategy #2</h4><div><a href="https://3.bp.blogspot.com/-f0T5LP8tdtc/XES385Of4dI/AAAAAAAAM9s/wzeyVIPS7TwJ2_GqYsFjC_yn9zsD3HUrgCEwYBhgL/s1600/Slide7.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="400" src="https://3.bp.blogspot.com/-f0T5LP8tdtc/XES385Of4dI/AAAAAAAAM9s/wzeyVIPS7TwJ2_GqYsFjC_yn9zsD3HUrgCEwYBhgL/s400/Slide7.JPG" width="300" /></a>A material such as red and yellow disks is another concrete tool that can be useful for your students. The difference between the linking cubes with pictures and red and yellow disks is that the disks lack a story context making them a bit trickier to work with for students. </div><div><br /></div><div>Even if you opt to use linking cubes without the attached pictures, it is useful to use another concrete tool in another lesson so that students can begin to generalize what they are noticing about putting parts together and taking them apart to generate related equations.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://4.bp.blogspot.com/-GWkw7OGUbiA/XES39Msgg_I/AAAAAAAAM90/atG530_wVpgHgmgBq_IAM9y9asVBHeBeACEwYBhgL/s1600/Slide8.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="400" src="https://4.bp.blogspot.com/-GWkw7OGUbiA/XES39Msgg_I/AAAAAAAAM90/atG530_wVpgHgmgBq_IAM9y9asVBHeBeACEwYBhgL/s400/Slide8.JPG" width="300" /></a></div><h4 style="text-align: center;"><span style="text-align: center;">Strategy #3</span></h4></div><div>Taking a step away from concrete materials, dice are a great representative tool. By using dice students can still see both parts that they are manipulating. They can still push them together and pull them apart to simulate the action associated with addition and subtraction number sentences, however, they are no longer manipulating each individual unit. </div><div><br />In this case I did not pair the activity with a number bond in an effort to begin to decrease a student's reliance on that tool at all times to generate related equations but you certainly could! </div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-K-c6YdKprNE/XES39ZSy75I/AAAAAAAAM9w/__0YjcMWEY8qddZp2QHNPn0W0Y_9CBfrwCEwYBhgL/s1600/Slide9.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="400" src="https://2.bp.blogspot.com/-K-c6YdKprNE/XES39ZSy75I/AAAAAAAAM9w/__0YjcMWEY8qddZp2QHNPn0W0Y_9CBfrwCEwYBhgL/s400/Slide9.JPG" width="300" /></a></div><h4 style="text-align: center;">Strategy #4 </h4><div style="text-align: center;"><span style="font-weight: normal;">In strategy number 4 I am taking away all visual cues aside from a number bond. At this point students are working with numbers in a number bond but they don't have any tool to manipulate the parts that are being put together and taken apart. </span></div><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-lSvM1hzxhqg/XES380USNEI/AAAAAAAAM90/4CHip_wglt07KaeUjkvvHw2T1jKwvNNugCEwYBhgL/s1600/Slide10.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="400" src="https://3.bp.blogspot.com/-lSvM1hzxhqg/XES380USNEI/AAAAAAAAM90/4CHip_wglt07KaeUjkvvHw2T1jKwvNNugCEwYBhgL/s400/Slide10.JPG" width="300" /></a></div><h4 style="text-align: center;">Strategy #5 </h4><div>Strategy number 5 is not so much of a strategy. At this point, if students have worked away from needing a hands on tool or visualization, they should be able to independently generate related addition and subtraction word problems. </div><div><br /></div><div>In this example I have students play a game where each student comes up with a number 1-10 and writes that number in their candy bag.

Meet your students and their energy with a fun and novel activity that keeps them learning. Try one of these 3 Valentine's Day math crafts this upcoming holiday season!<br /><br /><h4 style="text-align: center;">Valentine's Day Love Bug Math Craft</h4><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-II6fRLVPDp4/XDd8oekVL4I/AAAAAAAAMj8/mNM4QjTOZ5kg3wZEEs08C9aD7x25_po2QCLcBGAs/s1600/2Craft.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1119" data-original-width="1138" height="314" src="https://1.bp.blogspot.com/-II6fRLVPDp4/XDd8oekVL4I/AAAAAAAAMj8/mNM4QjTOZ5kg3wZEEs08C9aD7x25_po2QCLcBGAs/s320/2Craft.png" width="320" /></a></div><div>To do this activity with your students, you will need to provide your students with bug bodies. Accordion fold strips of paper for arms and legs and your students are ready to create this cute craft! Allow your students to choose a 3-digit number and ask them to show different representations of their number on the bug's body, arms and legs. If you want to add space for even more representations, you can also add hands and feet to your Love Bug. Representations can include: </div><div><ul><li>Unit Form</li><li>Word Form</li><li>Standard Form</li><li>Expanded Form</li><li>Place Value Drawing</li><li>Show the Number in Money</li><li>Even or Odd</li><li>Equation</li><li>Etc! </li></ul><h4 style="text-align: center;"> Fact Family Valentine's Day Math Craft</h4></div><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-lgeNcw2Ycms/XDd8oSsfsZI/AAAAAAAAMkM/V6mpngFn--YpOpno4z5J6sGvWk9CfetLgCEwYBhgL/s1600/3Craft.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="1097" data-original-width="1210" height="290" src="https://3.bp.blogspot.com/-lgeNcw2Ycms/XDd8oSsfsZI/AAAAAAAAMkM/V6mpngFn--YpOpno4z5J6sGvWk9CfetLgCEwYBhgL/s320/3Craft.png" width="320" /></a></div><div>This activity is perfect for a kindergarten or first grade class. Give your students 2 heart templates. On one template, ask your students to create a number bond. On the second template, ask your students to write 4 (or 8!) related number sentences. I HIGHLY recommend allowing your students to use linking cubes in two colors to help to generate the related number sentences. For example, a 4,5,9 number bond can be explored with 4 red cubes and 5 blue cubes. As students put the cubes together and take the cubes apart they can list the related facts. </div><div><br /></div><h4 style="text-align: center;">Fraction Chocolate Box Valentine's Day Activity </h4><div><a href="https://1.bp.blogspot.com/-hDgVavwUp34/XDd8omLkgKI/AAAAAAAAMkI/7X8NSQ0LF9UQX4Ths0ZEagtBl4LD41HfgCEwYBhgL/s1600/1Craft.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1091" data-original-width="1080" height="320" src="https://1.bp.blogspot.com/-hDgVavwUp34/XDd8omLkgKI/AAAAAAAAMkI/7X8NSQ0LF9UQX4Ths0ZEagtBl4LD41HfgCEwYBhgL/s320/1Craft.png" width="316" /></a>Third or Fourth grade students would benefit from this Valentine's Day activity. Give your students a chocolate box template with a set number of chocolates. Ask your students to "fill" the chocolate box with a small selection of chocolates they design themselves. I like having 8 chocolates and asking the students to fill the box with 3 types of chocolates they design themselves. Eight is a nice number because it plays will with equivalent fractions (1/2 and 1/4) so there is room for students to explore. Next, ask your students to describe their chocolate box in terms of fractions, compare the fraction of different types of chocolates and look for equivalent fractions. </div><div><br /></div><div>If you are looking for a QUICK way to introduce any of these activities to your students, I have created templates and planning pages. A quick "print and go" will have your students engaged and ready to go! </div><div><br /></div><div><hr /><h4>Related Resources:</h4></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.teacherspayteachers.com/Product/Valentines-Day-Fact-Families-Craft-4293470?aref=tv3kgs2k" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://4.bp.blogspot.com/-hhsPynJUJeo/XDd-kQzJCkI/AAAAAAAAMkY/JlBqFaxvDLUrfaiqaVF_0mGGa9cm7n0PQCLcBGAs/s200/Cover%2BUpdate%2B3.jpg" width="200" /></a> <a href="https://www.teacherspayteachers.com/Product/Valentine-s-Day-Fraction-Project-4299381?ref=feed/sellers_updates_product&aref=iaskhows" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://1.bp.blogspot.com/-6C_lWz3-5GQ/XDd-irNnKyI/AAAAAAAAMkU/QfMuOhVJXR0bjepdX9XwfjJCrkNg7d3QgCLcBGAs/s200/Cover%2BUpdate%2B3.jpg" width="200" /></a> <a href="https://www.teacherspayteachers.com/Product/Place-Value-Valentines-Day-Math-Craft-4292039?aref=tv3kgs2k" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://2.bp.blogspot.com/-dbxniZETBQ4/XDd-p6elMOI/AAAAAAAAMkc/ZFL58W5EZMEbMTku3jug1tbyZOMQ2PYMQCLcBGAs/s200/Cover%2BUpdate%2B3.jpg" width="200" /></a></div><br /><br /><div><br /></div><div style="text-align: center;"><img class="nopin" height="50" src="https://1.bp.blogspot.com/-iF93yAWRsQs/WUuigPmhuCI/AAAAAAAAL_g/pyHwSsJFEZ8Pvq1facQ-YnT8EoJmfF0YgCLcBGAs/s1600/signoff.png" width="150" /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-35228429767508090302019-01-05T13:23:00.004-05:002019-01-05T13:33:31.104-05:00Word Problem Strategies for All Students <div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-sBPRqtFZ_ts/XDD4bEHTz7I/AAAAAAAAMbI/i__aWKkWhfYqcVV5R8VoY_iqOuKCYgj_ACLcBGAs/s1600/Word%2BProblem%2BStrategies%2B.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="800" height="320" src="https://1.bp.blogspot.com/-sBPRqtFZ_ts/XDD4bEHTz7I/AAAAAAAAMbI/i__aWKkWhfYqcVV5R8VoY_iqOuKCYgj_ACLcBGAs/s320/Word%2BProblem%2BStrategies%2B.png" width="213" /></a></div>You have probably received mixed messages about teaching your students to understand word problems. Should you use tape diagrams or number bonds? Should your students draw pictures or should you tell them to only draw circles? Should you teach the arithmetic before asking students to apply that math to a word problem or should you use a word problem to teach arithmetic? Should you have your students follow an acronym or list of steps to solve word problems or should they learn organically? The list of "suggestions" is long and complicated and yet solving word problems is still a top the list of difficult math topics to teach.<br /><b><i><br /></i></b>For so many of our students, difficulty with word problems is less about the math and more about a lack of understanding around what is happening in the scenario. This is an issue of comprehension and when we are talking about how to help our students understand abstract concepts we <i>know </i>that the most effective approach is to think <a href="https://www.k5mathspot.com/2015/12/when-they-still-dont-get-it.html" target="_blank">C-R-A (Concrete, Representational, Abstract)</a>. <a href="https://1.bp.blogspot.com/-P__dLFCzFkI/XDDwJYtWCxI/AAAAAAAAMaw/ePHMVStT0SsuMNgHGR_DZ-INU1_cUHxmwCLcBGAs/s1600/Valentines%2BDay%2BWord%2BProblem.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em; text-align: center;"><img border="0" data-original-height="843" data-original-width="1125" height="478" src="https://1.bp.blogspot.com/-P__dLFCzFkI/XDDwJYtWCxI/AAAAAAAAMaw/ePHMVStT0SsuMNgHGR_DZ-INU1_cUHxmwCLcBGAs/s640/Valentines%2BDay%2BWord%2BProblem.png" width="640" /></a><br />C-R-A is a pathway to understanding abstract concepts beginning with the concrete. So why don't we <i>regularly </i>do that with word problems? This is an easy fix! Take a look at the problem above. This may be a difficult problem for many first grade students to solve but it is made much more attainable if we think C-R-A. Below is a continuum of C-R-A informed strategies you can use to meet each of your students where they are to solve problems.<br /><br /><ol><li>Give students a manipulative such as flower shaped mini erasers. Ask them if they can use the erasers to build the story. <i>You won't see students who are "plugging and chugging" when you ask them to build the story with a relevant manipulative. </i></li><li>Use a concrete material such as blocks to represent the flowers in the story problem. This is a bit more difficult than flower erasers because your students need to understand that each block equals a flower. </li><li>Ask students to draw a picture of flowers that matches the story. YES. I said to have your students draw flowers. Is this the ultimate end goal for our students? Drawing actual pictures of what is going on in the word problem? No way! But for some of your students, they will need their picture to match the story problem in a way that drawing circles just doesn't achieve. </li><li>Ask students to draw a "math picture" of the problem using circles or another simple shape to represent the items in the story problem. </li><li>Ask your students to use a math model such as a tape diagram, part part whole drawing or number bond. </li><li>Ask your students to write an equation that matches their model. </li></ol><div>As always with the C-R-A strategy, don't necessarily travel in a linear "one after the other" pathway through these 6 steps. You want to, whenever possible, link the steps together. For example, present a student with a word problem, ask them to represent the problem with flower erasers and, when they are successful, ask them if they can draw a number bond that matches what they just did with the flower erasers. When they are successful with this step, ask your students if they can write an equation that matches their number bond. </div><div><br /></div><div>I would love to hear from <b>you</b>.

One reason why this is such a difficult skill to teach or to learn for some of our kids is because not only are they learning new content, there is also a whole slew of new vocabulary that comes with it! </span><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-s3oIHSubfk4/XBKTpHKkNLI/AAAAAAAAL60/2AsHpgFL1sgeHz_D1yH9WFTU92SIoV39ACEwYBhgL/s1600/Slide3.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="320" src="https://3.bp.blogspot.com/-s3oIHSubfk4/XBKTpHKkNLI/AAAAAAAAL60/2AsHpgFL1sgeHz_D1yH9WFTU92SIoV39ACEwYBhgL/s320/Slide3.JPG" width="240" /></a></div><span style="font-family: inherit;">Much of learning to name fractions in third grade is an exercise in understanding and applying new vocabulary terms. In second grade when students were laying the foundation for fraction work students used words such as half, quarter and whole. Teachers may have talked about parts or pieces but they most likely weren't using words such as numerator and denominator at that point in time. </span><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-GGDPjZPhcw0/XBKTpBchS8I/AAAAAAAAL68/s_C0-mUjJRwXEZ2vWYyYEy0Aa5EzbsQ4QCEwYBhgL/s1600/Slide5.JPG" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="320" src="https://3.bp.blogspot.com/-GGDPjZPhcw0/XBKTpBchS8I/AAAAAAAAL68/s_C0-mUjJRwXEZ2vWYyYEy0Aa5EzbsQ4QCEwYBhgL/s320/Slide5.JPG" width="240" /></a></div><span style="font-family: inherit;">It can be so helpful at the beginning of a new unit on fractions to be sure to teach and practice vocabulary in a systematic way to help prevent misconceptions and misunderstandings! Let's look at the word denominator as an example. Understanding the denominator of a fraction is not difficult. If you look at a whole broken into 6 pieces you know you are working with sixths and the denominator of the fraction is 6. This is really just an exercise in counting! There is no earth-shattering, difficult to learn math here. But, the word </span><i style="font-family: inherit;">denominator</i><span style="font-family: inherit;"> is definitely new to our students and so they need time and room to practice the new concept of identifying and understanding the denominator while applying the vocabulary of denominator. </span><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-vEuKINJOLjQ/XBKTpeVPlTI/AAAAAAAAL7A/U9l4BH4yEQseuM-dWq5xOoF8Nf0c_lvcwCEwYBhgL/s1600/Slide7.JPG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="960" data-original-width="720" height="320" src="https://2.bp.blogspot.com/-vEuKINJOLjQ/XBKTpeVPlTI/AAAAAAAAL7A/U9l4BH4yEQseuM-dWq5xOoF8Nf0c_lvcwCEwYBhgL/s320/Slide7.JPG" width="240" /></a></div><span style="font-family: inherit;">When our students are really very comfortable with these new fraction vocabulary words they will be able to free up the mental space to think about the new understandings that come along with fractions. Hands on experiences will be more rich when our students are ready to explore and apply their understandings around these new vocabulary words. Am I saying that you </span><i style="font-family: inherit;">need</i><span style="font-family: inherit;"> to teach the vocabulary </span><i style="font-family: inherit;">before</i><span style="font-family: inherit;"> you can allow your students to explore with fractions? ABSOLUTELY NOT!! What I am advocating for is that once students have had instruction around vocabulary you are sure to give students opportunities to use their new vocabulary to describe what is happening with fractions even if the concepts themselves seem simple. </span><br /><h4>So how might this play out in the classroom? </h4></div><div style="background-color: white; overflow-wrap: break-word; user-select: text; white-space: pre-wrap;"></div><ul><li>Day 1: Your students do an activity where they are looking at pizzas that have been cut into equal pieces. You have each pizza labeled with a unit fraction describing one piece of pizza. Students are doing a notice and wonder activity around what they see in the pizzas and what they see in the labels on the pieces of pizza. </li><li>Day 2: Yesterday, your students noticed that the bottom number of the fractions match the number of pieces of pizza. You tell your students that their observation was spot on and that we have a math word for this- denominator! Next, give some explicit practice of this concept! Look at these different pictures, what would the denominator be on each of these fractions? <b>Practicing math concepts is not a bad thing. Every single math lesson you teach does not need to be a hands on discovery lesson- sometimes, after building an initial understanding you just need to practice! </b></li><li>Day 3: Your students have been working with the word denominator so you want to give them a new experience that will allow them to apply their new vocabulary word. Maybe you do an activity with a pan of brownies. You tell an elaborate story about how at first you baked these brownies to share with just 4 friends but, as more friends showed up to your party, you had to cut them into more and more equal pieces. As you work through the story, ask your students what is happening to the denominator of the fraction. Ask if they could write fractions recording the denominator as more and more friends show up. Expect your students to use this word, a lot! </li></ul><div><hr /></div><b>Related Resources: </b><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.teacherspayteachers.com/Product/Naming-Fractions-Interactive-Notebook-1130389" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="320" src="https://1.bp.blogspot.com/-B52qn4zrESI/XBKSeKRwtwI/AAAAAAAAL6U/pCqcixIUcpk6_IZwHdj8fKZ6_c3w1IsOwCLcBGAs/s320/Cover%2BUpdate%2B3.jpg" width="320" /></a></div><b>This resource is perfect for allowing your students to learn and practice new vocabulary associated with naming fractions.

By using the CRA (Concrete-Representative-Abstract) framework your students will link what they already know about <u>multiplication</u> to the <u>multiplication of fractions</u> and will be successful in no time at all!<br /><br /><h3 style="text-align: center;">Concrete Multiplying Fractions by a Whole Number</h3><div>Before you begin with fractions, anchor your students back into what it means to multiply. Give them a pile of blocks and ask them to model something super simple such as "4x3" your 5th graders should quickly and easily be able to model this problem. Ask your students about what they built and how they know it represents the equation. </div><div><br /></div><div><div style="text-align: right;"><a href="https://2.bp.blogspot.com/-rTK6gBtx1dI/W_BJMALRL8I/AAAAAAAALWE/EQ86OXbcvhsVjUdF-L03ywAligT5AhmUwCLcBGAs/s1600/sixtimesrep.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="281" data-original-width="234" height="200" src="https://2.bp.blogspot.com/-rTK6gBtx1dI/W_BJMALRL8I/AAAAAAAALWE/EQ86OXbcvhsVjUdF-L03ywAligT5AhmUwCLcBGAs/s200/sixtimesrep.jpg" width="165" /></a></div>Go ahead and get out your pattern blocks. They are the PERFECT fraction representation. Let the hexagon represent a whole and allow your students to figure out which blocks represent 1/3 (rhombus), 1/2 (trapezoid) and 1/6 (triangles). Once your students are all set with their blocks, they are ready to begin! Don't have fraction blocks handy? Fraction circles would work just as well! </div><div><br /></div><div>Ask your students "If 4 groups of 3 blocks represented 4x3, how could we represent 4 x 1/3?" Allow students to use the rhombus pattern blocks to represent 4 groups of 1/3. The beauty of using blocks is that students can put these blocks back together to see both the improper fraction and mixed number that is created when fractions are multiplied together.<br /><br />**<span style="font-size: 12.8px; text-align: center;">This PICTURE is not a concrete </span><span style="font-size: 12.8px; text-align: center;">model, but if you are creating </span><span style="font-size: 12.8px; text-align: center;">this model out of fraction tiles, </span><span style="font-size: 12.8px; text-align: center;">your students are working at the </span><span style="font-size: 12.8px; text-align: center;">concrete level! **</span></div><div><br /></div><h3 style="text-align: center;">Representative Multiplying Fractions by a Whole Number</h3><div><a href="https://2.bp.blogspot.com/-gaQXVYMUonY/W_BJM6XIvaI/AAAAAAAALWI/Q9Zzgp_4Og4lB_ElRX66mHMXJHK01pP9QCEwYBhgL/s1600/sixtimesrepeated.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="284" data-original-width="224" height="200" src="https://2.bp.blogspot.com/-gaQXVYMUonY/W_BJM6XIvaI/AAAAAAAALWI/Q9Zzgp_4Og4lB_ElRX66mHMXJHK01pP9QCEwYBhgL/s200/sixtimesrepeated.jpg" width="157" /></a>Once your students are able to model 4 x 1/3 you want them to link this understanding to a representative model such as repeated addition.

After your students have had a good deal of exposure at the concrete and representative level, give them a new equation such as 4 x 2/8 and ask your students what they *think* the product will be. You are looking for your students to make generalizations about their multiplication and fraction understandings and to be able to explain their thinking. After a student shares their thinking, ask all students to model with concrete materials or a repeated addition equation to confirm the product!<br /><br />I have created a set of playing cards that includes multiplication equations, visual models, repeated addition and the resulting products. Your students can play so many traditional card games with this deck of cards - and I have included the instructions for 5 games to get you started!

Right off the bat, I want to mention that the standard algorithm is <b><i><u>NOT</u></i></b> a part of the second grade standards! That being said, so many of the programs that we use expect that students use the algorithm and even "exposure" sticks with our students. Luckily there is a way to teach subtraction with regrouping that honors the developmental needs of second grade students.<br /><br />The C-R-A (Concrete, Representative, Abstract) approach is the way to go here! Start students with hands on materials and, at first, don't expect any notation at all in terms of the standard algorithm, and allow students to explore the crossroads of operation and place value.<br /><br /><h3 style="text-align: center;">Concrete Materials </h3><div>When choosing concrete materials for your students to use when adding or subtracting multi-digit numbers consider the difference between groupable and pre-grouped models. Base ten blocks are a common tool used to represent subtraction for early learners. There is nothing wrong with using this tool. Be aware, however that base ten blocks are a <i>pre-grouped model </i>and are not appropriate for all learners. </div><div><br /></div><div>Some of your students may have difficulty understanding why you would "trade a ten for ten ones" when using base ten blocks. Consider starting your instruction using a groupable model such as linking cubes.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-vX4v8ranmTA/W-d4m9YTt7I/AAAAAAAALOM/0TMDoalSNSMb3N-d6RDG0LWDedEQwl4_QCLcBGAs/s1600/groupable%2Bmodel.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="915" data-original-width="1600" height="366" src="https://1.bp.blogspot.com/-vX4v8ranmTA/W-d4m9YTt7I/AAAAAAAALOM/0TMDoalSNSMb3N-d6RDG0LWDedEQwl4_QCLcBGAs/s640/groupable%2Bmodel.png" width="640" /></a></div></div>You can see in the example above the strength of a groupable model. When subtracting 47 from 74, sutdents were able to break a ten into ones rather than "trading" one item for another. This is more true to what actually happens when subtracting!<br /><br /><h3 style="text-align: center;">Representative Models</h3><div>Once students understand what is happening when regrouping or unbundling in subtraction, they may be able to transition to subtracting without using a physical concrete material. One representative model that many students find success with is the place value chart. </div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-J4WTB5uFpJs/W-d5g3FD-5I/AAAAAAAALOU/sTBMBinYY1s9rh36H1hOaN32wO-hWKAtACLcBGAs/s1600/RepresentativeSubtraction.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="727" data-original-width="1125" height="412" src="https://1.bp.blogspot.com/-J4WTB5uFpJs/W-d5g3FD-5I/AAAAAAAALOU/sTBMBinYY1s9rh36H1hOaN32wO-hWKAtACLcBGAs/s640/RepresentativeSubtraction.png" width="640" /></a></div><div>An especially effective way of transitioning to a representative model is to ask students to use a concrete material and to "draw what is happening to your blocks". In the 3-digit example above, students would start by building 675 with a concrete material such as base ten blocks. Students would then draw the 6 hundreds, 7 tens and 5 ones that they have built. As they manipulate their blocks, they would also reflect these changes in their drawing as well. </div><div><br /></div><div>As with concrete materials, there are nuances in representations as well. Your students may start by showing hundreds, tens and ones as a place value drawing because they are a more direct representation of place value. As your students become more confident, they may be able to simply draw dots in each column of the place value chart to represent the number in each place value. </div><div><br /></div><h3 style="text-align: center;">Abstract</h3><div>I'll say, once again, that the standard algorithm is NOT expected in 2nd grade! That being said, programs, parents, and older brothers and sisters are all going to provide exposure to the algorithm. If you would like to introduce the algorithm in a more conceptual way, consider asking your students to "record what is happening with numbers". This can be done at either the concrete or representative stage. As students are regrouping or unbundling with blocks, they can show the changes in each place value numerically. Again, as students are using place value drawings to show unbundling, they can record these changes as they would be written in the traditional algorthim. </div><div><br /></div><hr /><div><b>Related Resources: </b><br /><div class="separator" style="clear: both; text-align: left;"><a href="https://www.teacherspayteachers.com/Product/24-Hour-Sale-Subtraction-With-Regrouping-Activities-4187210" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://1.bp.blogspot.com/-Mj6kRGoej3Y/W-d7RGsZp0I/AAAAAAAALOk/6jvWYY1Mti8DogI3sSKvR5rBmjjhfNlhgCLcBGAs/s200/Cover%2BUpdate%2B2.jpg" width="200" /></a></div><b><br /></b></div><div style="text-align: center;"><br /><img class="nopin" height="50" src="https://1.bp.blogspot.com/-iF93yAWRsQs/WUuigPmhuCI/AAAAAAAAL_g/pyHwSsJFEZ8Pvq1facQ-YnT8EoJmfF0YgCLcBGAs/s1600/signoff.png" width="150" /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-65326202697880810952018-11-02T15:50:00.005-04:002018-11-04T13:01:30.305-05:00Teaching Fractions on a Number Line <div class="separator" style="clear: both; text-align: center;"><a href="https://4.bp.blogspot.com/-XNvuyV-6CHM/W98z8ZyJWLI/AAAAAAAALHE/Xi7DYdii0PsNuA7oWRSRbBgB4KxIyvEswCLcBGAs/s1600/Teaching%2BFractions%2Bon%2Ba%2BNumber%2BLine.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="800" height="320" src="https://4.bp.blogspot.com/-XNvuyV-6CHM/W98z8ZyJWLI/AAAAAAAALHE/Xi7DYdii0PsNuA7oWRSRbBgB4KxIyvEswCLcBGAs/s320/Teaching%2BFractions%2Bon%2Ba%2BNumber%2BLine.png" width="213" /></a></div>For primary students, it is important for students to not only know how to count from 1-10 but to also <i>understand </i>the count sequence. <a href="http://www.k5mathspot.com/2016/03/understanding-count-sequence.html" target="_blank">I have written on this in the past</a> and suggested number path activities for our youngest students.<br /><br />Once our students enter 3rd grade and begin to explore fractions on a number line, I recommend similar activities!

As them to fold the paper so that the segments match the number line. You may have to give your students multiple strips of paper so they can experiment and play around- give them the chance to persevere in figuring it out! They can then label the unit fractions on the paper strip and lay it against the number line. </li><li><b>Representative</b>: Ask your students to color each segment of the number line in a different color. How many colors did it take to represent the different sections of the number line? Ask your students to label the unit fractions within the number line. </li><li><b>Abstract</b>: Once your students have had a bit of time to explore the number line through concrete and/or representative means, ask them why this line could NOT represent 3/4.

What I appreciated most about this text wasn't necessarily the math running records process (although I'll tell you, it's a great way to look at assessing fluency!) What I really loved about the text was her description of how facts are acquired and how students become fluent within their facts.<br /><br />You have heard me say, time and time again, that CRA (concrete, representative, abstract) is the way to go when it comes to teaching math and fact fluency is no exception! When learning about math facts students first need to understand the operation at the concrete level, they can then link that understanding to representations and, eventually, they will be able to perform at the abstract level solving problems through mental processes.<br /><br />The cool thing about fact acquisition is that you can apply the CRA process over and over to different types of facts.<br /><br /><b>Teaching +1 Facts?</b><br /><br /><ul><li>Why not start on a <a href="https://amzn.to/2qfBbU8" target="_blank">Rekenrek</a>!</li><li>As your students become fluent with the beads, this will become a strategy students can do mentally- and quickly! </li></ul><b>Teaching Doubles? </b><br /><br /><ul><li>Think about using dice and dot patterns. </li><li>Subitizing activities paired with an equation will help move these facts to the "fluent" column in no time. </li></ul><b>What About Make a Ten? </b><br /><br /><ul><li>Start with linking cubes in columns of ten. </li><li>Think about how to show this on a ten frame</li><li>Eventually, your students will become fluent with the strategy and associated facts. </li></ul><span style="font-family: inherit;">No matter which strategies you choose to teach fact fluency, know that moving from concrete to abstract is going to take A LOT of practice! This is why Greg Tang created games like <a href="https://gregtangmath.com/kakooma" target="_blank">Kakooma</a>. He wanted students to practice a high volume of facts so that once they are at the abstract stage these facts can become internalized and students will become fluent. </span><br /><span style="font-family: inherit;"><br />If you are a first or second grade teacher looking for practice for your students, I have created this set of <a href="https://www.teacherspayteachers.com/Product/Addition-Facts-Games-for-Sums-to-20-4157697" target="_blank">20 addition games</a> that I know you will LOVE.

The number of centimeters fewer is not something our students can see or touch, it's an abstract concept. </b></span><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-VN4XC60oUB8/W8oYU1Mqp9I/AAAAAAAAKt4/owUo3LL1BbI2z7X06IMInL64UTJjR9fyACLcBGAs/s1600/Pencils%2Bwith%2Bcubes.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="734" data-original-width="1079" height="271" src="https://2.bp.blogspot.com/-VN4XC60oUB8/W8oYU1Mqp9I/AAAAAAAAKt4/owUo3LL1BbI2z7X06IMInL64UTJjR9fyACLcBGAs/s400/Pencils%2Bwith%2Bcubes.png" width="400" /></a></div></div><span style="background-color: white; color: #222222;"><span style="font-family: inherit;">Lay centimeter cubes along the length of pencil A and pencil B. Ask your students again, </span></span><br /><span style="background-color: white; color: #222222;"><i><span style="font-family: inherit;">How long is pencil A?</span></i></span><br /><span style="background-color: white; color: #222222;"><i><span style="font-family: inherit;">How long is pencil B? </span></i></span><br /><span style="background-color: white; color: #222222;"><i><span style="font-family: inherit;">Which pencil is longer? </span></i></span><br /><span style="background-color: white; color: #222222;"><i><span style="font-family: inherit;">How much longer? </span></i></span><br /><span style="background-color: white; color: #222222;"><span style="font-family: inherit;"><br /></span></span><span style="background-color: white; color: #222222;"><span style="font-family: inherit;">This time, with the concrete modeling, many more of your students will be able to see how much longer pencil B is then pencil A!</span></span><br /><span style="background-color: white; color: #222222;"><span style="font-family: inherit;"><br /></span></span><span style="font-family: inherit;"><span style="background-color: white; color: #222222;">If you need to make this even more clear, push the two pencils together so that the centimeter cubes are right alongside one another. Your students can see pencil A and pencil B are the same up to 5 cm but pencil B has one, two, three more centimeters than pencil A. Pencil B is 3 centimeters longer!</span><br style="background-color: white; color: #222222;" /><br style="background-color: white; color: #222222;" /><span style="background-color: white; color: #222222;">At this point many or most of your students will be very successful with the comparison language, however... You don't want them to be at the concrete stage forever so, what can we do? We can use a part part whole diagram to represent the same thinking. You can see below that when we draw a pencil A as a box and pencil B as a box we can use a dotted line to show the difference between the two. At this point, the diagram makes it very clear that pencil A and the difference put together are the same as the length as pencil B. Your students can write a missing addend equation to solve for the part that shows the difference in the length of the pencils.</span><br style="background-color: white; color: #222222;" /><span style="background-color: white; color: #222222;"> </span><br style="background-color: white; color: #222222;" /><span style="background-color: white; color: #222222;">This will still be a difficult concept for your students! Don't expect them to learn the skill overnight. Most of your students will need extensive hands-on practice linked to the part-part-whole diagram many, <i>many</i> times before this will be an internalized understanding.</span><br style="background-color: white; color: #222222;" /><br style="background-color: white; color: #222222;" /><span style="background-color: white; color: #222222;"> At this point, your students have done vocabulary work and have expanded their math understanding and they will be much more successful with comparison word problems! </span></span><br /><span style="font-family: inherit;"><span style="background-color: white; color: #222222;"><br /></span></span><br /><h4><a href="https://3.bp.blogspot.com/-qLeYllmOBIw/W8tpanrBPkI/AAAAAAAAKxo/FaW-6zE3lzQfTSMtRv1V0EK_5PE7LHGgQCLcBGAs/s1600/Comparison%2BFreebie%2BCover.jpg" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="720" data-original-width="960" height="240" src="https://3.bp.blogspot.com/-qLeYllmOBIw/W8tpanrBPkI/AAAAAAAAKxo/FaW-6zE3lzQfTSMtRv1V0EK_5PE7LHGgQCLcBGAs/s320/Comparison%2BFreebie%2BCover.jpg" width="320" /></a><span style="font-family: inherit;"><span style="background-color: white; color: #222222;">I have created an entirely FREE set of comparison activities for you!

Find common denominators of course! You know, however, that I'm a big proponent of students understanding why they are using a strategy. If our students don't know why they are using a strategy so many of our learners don't know <i>when </i>to apply that strategy. They become students who have "strong rote skills but struggle with application".<br /><br />An incredibly effective method of helping our students to understand strategies is to give them concrete and representative experiences to make sense of an abstract strategy. I want to share 2 representative strategies for adding fractions with unlike denominators.<br /><br /><h4 style="text-align: center;"><span style="font-weight: normal;">Representative Methods of Adding Fractions </span></h4><div><a href="https://2.bp.blogspot.com/-SJImgsI26zc/W7ku2brvPPI/AAAAAAAAKQY/89ZXYO215SQqrOJH_aQRIoHlgclcdRD2QCLcBGAs/s1600/adding%2Bfractions.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="830" data-original-width="895" height="296" src="https://2.bp.blogspot.com/-SJImgsI26zc/W7ku2brvPPI/AAAAAAAAKQY/89ZXYO215SQqrOJH_aQRIoHlgclcdRD2QCLcBGAs/s320/adding%2Bfractions.png" width="320" /></a>Begin by representing each fraction.

In the example to the right, You can easily draw eighths over top of the fourths and fourths over top of the eighths to create two arrays each with 32 pieces.<br /><br />Once the two arrays are equal it is easy to add the two fractions together because you have found a common denominator of 32! </div><h4 style="text-align: center;"></h4><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-iqhYej5CKB8/W7ku2UdHqNI/AAAAAAAAKQg/F2w401Nc9Xcf2c9YsXi9EfBHgaVeYDreACLcBGAs/s1600/Adding%2BFractions%2BLCD.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="841" data-original-width="896" height="300" src="https://2.bp.blogspot.com/-iqhYej5CKB8/W7ku2UdHqNI/AAAAAAAAKQg/F2w401Nc9Xcf2c9YsXi9EfBHgaVeYDreACLcBGAs/s320/Adding%2BFractions%2BLCD.png" width="320" /></a></div><div style="text-align: center;"><div style="text-align: left;">You may be thinking to yourself that 32nds aren't necessarily easy numbers to work with and that the method is less than efficient.

If my students know that addition puts parts together, when we talk about counting on we will be talking all about how this is a <i>strategy to put parts together. </i>Down the line when your students see an addition sign, they won't default to the counting on procedure because "the plus sign means I grab the bigger number and count on". They will default to counting on IF it is an appropriate strategy because it is the most efficient strategy to put parts together.<br /><br /></div><h3 style="text-align: center;"> Context Is King</h3><div style="font-size: medium; font-weight: 400; text-align: left;"><a href="https://1.bp.blogspot.com/-gNsICLsgZqs/W6_HIPIiKoI/AAAAAAAAKEc/wqkjqhvA4M4V_4l7UjZaOZt7ErPNJ0p7wCLcBGAs/s1600/Bears%2Bin%2BCave%2BContext.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><span style="color: black;"><img border="0" data-original-height="563" data-original-width="656" height="273" src="https://1.bp.blogspot.com/-gNsICLsgZqs/W6_HIPIiKoI/AAAAAAAAKEc/wqkjqhvA4M4V_4l7UjZaOZt7ErPNJ0p7wCLcBGAs/s320/Bears%2Bin%2BCave%2BContext.png" width="320" /></span></a>So how do I teach my students to count on without outright stating "We can count on to add parts together. You count on by..."? I give my students a context that lends itself to counting on even though they don't yet know that strategy!<br />In this example, you can see that I have told my students there are 7 bears in the cave and 3 outside. I want them to figure out how many bears there are altogether without ever getting to see the bears inside the cave. This scenario lends itself <i>perfectly </i>to the counting on strategy. Once my students think they have solved the problem we can get out manipulatives to show 7 bears in the cave and 3 outside and discuss whether or not our counting on strategy was successful in putting the parts together.<br /><br /></div><h3 style="text-align: center;">Think CRA</h3><div style="font-size: medium; font-weight: 400; text-align: left;"><div><a href="https://4.bp.blogspot.com/-NVbGR26Ri-k/W6_HJhKh6-I/AAAAAAAAKEo/aIGlXmcs5lINyn7XZ1NK8G_i_egAmlynQCLcBGAs/s1600/Money%2BContext.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><span style="color: black;"><img border="0" data-original-height="1310" data-original-width="1090" height="320" src="https://4.bp.blogspot.com/-NVbGR26Ri-k/W6_HJhKh6-I/AAAAAAAAKEo/aIGlXmcs5lINyn7XZ1NK8G_i_egAmlynQCLcBGAs/s320/Money%2BContext.png" width="265" /></span></a>When teaching a new strategy that is more abstract in nature such as counting on, it's always helpful to think CRA. <a href="http://www.k5mathspot.com/2015/12/when-they-still-dont-get-it.html" target="_blank">Concrete, Representative, Abstract.</a> This means that when I begin teaching the strategy to my students I may start with an activity where I show them a wallet and tell them that there are $6 inside. Outside, there are $5 more. Students can try the counting on strategy but can touch, feel, and manipulate the dollars to solidify their thinking.<br />At some point, I would want to move to a more representative model such as the pictures of the bears in the cave shown above. In this way, our students are able to "trust" that there are a given number of bears in the cave. They are beginning to be comfortable manipulating the numbers without having to physically manipulate the scenario.</div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://4.bp.blogspot.com/-4ZknhDxR0oE/W6_HI_pZ1NI/AAAAAAAAKEg/jfHVdDYbCWMHKy_wPpi1c5Fkeh2xy0hpACLcBGAs/s1600/Abstract%2Bcounting.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><span style="color: black;"><img border="0" data-original-height="844" data-original-width="1125" height="240" src="https://4.bp.blogspot.com/-4ZknhDxR0oE/W6_HI_pZ1NI/AAAAAAAAKEg/jfHVdDYbCWMHKy_wPpi1c5Fkeh2xy0hpACLcBGAs/s320/Abstract%2Bcounting.png" width="320" /></span></a></div>Ultimately, when teaching counting on or when teaching any variety of other math strategies, you will want your students to be able to perform the strategy given an equation with pencil and paper or mentally. This is the abstract level and is best reinforced once your students have solidified the strategy through concrete and representative means.<br /><br /><i>Following these three steps will help to ensure that the strategies you are teaching are sticking for your students. You are truly teaching strategies rather than a standalone procedure! </i></div><div style="text-align: left;">________________________________________________________________________________</div><div style="text-align: left;"><b>Related Resources: </b></div><div class="separator" style="clear: both; text-align: left;"><a href="https://www.teacherspayteachers.com/Product/Counting-On-Addition-Strategy-4094700?aref=lu0dk6w0" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://2.bp.blogspot.com/-6Ens_hN_XuQ/W6_HEDvLPXI/AAAAAAAAKEY/qIihfs6cAIIylNjt-376d-v5bKp6yQLmwCLcBGAs/s200/Cover%2BUpdate%2B2.jpg" width="200" /></a></div><br /><br /><img class="nopin" height="50" src="https://1.bp.blogspot.com/-iF93yAWRsQs/WUuigPmhuCI/AAAAAAAAL_g/pyHwSsJFEZ8Pvq1facQ-YnT8EoJmfF0YgCLcBGAs/s1600/signoff.png" width="150" /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-18098258840276313402018-09-18T09:46:00.001-04:002018-09-18T09:46:14.546-04:00How To Teach Rounding to Struggling Learners<div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-0RAMH_ehigA/W6EBlr-7hvI/AAAAAAAAJzQ/rKC6nNMRt8o4FMREFNpTlXlE3_MLG7fDwCLcBGAs/s1600/Rounding%2BActivities.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1200" data-original-width="800" height="320" src="https://2.bp.blogspot.com/-0RAMH_ehigA/W6EBlr-7hvI/AAAAAAAAJzQ/rKC6nNMRt8o4FMREFNpTlXlE3_MLG7fDwCLcBGAs/s320/Rounding%2BActivities.png" width="213" /></a></div>If your grade level has standards around rounding numbers then you have thought long and hard about how to teach rounding to students who are struggling with math. There are two main schools of thought here. 1) Teach the students HOW to round. This may include a rhyme, an anchor chart, or another method that teaches a procedure that, when applied correctly, will result in rounded numbers. 2) Conceptually based methods such as a number line.<br /><br />The thing is, rounding is actually a very simple skill. <i>Students who struggle to round numbers most often don't have a misconception about how to round, they lack an internal number line and the number sense that allows them to be able to round. </i><br /><i><br /></i><br /><div style="text-align: center;">In other words, it's not a rounding issue, it's a number sense issue. </div><div style="text-align: center;"><br /></div><div style="text-align: left;">To teach struggling learners to round you want to spend the majority of your time developing number sense and, when you do, your students will pick up the skill of rounding quickly as a related after thought. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">Two main activities you will want to focus on are: </div><div style="text-align: left;"></div><ol><li>Identifying benchmark "round" numbers when counting by 10, 100, 1,000, tenths or whatever you may be rounding to. </li><li>Knowing how to count between these benchmark numbers. </li></ol><div style="text-align: center;"><b><u>Activities for Identifying Benchmark Numbers</u></b></div><div style="text-align: center;"><br /></div><div style="text-align: left;">Play round robin skip counting games like "Buzz". Students stand in a circle and you will identify a start number (ex: 250) and a buzz number (ex: 430). Starting with the start number students will count round robin from the start number to the buzz number. Whoever says the buzz number sits down and the game continues. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">Play "Find the Hidden Number" by giving students a number line counting by a particular interval (ex: 100, 200, 300, etc.) Ask students to point to the number line to find the spot where numbers are "hiding" (ex: Where is 438 hiding?) </div><div style="text-align: left;"><br /></div><br /><div style="text-align: center;"><b><u>Activities for Counting Between Benchmark Numbers </u></b></div><div><div style="text-align: center;"><br /></div><div>Write the numbers between two benchmarks on post-it notes. Post the benchmark numbers on a classroom white board and draw a number line between the two numbers. Give students the remaining post-it notes and ask them, one at a time, to determine the spot where they think their number would go. (ex: 4,500 to 4,600. Post-it notes include 4,510/4,520/4,530, etc) </div></div><div><br /></div><div>Repeat the same activity as on the post-it notes, however, give students their own white board and ask them to write in the numbers between two benchmarks. They may write all of the numbers at once or you may ask them to plot specific numbers in your chosen order. </div><div><br /></div><hr /><div><b><u>Related Resources: </u></b><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.teacherspayteachers.com/Product/5th-Grade-Decimal-Rounding-Activity-4053362?aref=frbkflyc" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://1.bp.blogspot.com/-wb4WtJ22ah0/W6D8ieCdFWI/AAAAAAAAJy4/S4Cf8loUIvUqSJu-JHT_h-aXWVOqA-A9gCLcBGAs/s200/Cover%2BUpdate%2B2.jpg" width="200" /></a><a href="https://www.teacherspayteachers.com/Product/Rounding-to-the-Nearest-10-100-and-1000-Worksheets-4068043?aref=frbkflyc" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://4.bp.blogspot.com/-U0PJxYJjghk/W6D8YHngzJI/AAAAAAAAJyw/COEEorBCWDY_Q0LBJ61RGAGq6GL2eUcHwCLcBGAs/s200/Cover%2BUpdate%2B2.jpg" width="200" /></a><a href="https://www.teacherspayteachers.com/Product/Rounding-To-the-Nearest-10-1493414?aref=frbkflyc" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://1.bp.blogspot.com/-sJ2NWGB1fjc/W6D8cBNyyOI/AAAAAAAAJy0/Wk9scSizQOASSNnP50w2-KRRiv2v0nAswCLcBGAs/s200/Cover%2BUpdate.jpg" width="200" /></a></div><br /><br /></div><div><br /></div><div style="text-align: center;"><img class="nopin" height="50" src="https://1.bp.blogspot.com/-iF93yAWRsQs/WUuigPmhuCI/AAAAAAAAL_g/pyHwSsJFEZ8Pvq1facQ-YnT8EoJmfF0YgCLcBGAs/s1600/signoff.png" width="150" /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-83768187944395096262018-09-12T14:28:00.006-04:002018-09-12T14:39:53.399-04:00Differentiate Worksheets Without Breaking a Sweat<div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-YTbhtHHkNk8/W5laXoLvGzI/AAAAAAAAJnw/CkYjY3TB4NU1aOJmt4N6rPeo5ET_4TUYQCLcBGAs/s1600/Differentiate%2BWorksheets%2B%25281%2529.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img alt="Worksheets are not one size fits all when it comes to how to teach math in an elementary classroom.

No, Really..." </a> It's been a few years but when I type "rounding" into Pinterest, 3 of the top 5 results still involve a search for an anchor chart.<br /><br />Anchor charts are great, but when your students have an <b>understanding of what rounding means</b> and <b>number sense around the numbers they are rounding</b> an anchor chart with a "Rounding Roller Coaster" is just not necessary. At all.<br /><br />In the original post mentioned above, I describe a method for rounding numbers to the nearest ten. The thing is, that exact same method can be used to round to any place! The difficulty when teaching rounding of decimal numbers to 5th graders is that you need to know where to begin. Some students have no concept of what rounding is while others know what rounding means but don't understand decimal numbers. Some students are missing both of these pieces! Using a number line we can get out in front of both of these major misconceptions to help our students to be successful.<br /><br /><div style="text-align: center;"><b><u>Understanding Rounding</u></b> </div><div style="text-align: center;"><br /></div><div style="text-align: left;"><a href="https://4.bp.blogspot.com/-HgImXuT6zfA/W5Vp-sZEm-I/AAAAAAAAJes/1wHG2Q56X_EV7IN7p0Z0f05d3uIRFRTPgCLcBGAs/s1600/Hundreds%2BRounding%2BHand.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="410" data-original-width="493" height="266" src="https://4.bp.blogspot.com/-HgImXuT6zfA/W5Vp-sZEm-I/AAAAAAAAJes/1wHG2Q56X_EV7IN7p0Z0f05d3uIRFRTPgCLcBGAs/s320/Hundreds%2BRounding%2BHand.png" width="320" /></a>Step 1 to rounding decimals (or any numbers) is for students to understand that rounding means finding the closest "round" number based on the place being rounded to. I like to play a game called "Find the Hidden Number" to reinforce this idea. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">Even when teaching rounding decimals, I start this activity with whole numbers. I want students to understand rounding and using "easier" numbers allows them to free up the mental space they need to think about rounding- not the numbers they are rounding! </div><div style="text-align: left;"><br /></div><div style="text-align: left;">Here you can see I have a number line with numbers between 0 and 1,000 counting by hundreds. To play "Find the Hidden Number" you will give your students a number and they will point to the spot where that number would be "hiding" on the number line. If you asked your students to find 624 they would need to point between 600 and 700. Then, ask your students which of those hundreds 624 would be closer to. If you find your students can't quickly and automatically tell you the closest hundred, chances are they are nowhere near ready to start rounding decimals- their understanding of whole numbers isn't even solid yet! </div><div class="separator" style="clear: both; text-align: center;"></div><br /><div style="text-align: center;"> <b><u>Decimal Number Sense </u></b></div><div style="text-align: center;"><b><u><br /></u></b></div><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-5rbfzJ6kV-k/W5VqAvNWgWI/AAAAAAAAJew/Vjp1iGZ4FcgREKDjuCqZeRghYtIey90lgCLcBGAs/s1600/Ordering%2BDecimals%2BHand.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" data-original-height="330" data-original-width="371" height="284" src="https://3.bp.blogspot.com/-5rbfzJ6kV-k/W5VqAvNWgWI/AAAAAAAAJew/Vjp1iGZ4FcgREKDjuCqZeRghYtIey90lgCLcBGAs/s320/Ordering%2BDecimals%2BHand.png" width="320" /></a></div><div style="text-align: left;">Once your students understand what it means to round by finding the nearest benchmark number, you will want to do number sense building activities around decimal numbers. One activity I love is ordering decimal numbers. I give students a blank number line and the numbers 0 and 1. One at a time, I give students number tiles for the tenths that come between 0 and 1 and ask students where on the number line these numbers would go. One at a time they place these numbers thinking about the scale and placement of numbers between 0 and 1. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">The first time through the activity I do not correct students who place a tile incorrectly. I simply wait for them to get the tile that would go in that spot and let the students notice for themselves that there is a problem with their placement. When students finish, clear the board and play again giving the tiles in a different order. Look for students who start to notice their previous errors and who are able to put the tiles on the board without any corrections throughout the game. This game can be played over and over with numbers between 0 and 1 or even between 0.05 and 0.06. The range is endless and will allow your students to practice understanding decimal numbers. </div><div style="text-align: left;"><br /></div><div style="text-align: left;">A variation on the game after your students are confident with the number tiles is to take the tiles away giving students only the end benchmark numbers and asking them to fill in the decimals that would come between by writing them in themselves. </div><div style="text-align: left;"><br /></div><div style="text-align: center;"><b><u>Putting It All Together </u></b></div><div style="text-align: center;"><b><u><br /></u></b></div><div style="text-align: left;">Now that your students understand what it means to round and they have number sense around decimal numbers, it is very simple to put the two skills together. Given a number such as 0.81 and asking students to round to the nearest tenth, here's how their thinking would play out. </div><div style="text-align: left;"></div><ol><li>Students would first know know "0.81 is between 8 tenths and 9 tenths" by playing "Find the Hidden Number". </li><li>Thanks to the number line activities, students would easily know that 0.81 is much closer to 8 tenths than 9 tenths. </li></ol><div><a href="https://www.teacherspayteachers.com/Product/Rounding-Decimal-Numbers-4053362" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="320" src="https://3.bp.blogspot.com/-LbNQfFqsscQ/W5VtONNxloI/AAAAAAAAJfE/qh_Menkty-gtj59Qai1Y4QXdo96C0ksIgCLcBGAs/s320/Cover%2BUpdate%2B2.jpg" width="320" /></a>No rhymes, no anchor charts with roller coasters, no tricks at all.

You are teaching your students routines and expectations setting the tone for the school year. On top of that, you are getting to know your students and beginning the process of building relationships with each of them.<br /><br />I find that I am able to build relationships when I am able to work in small groups with students. The extra attention students receive in a small group let them get to know me and lets me get to know them as a person but also how they function and think as a learner. I prioritize getting small groups up and running as soon as the routines in the classroom allow this to happen effectively!<br /><br />But what do you do in intervention groups in those early days? You likely haven't delivered a great deal of tier 1 instruction yet this year! The early weeks of the school year are the perfect time to get to know what your students have not mastered from the previous year and to get ahead of the game by tackling these deficits early on.<br /><br /><a href="https://www.teacherspayteachers.com/Product/Primary-Math-Intervention-Checklists-2062413?aref=a5cdraem" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;" target="_blank"><img border="0" data-original-height="960" data-original-width="960" height="200" src="https://4.bp.blogspot.com/-KdGx7wavoD0/W3bK4KikXZI/AAAAAAAAIyM/lux1k1fjtDoF8Txb5cOIaPLSQbeNjWxtACLcBGAs/s200/Cover%2BUpdate.jpg" width="200" /></a>I have created these <a href="https://www.teacherspayteachers.com/Product/Primary-Math-Intervention-Checklists-2062413?aref=a5cdraem" target="_blank">*free* checklists</a> to be used in kindergarten, first grade and second grade classrooms.

But what makes it so difficult for our students to understand and what can we do to make place value instruction more clear for our most struggling students.<br /><br />Quick and simple place value games can help your students to build understanding and gain fluency with place value concepts. But before I get to the games...<br /><br /><h3 style="text-align: center;"><b><u>Where do we start and where are we going? </u></b></h3><ul><li>In Kindergarten, students are building a foundation by noticing that when they have ten ones and some more ones they create a teen number. </li><li>In first grade, place value explodes with students understanding that ten ones can be put together to create a unit called a "ten" and that two digit numbers are really telling the number of "tens" and "ones". </li><li>In second grade this understanding is extended as students work their way up to 1,000 noticing that this pattern of grouping ten of a unit together yields a new type of unit. </li><li>In third grade students round and continue adding and subtracting multi-digit numbers... not a big place value year in terms of developing new ideas around the base ten system :) </li><li>In fourth grade students resume the extension of units all the way up to 1,000,000 and begin to notice that instead of just saying "ten of a unit yields a new unit" that they can describe the relationship of units next door do one another by saying 10 times more or 10 times less. </li><li>In fifth grade students tie together each of these previous understandings and apply them not only to whole numbers but to decimal numbers as well! </li></ul><div>It is clear that mastering the standard at each grade level is critical to moving on to the next grade level because each of these understandings is so closely related and builds so specifically on previous understandings. </div><h3 style="text-align: center;"><b><u>What does this mean for my instruction?</u></b> </h3><div>It means that your students can not leave your grade level with an emerging understanding of place value concepts! I would go as far as to say that in the world of "<a href="http://www.k5mathspot.com/2015/12/when-they-still-dont-get-it.html" target="_blank">Concrete-Representative-Abstract</a>" that students need to have moved as far down this continuum as possible before moving to the next grade level. </div><div><br /></div><div>That being said, I am a staunch advocate of letting students stay in the concrete and representative stages as long as is needed because it will help your students to be more solid in their abstract understandings and your students will be more efficient at mental math involving place value in general!</div><div><br /></div><h3 style="text-align: center;"><b><u>What will this look like on a daily basis?</u></b></h3><div><ol><li>Use SO MANY manipulatives when your students are learning about place value. </li><li>Use a variety of manipulatives- don't just get stuck using base ten blocks daily! When your students use a variety of manipulatives they are deepening their understanding and building connections between these models. </li><li>Be thoughtful about using pre-grouped, non-grouped, proportional and non-proportional models when choosing manipulatives and representations. </li><li>Link manipulatives, representative models and abstract equations together. For example, <i>if you can show your understanding using place value disks, that's great! Can you write an equation that matches what you just did with your disks? </i></li><li>Repetition, repetition, repetition. My third grade teacher used to say "Practice doesn't make perfect, practices makes permanent!" That means that when our students are practicing these skills it is important that they are practicing correctly and that they are practicing in great volume. What they do well and often will become permanent! </li></ol><div><a href="https://1.bp.blogspot.com/-epV95FNFRWE/W3MsCogGueI/AAAAAAAAItk/ZP9FKgAwd3Y8EihhFX0_F5OAWXwBXOwSQCLcBGAs/s1600/1%2Bor%2Bbust.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" data-original-height="1138" data-original-width="1359" height="267" src="https://1.bp.blogspot.com/-epV95FNFRWE/W3MsCogGueI/AAAAAAAAItk/ZP9FKgAwd3Y8EihhFX0_F5OAWXwBXOwSQCLcBGAs/s320/1%2Bor%2Bbust.png" data-pin-nopin="nopin" width="320" /></a></div></div><h3 style="text-align: center;"><u>So, What About The Games? </u></h3><div>Play games that promote repetition with linking of hands on tools to abstract ideas. The game "One or Bust" is an example of this type of game. Students choose a card and add that block to their game board. Students link their understanding between the concrete and the abstract as they play by stating aloud the change in their numbers as they progress through the game.

A few months back I was thinking that I needed something to supplement my income and came across VIPKID.<br /><br />At first, I wasn't sure if this company was for real, however, I was sold when I learned that VIPKID is Forbes' #1 online company to work for (<a href="https://www.forbes.com/sites/laurashin/2018/01/17/work-from-home-2018-the-top-100-companies-for-remote-jobs/#5b4ad0dc76f0" target="_blank">really!</a>).

You will set your schedule entirely. There's basically a grid of times 7 days a week and you open 30 minute time slots when you are interested in teaching. <b>You will teach only 1 student at a time. </b>If a student books a slot, you have committed to teach them. If no student has booked a slot, you have the flexibility to open and close that slot or adjust that timing as much as you would like. **It does take some time to be hired and to get your bookings going. If you are looking to do this in the summer, you will want to sign up now so you can get the ball rolling.** </li></ul><ul><li>VIPKIDs provides the interface, coordinates all of these sign-ups, provides teachers with as much or as little training as you are comfortable with AND PROVIDES ALL OF THE LESSONS. Yes. You do not have to lesson plan at all! </li></ul><ul><li>The interface basically looks like a PowerPoint on the left side of the screen, Skype in the middle with video feeds for teacher and student, and old school AIM to the far right where you can send text messages if needed. </li></ul><ul><li>The Fireman handle any and all IT issues. If I sign into a class and can't hear the student I just hit a button to "contact fireman" and the fireman will quickly show up and troubleshoot the issue. </li></ul><div>That's pretty much it. Student's sign up, teachers teach them with the provided materials, VIPKID takes care of all of the details and the fireman will be sure that IT issues are not even on your radar. </div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-myxsFTNxepc/WufAfSdADXI/AAAAAAAAHh4/PgbL9iLkBc8ZCit3I0OUI1zua3nPiT-3ACLcBGAs/s1600/How%2BMuch%2Bwill%2BI%2Breally%2Bmake.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="100" data-original-width="500" src="https://1.bp.blogspot.com/-myxsFTNxepc/WufAfSdADXI/AAAAAAAAHh4/PgbL9iLkBc8ZCit3I0OUI1zua3nPiT-3ACLcBGAs/s1600/How%2BMuch%2Bwill%2BI%2Breally%2Bmake.png" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"></div><br /><div>The company will tell you that you will make $14-22 per hour. That range seems large but here's how it works: </div><div><ul><li>When you have your interview you will be offered a base pay of $7-9 per class. Classes are each only 30 minutes so that puts us at $14-18 right off the bat. </li></ul><ul><li>If you show up to your class on time (which seems like a given... right??) you will get an extra $1 per class. So, if you are able to turn your computer on on time, you will be earning $15-19 per hour. </li></ul><ul><li>If you teach 30 classes in a month, you earn an extra $0.50 per class. (So now we're up to $16-$20 per hour) </li></ul><ul><li>If you teach 45 classes in a month, you earn an extra $1.00 per class. So, if your base pay is $9, you show up on time and you teach 45 classes in a month, you will earn (9x2)+(1x2)+(1x2)= $22 per hour. </li></ul>I personally have a base pay of $8 per hour, always show up on time, and generally teach about 30-40 classes per month. This leaves me making $19/hour. I accomplish 30 classes per month by teaching 1 class before school on Monday, 1 class before school on Friday and 2-4 classes per day each on Saturday and Sunday morning. This is about $150-190 per week for a very minimal commitment. My personal plan is to open more slots during the summer but, for the school year, this is enough to keep me busy and satisfied on the side! </div><div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-1yfgX-gKkS4/WufAhZseOQI/AAAAAAAAHh8/Gfbfh2WV2PwosUQYXV26DGz1KtdubeFIwCEwYBhgL/s1600/Is%2BThere%2Ban%2BInvestment_.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="100" data-original-width="500" src="https://3.bp.blogspot.com/-1yfgX-gKkS4/WufAhZseOQI/AAAAAAAAHh8/Gfbfh2WV2PwosUQYXV26DGz1KtdubeFIwCEwYBhgL/s1600/Is%2BThere%2Ban%2BInvestment_.png" /></a></div><div><br /></div></div><div>Yes, but it is incredibly minimal.

That's just not me or my personality! I have found that by being myself and teaching in a way that I feel comfortable I am able to fill all 8-10 slots that I would like to teach per week. I have regular students who come back to me lesson after lesson. Because I don't put on a show I attract the older students who I <i>really </i>enjoy teaching, talking to, and connecting with! I am NOT putting down teachers who put more into it than I do! I encourage everyone to find their style, find what they are comfortable with and enjoying and pursue that avenue fully!

A bar graph or pictograph is really quite intuitive to read- the difficulty in instruction comes in when students are asked to solve comparison word problems based on the data in the charts. And we KNOW that comparison word problems are notoriously difficult for students to solve as word problem types go.<br /><div class="separator" style="clear: both; text-align: center;"></div><br /><br />Why then are line plots... which are really just a combination of a bar graph and a pictograph... so difficult for students to read and answer questions about? If we really drill down, creating a line plot and answering questions about a line plot in 4th and 5th grade requires so many components. Understanding which of these components are strengths and areas of need for your students can help you to narrow in on the reason they might be having difficulty. To build and interpret a line plot, students need:<br /><br /><ol><li>An understanding of the conventions of putting the chart together.</li><li>A thorough understanding of what each part of the line plot represents for interpretation.</li><li>Last of all, but certainly not least of all, an extensive understanding of fractions on a number line.</li></ol><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-TXZBipBnaxY/WOv7HkDGfTI/AAAAAAAAEkE/wY5HP6ko3_wMvmRTFQABicL07x2Ch10zACLcB/s1600/Fractions%2Bon%2Ba%2BNumber%2BLine.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://3.bp.blogspot.com/-TXZBipBnaxY/WOv7HkDGfTI/AAAAAAAAEkE/wY5HP6ko3_wMvmRTFQABicL07x2Ch10zACLcB/s640/Fractions%2Bon%2Ba%2BNumber%2BLine.png" width="640" /></a></div><br />In creating a line plot students first need to create a number line. When looking at the data set, helpful questions to ask students would include:<br /><br /><br /><div><ul><li>What is the smallest fraction in the data set? How can this help us decide where to start the number line?</li><li>What is the largest fraction in the data set? How can this data point help us to decide where to end the number line? </li><li>Where would 1/2, 1/4 and 1/8 be place on the number line. Where do the 1/4 and 1/2 marks overlap? Where do the 1/8 marks overlap with the other fractions. If 2/4 and 1/2 are at the same point, what does that tell us about these fractions? </li></ul><div><b>So what can you do to help? Give students a hands on opportunity to build a line plot. Give them a set of pencils or clip art pictures all measured to different lengths. Have students place these items out on a life-sized line plot so that they can see where it would make sense to start a number line, end a number line and how the number line could be best labeled. </b></div></div><div><b><br /></b></div><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://4.bp.blogspot.com/-RL6tZjWxolM/WOv7I6t1HfI/AAAAAAAAEkI/sFzw5kk8jTAYkkPQdKiqq0EXb9ZiM-_7wCLcB/s1600/Line%2BPlot%2BConventions.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://4.bp.blogspot.com/-RL6tZjWxolM/WOv7I6t1HfI/AAAAAAAAEkI/sFzw5kk8jTAYkkPQdKiqq0EXb9ZiM-_7wCLcB/s640/Line%2BPlot%2BConventions.png" width="640" /></a></div> The conventions of creating a line plot aren't all that different from creating a bar graph, pictograph, or any other type of graphing representation. Students need to be sure to include a title, a number line, a label for the number line, they need to mark out a scale on the number line, and finally to represent their data points.<br /><br /><b>So what can you do to help? It may be helpful to students to link the conventions of a line plot to the conventions of other types of graphs that they already know about. We know that research tells us that whenever we can make links and connections information will stick more easily. Could students look at a bar graph of similar information and find each of these components on both the bar graph and the line plot? </b><br /><br /><ul><li>Where on the graphs do we learn what the graph is all about? </li><li>Where on the graphs do we find out, for example, the height of the smallest plant?</li><li>Where on the graphs do we find out if they are measuring, for example, in inches or centimeters? </li><li>Where on the graphs can we find out how many plants, for example, are 3 1/2 inches tall? </li></ul><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-8imxiaYI03I/WOv9Rd161bI/AAAAAAAAEkY/ZYoZtwoQfQQtTFo9U03wjUb6vcnZsQzgwCLcB/s1600/Line%2BPlot%2BInterpretation.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://3.bp.blogspot.com/-8imxiaYI03I/WOv9Rd161bI/AAAAAAAAEkY/ZYoZtwoQfQQtTFo9U03wjUb6vcnZsQzgwCLcB/s640/Line%2BPlot%2BInterpretation.png" width="640" /></a></div><div><br /></div><br />A number of difficulties are presented when students are asked to interpret the information on a line plot.<br /><br /><ul><li>If students are creating a number line about the height of a variety of plants- do they really recognize that each "X" on the line plot stands for it's own plant? If they don't, they are going to have a very difficult time in answering a question that asks, for example, "What is the total height of all of the plants measured?" <i>You will know if students aren't understanding the meaning of the "X" if students add up all of the fractions listed on the scale rather than adding up the total of all data points. </i></li><li>Students may need to add fractions with different denominators. If a set of data has pieces measured to the nearest 1/4 inch there is a good chance some pieces of data will be listed as 1/2. The same situation may occur if data points are measured to the nearest 1/8th. Students may have more difficulty performing operations on fractions with different denominators. </li><li>Students may have difficulty understanding that each piece of data has multiple labels. For example, consider the story <i>Mike road his bike every day for a week. On each day he wrote down the number of miles he traveled. In his journal his list said: 2 1/4, 3, 5 1/2, 3 1/4, 3 1/4, 5, 2. </i>In this example story, each of these pieces of data really has 2 labels. The first piece of data, 2 1/4, really represents that on <b>day 1, </b>Mike traveled 2 1/4 <b>miles. </b>Each of the pieces of data is a separate day and each of those days has been measured in miles. </li></ul><div><b>So what can you do to help? I stand by my suggestions in the first two paragraphs. If students are not making these connections when they are looking at a line plot on paper you can either take the line plot off of the paper and bring it into real, hands on life so students can understand the significance and meaning of each "x" on the line plot. You can also relate the line plot to other graphs and representations you use in the classroom to help students to build connections! </b></div><div><br /></div><div><a href="https://www.teacherspayteachers.com/Product/Line-Plots-Reading-and-Creating-1002321" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;" target="_blank"><img border="0" height="150" src="https://2.bp.blogspot.com/-q9NKYeqte-k/WOwBX8XS67I/AAAAAAAAEkk/M6VSJDYVA9w1VG678o9qSMXMv5CGrMWQQCLcB/s200/Line%2BPlot%2BWorksheet%2BCover.jpg" width="200" /></a><a href="https://www.teacherspayteachers.com/Product/Reading-and-Creating-Line-Plots-with-Fractions-1303404" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;" target="_blank"><img border="0" height="150" src="https://3.bp.blogspot.com/-DQXTmPkOYBY/WOwBdmLbcQI/AAAAAAAAEks/La5KGc7TBM8cCh6pj5cV0I5la9QaI0w2wCLcB/s200/Slide1.JPG" width="200" /></a>If you are looking for further line plot resources, I have two resources that might be helpful.

There has been quite a bit of research about the importance of grit in allowing students to learn and be successful both in school and beyond. I love research, it fuels the choices that I make in the classroom, but I'll be honest, if I can't figure out how a piece of research <i>looks </i>in my teaching, I have a hard time.<br /><br /><a href="https://4.bp.blogspot.com/-y_s4IgiBbyI/WMldbG_LtwI/AAAAAAAAEgQ/BIC5W8OK7xE1ZZxMGdExTT1gXWV5AjZlACLcB/s1600/It%2527s%2Btime%2Bto%2Bget.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="320" src="https://4.bp.blogspot.com/-y_s4IgiBbyI/WMldbG_LtwI/AAAAAAAAEgQ/BIC5W8OK7xE1ZZxMGdExTT1gXWV5AjZlACLcB/s320/It%2527s%2Btime%2Bto%2Bget.png" width="213" /></a>The grit research, to me, was difficult because while I could understand the connection between grit and success I didn't think it was enough to be sure I was careful with the language that I was using so that I was using language that promoted a growth mindset and diminishing language that would reinforce a fixed mindset.<br /><br />I had a principal once that told us that we needed to think of our profession as being equal to the medical profession. That we were diagnosticians and practitioners and that we needed to keep up with current research. If we weren't implementing best practice that would be considered equal to a doctor committing malpractice. It sounds harsh but you really can't argue with the logic!<br /><br />And so I kept thinking about grit and how I could be more explicit- beyond being purposeful in my choice of language. I needed my students to know what they were working towards! <b>I have figured out how to make this connection more explicit and wanted to be sure to share this strategy with all of you.</b><br /><br />I have taught my students that, sometimes, at the end of a math lesson they will feel very confident. <i>This means that they have met the learning target, they might have gotten many questions correct on their exit ticket, they might even be thinking something like "this is easy!". </i>If they are feeling that way they can say that they are having a confident day in math. Other days we might be working on something that feels really tricky! <i>They may feel confused or they might feel like they are thinking really hard but it's still not making a lot of sense. They might start to feel frustrated because even though they are trying, they keep getting answers wrong. They might even see other students having a confident day and they might be wondering why it's not easy for them. </i>I tell my students that if they are feeling like they are having a day that is very tricky they have two choices. They can either get mad/sad/frustrated or they can <b>get gritty. </b>Gritty means that you hunker down and say "I can figure this out!" "I can work at this!" "I will be able to do it!!".<br /><br /><a href="https://2.bp.blogspot.com/-wNu7caLFhM0/WMlicrOJpvI/AAAAAAAAEgg/hnkrKLP-c-cSQUlNJBRMqNJg4JwKeacWgCLcB/s1600/Grit%2BMindset.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="320" src="https://2.bp.blogspot.com/-wNu7caLFhM0/WMlicrOJpvI/AAAAAAAAEgg/hnkrKLP-c-cSQUlNJBRMqNJg4JwKeacWgCLcB/s320/Grit%2BMindset.png" width="213" /></a>When we are "getting gritty" we even go so far as to make a little fist and make a "tough" face and say "I can get this!!" I practice this with my kids outside of the context of math at the beginning of a lesson. I remind them by saying <i>"We're going to work on some pretty important stuff today! You might get it right away and have a confident day, but if it's feeling tough remember, you can always get gritty and we'll figure it out together. Show me what you will say when you're feeling gritty" </i>and they respond by all saying, emphatically, "I can get this!"<br /><br />During a lesson when a student is struggling I can then easily put their mind at ease by acknowledging that the work is difficult and that I know they can get gritty and figure it out.<br /><br />You see, my students know that those two choices they have when work gets hard lead to very different results. If they get mad/sad/frustrated they will still be mad/sad/frustrated at the end of the lesson. If they get gritty, they have a chance of moving over and becoming confident.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-pl-wDVSFkXk/WMlvpbqa8YI/AAAAAAAAEg0/PD_aqhZt3_k7g7ZJiDTw_FrIYqGoyypLgCLcB/s1600/Grit%2BMindset%2B2.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="320" src="https://2.bp.blogspot.com/-pl-wDVSFkXk/WMlvpbqa8YI/AAAAAAAAEg0/PD_aqhZt3_k7g7ZJiDTw_FrIYqGoyypLgCLcB/s320/Grit%2BMindset%2B2.png" width="320" /></a></div>Not every math day ends in success for all students. And that's okay. And I want my students to know this is okay too! At the end of a lesson we will often reflect and ask "Who had a confident day? Who had to get gritty today?" and I am able to praise them for sticking to it and working even when the work got tough. I remind them of opportunities they will have in the future to continue practicing this work.<br /><br />I am including a reflection to use in your classroom either after a math lesson or at any other time during the day when you are noticing that there are some students who could use some reassurance. If students were able to "get gritty" they had a successful learning day and their efforts should be celebrated!<br /><br /><div style="text-align: center;"></div><!-- Begin MailChimp Signup Form --> <br /><div id="mc_embed_signup"><form action="https://k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c13b65c715" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h3 style="text-align: center;">Sign Up Here to Grab Your Learning Reflection</h3><div class="indicates-required"><div style="text-align: center;"><label for="mce-EMAIL">Email Address <span class="asterisk">*</span></label> <input class="required email" id="mce-EMAIL" name="EMAIL" type="email" value="" /></div></div><div class="mc-field-group"><div style="text-align: center;"><label for="mce-FNAME">First Name </label> <input class="" id="mce-FNAME" name="FNAME" type="text" value="" /></div></div><div class="mc-field-group"><div style="text-align: center;"><label for="mce-LNAME">Last Name </label> <input class="" id="mce-LNAME" name="LNAME" type="text" value="" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c13b65c715" tabindex="-1" type="text" value="" /></div></div><div class="clear"><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe" name="subscribe" type="submit" value="Send Me My Freebie!" /></div></div></div></form></div>The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-70142903174573214292017-03-12T09:08:00.002-04:002018-10-21T14:36:23.297-04:00The Math Spot Compares Fractions: Abstract Thinking We've made it! We're at the last post in the 4 part fraction comparison series.

Up until this point we have focused on teaching fraction comparisons by allowing students to have experiences that would promote understanding of fractions and fractional parts. <br /><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">The concrete, representational, abstract (CRA) framework taught us to begin with concrete experiences and to link those experiences to both representations and abstract thinking. The focus of this post is concerned with promoting concrete thinking but, you may have noticed, that questions that point towards concrete thinking have been embedded in both the concrete and representational work that have been done thus far. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">This is really the heart of the CRA framework- you are making links to abstract thinking all along the way! <b>That is to say that abstract is not it's own isolated step.</b> I'm not saying students shouldn't explicitly practice at the abstract level- of course they should to build fluency with the skill they are navigating. Students benefit from opportunities to access and apply their previous knowledge in order to become fluent in a skill. But, generally, "abstract" is not a stand alone step. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;"><a href="https://1.bp.blogspot.com/-4DGAaapDnDg/WMVIRQcR3GI/AAAAAAAAEcw/o8_6tJxUacsZJjp3Jln0agKozdee-n8IgCLcB/s1600/Depositphotos_19438669_original.jpg" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="152" src="https://1.bp.blogspot.com/-4DGAaapDnDg/WMVIRQcR3GI/AAAAAAAAEcw/o8_6tJxUacsZJjp3Jln0agKozdee-n8IgCLcB/s200/Depositphotos_19438669_original.jpg" width="200" /></a>Notice on day 1 when you introduced fractions with an "Epic" story problem.

I suggested that as you go through the Epic story problem that you chart what happens to the candy bar as more friends show up.

If you haven't read<a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions-four.html" target="_blank"> post #1 </a>and <a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions.html" target="_blank">post #2</a> take a quick break to go and read those now! <br /><br />Now that we are all caught up, let's do a quick recap of the big ideas:<br /><br /><ul><li>Students have had A LOT of experience in the whole number world. They WILL make generalizations that don't necessarily work for fractions if you don't ground them in concrete experiences. </li><li>Concrete experiences come in all sorts of shapes and sizes! There is no one perfect concrete model and the more concrete experiences you expose your students to the more anchors they have from which to draw future connections. </li></ul><div>But here's the thing. You've heard your colleagues say it and you have probably said it yourself... "In the real world they aren't going to be able to whip out their pattern blocks and say 'Hold on while I figure this out with my shapes!'". </div><div><br /></div><div>And you and your colleagues would be 100% right. This is exactly why I stress that it's a concrete, representative, abstract PROGRESSION. You start in concrete activities and begin to link those to representative models and abstract ideas. Depending on the topic you are teaching this may happen over the course of one lesson or over the course of multiple weeks! It is so important that you be in tune with your students and that you are able to move within the progression in a way that is responsive to their needs. </div><div><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-2W4DUVqM_AA/WLxHDwICUCI/AAAAAAAAEZE/R3lH-ZvkNCUxEq7YbH3NUKHFTUQ0STmBwCPcB/s1600/Fraction%2BBars.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://1.bp.blogspot.com/-2W4DUVqM_AA/WLxHDwICUCI/AAAAAAAAEZE/R3lH-ZvkNCUxEq7YbH3NUKHFTUQ0STmBwCPcB/s640/Fraction%2BBars.png" width="640" /></a></div> In post #2 I mentioned using fraction bars in a variety of forms including Cuisenaire Rods and Fraction bars or tiles. A logical representative step from these type of models would be to move towards a tape diagram. The prompt can be as simple as "Can you draw a tape diagram to match your fraction bars?" From there you will want to ask the students many questions to be sure they are drawing explicit connections between the concrete and the representative models.<br /><a href="https://2.bp.blogspot.com/-hfBuLlsXU9g/WMSoljvBe3I/AAAAAAAAEb4/34zppITyiQIgYgfMLqWYp5U89Vr94zY9gCLcB/s1600/IMG_4518.PNG" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://2.bp.blogspot.com/-hfBuLlsXU9g/WMSoljvBe3I/AAAAAAAAEb4/34zppITyiQIgYgfMLqWYp5U89Vr94zY9gCLcB/s200/IMG_4518.PNG" width="200" /></a><br />Consider giving students a task such as <i>Use fraction bars to show whether 1/4 or 1/2 is greater. </i>After the students had built models for 1/4 and 1/2 you would then say to them <i>Draw a tape diagram that matches your fraction bars to show whether 1/4 or 1/2 is greater. </i>Ask students to discuss with one another how their pictures match the bars or tiles that they built with. Ask students to point to the part in their drawing that matches the 1/2 bar. Ask students to point to the part in their drawing that matches the 1/4 tiles. Point out the discrepancies that you notice that a student doesn't! Are they not noticing that the whole needs to be the same size in their 1/2 and 1/4 tape diagrams? Ask students to describe, describe, describe how they came up with their representation. Before you know it, they will be able to use tape diagrams to show these comparisons without needing the materials first.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-pLPXeWT0FwE/WLxIfvABGRI/AAAAAAAAEZE/VlSL8-SI5WEE3gdbThABWQgAniQZe2bBACPcB/s1600/Epic%2BStory%2BProblems.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://3.bp.blogspot.com/-pLPXeWT0FwE/WLxIfvABGRI/AAAAAAAAEZE/VlSL8-SI5WEE3gdbThABWQgAniQZe2bBACPcB/s640/Epic%2BStory%2BProblems.png" width="640" /></a></div> All drawings don't need to be formal. I described using a tape diagram above but an informal drawing that represents what happened in a story problem will go very far in terms of allowing students to develop a spatial understanding of the fractions they are working with.<br /><br />Consider if you had told students an "epic" story problem about a round pizza. It would be a much larger leap for your students to make a matching drawing if you asked them to do so with a tape diagram. I am NOT saying that you shouldn't ask them to use a tape diagram to represent a "round" problem. But I am advocating that if you know moving to a drawing or representation will be a challenge for your students that you begin by asking them to make a representation that more closely aligns with the original problem. You can spend time in more than one concrete model or more than one representation. It would be beyond fair for you to ask students to draw circles showing what happened to a pizza and then asking them to draw a tape diagram that matches their circles.<br /><br />This is a progression, it is about being thoughtful, it is about knowing your students, it is about being as developmentally mindful as you can while building these big concepts!<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-YNjw_E5gmLg/WLxIfsrt0qI/AAAAAAAAEZE/mQyNNjlz1sI0iAzLQLVsyLgEIOLKWRaIgCPcB/s1600/Rulers.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://3.bp.blogspot.com/-YNjw_E5gmLg/WLxIfsrt0qI/AAAAAAAAEZE/mQyNNjlz1sI0iAzLQLVsyLgEIOLKWRaIgCPcB/s640/Rulers.png" width="640" /></a></div> You may have heard that in the primary (K-2) world there is a BIG difference for students if they are counting to 10 on a number line vs. a number path. A number line marks the "end" of each period whereas a number path consists of adjoining boxes each representing a piece to the path. For primary students it is much easier to understand a number path than a number line because they can see that two, for instance, is two boxes on a number path. On a number line 2 looks like a finite point and they don't necessarily understand that everything up to that two constitutes the whole 2 we are talking about.<br /><br />In the intermediate world you can liken this to the difference between a tape diagram and a number line. A tape diagram is essentially a number path- you can see the full box that constitutes each period. A number line is much more difficult to interpret.<br /><br />A ruler, however, is a tool that many students are very familiar with and, if you use rulers with only specific fractions marked off (see post #2 for concrete examples) your students will be set up for success in number line work. Students can begin moving toward a number line by drawing and representing what they found on a ruler on a number line. To further ease the transition of using a number line to represent fractions, you may ask your students to shade in or highlight the number line up to a given number. This will create a visual that is almost a hybrid between a tape diagram and a number line.<br /><div class="separator" style="clear: both; text-align: center;"></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-adAIxN7UgBQ/WMh_ecugOXI/AAAAAAAAEfU/7MnCXpsVhPYFb_ly7wonmAZNaJLoxNGQwCLcB/s1600/Paper%2BClips%2B%25283%2529.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://1.bp.blogspot.com/-adAIxN7UgBQ/WMh_ecugOXI/AAAAAAAAEfU/7MnCXpsVhPYFb_ly7wonmAZNaJLoxNGQwCLcB/s640/Paper%2BClips%2B%25283%2529.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"></div><div><div class="separator" style="clear: both; text-align: center;"></div><a href="https://4.bp.blogspot.com/-xFwEmbg0NRY/WMSo1JWhzBI/AAAAAAAAEb8/joziHJAqYtkOdyurKozc9KudDjp0823BQCLcB/s1600/IMG_4515.JPG" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="200" src="https://4.bp.blogspot.com/-xFwEmbg0NRY/WMSo1JWhzBI/AAAAAAAAEb8/joziHJAqYtkOdyurKozc9KudDjp0823BQCLcB/s200/IMG_4515.JPG" width="200" /></a>I described in the previous post how students could use pattern blocks to explore unit fractions and beyond when they are first comparing fractions. A simple transition between concrete and abstract is presented when your students are learning with pattern blocks. Students can simply trace the pattern blocks and label the unit fractions on their drawings. In this way, students can represent unit fractions while still having the opportunity to manipulate the materials first.<br /><br />As mentioned many times, throughout this post and the previous two, the real power in the C-R-A framework is asking the questions that join together the concrete models to the representations that students are drawing or interpreting. Ultimately, these connections will help students to begin to think in a more abstract way about these numbers and concepts.<br /><br />In my next post I will help you to tie it all together and to ask questions that are dangerously effective towards helping your students to achieve mastery in fraction comparison! </div><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions-four.html" target="_blank">Post 1: The Math Spot Compares Fractions- Introduction</a><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions.html" target="_blank">Post 2: The Math Spot Compares Fractions- Comparison Tools</a><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions_9.html" target="_blank">Post 3: The Math Spot Compares Fractions- Representative Models</a><br /><a href="https://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions_12.html" target="_blank">Post 4: The Math Spot Compares Fractions- Abstract Thinking</a><br /><div style="text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-c7NJQIXls8w/VzcbEKvXhII/AAAAAAAAIgQ/QeUVKZ3VCwwtLDo9-Ol9_3ckjdzU6gHegCPcBGAYYCw/s1600/signoff.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="92" data-original-width="245" src="https://2.bp.blogspot.com/-c7NJQIXls8w/VzcbEKvXhII/AAAAAAAAIgQ/QeUVKZ3VCwwtLDo9-Ol9_3ckjdzU6gHegCPcBGAYYCw/s1600/signoff.png" /></a></div><br /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0tag:blogger.com,1999:blog-6278540421686629919.post-90192688153861209782017-03-05T15:05:00.000-05:002018-10-21T14:35:30.386-04:00The Math Spot Compares Fractions- Comparison Tools <div class="separator" style="clear: both; text-align: center;"><a href="https://3.bp.blogspot.com/-eJ_c1HN8IVo/WLjSdZUdmBI/AAAAAAAAEYA/GqMS0L9gTQ4uETTbaZgvAP7GH_No0FGgACPcB/s1600/Copy%2Bof%2B3%2BSteps%2BTo%2BA.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="https://3.bp.blogspot.com/-eJ_c1HN8IVo/WLjSdZUdmBI/AAAAAAAAEYA/GqMS0L9gTQ4uETTbaZgvAP7GH_No0FGgACPcB/s320/Copy%2Bof%2B3%2BSteps%2BTo%2BA.png" width="320" /></a></div><br />When I taught 4th grade special ed. I found that fractions in the context of a story made so much sense to my students. I would come up with elaborate scenarios - most involving food- that would start out by granting one student exclusive rights to an entire pan of brownies and would slowly erode their good fortune to the end of changing denominators and, ultimately, fraction learning. These were the days when I would hear cries of "You're the best teacher ever!" and "Math is so much fun!"... I get it, I was feeding them brownies. But they were learning so this was a true win-win scenario.<br /><br /><a href="https://4.bp.blogspot.com/-63L2FZVmqO0/WLx8CD5WU4I/AAAAAAAAEZQ/NDr-SUKlcOkSmjK83Jn7LLC5bZKdot-UgCEw/s1600/Comparing%2BFractions%2BManipulatives.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://4.bp.blogspot.com/-63L2FZVmqO0/WLx8CD5WU4I/AAAAAAAAEZQ/NDr-SUKlcOkSmjK83Jn7LLC5bZKdot-UgCEw/s200/Comparing%2BFractions%2BManipulatives.png" width="200" /></a>In my <a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions-four.html" target="_blank">first post of the comparing fractions series</a> I talked about how students make connections based on what they know. Coming out of the primary grade levels our students know a lot about whole numbers- but the rules of the whole number world don't always apply to fractions in the way that our kids think they will. It is so important to give our students opportunities to have concrete experiences with fractions so that they have solid anchors for their future fraction connections. My recommendation, however was not only to start with concrete experiences but to follow the <a href="http://www.k5mathspot.com/2015/12/when-they-still-dont-get-it.html" target="_blank">concrete-representative-abstract (CRA) model. </a><br /><br />This post will focus on a variety of concrete models and experiences that will help your students to form a strong anchor for their fraction learning. Anchors that you can easily connect to in representative and abstract ways through future lessons. I am recommending these in no particular order. Think about your students and the hands on experiences that you think might best resonate with them.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-2W4DUVqM_AA/WLxHDwICUCI/AAAAAAAAEYo/f9wU8aOdDFs4oXM1fBJRfvqaVv_ticnPACLcB/s1600/Fraction%2BBars.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://2.bp.blogspot.com/-2W4DUVqM_AA/WLxHDwICUCI/AAAAAAAAEYo/f9wU8aOdDFs4oXM1fBJRfvqaVv_ticnPACLcB/s640/Fraction%2BBars.png" width="640" /></a></div><a href="https://4.bp.blogspot.com/-LA2vpb53nII/WLx8CY_r-II/AAAAAAAAEZU/NmfXF2djYXUsl_phdYmCzuQpbZ72rsY0QCLcB/s1600/Fraction%2BBars%2BComparison.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="200" src="https://4.bp.blogspot.com/-LA2vpb53nII/WLx8CY_r-II/AAAAAAAAEZU/NmfXF2djYXUsl_phdYmCzuQpbZ72rsY0QCLcB/s200/Fraction%2BBars%2BComparison.png" width="200" /></a>A variety of fraction bars will be an indispensable tool when you are helping students to understand how to compare fractions. Cuisenaire Rods are a great first tool for exploration. Choosing one rod and naming it "the whole" ask your students to determine which color rod would represent 1/2, 1/3, 1/4 or 1/8. I love the connecting rods that I have listed under "tools" below because there is no risk of sloppy work leading to incorrect understandings.<br /><br />In the same vein, fraction bars will allow your students to see a similar relationship between the size of the fraction pieces. In this model you are losing the opportunity for your students to discover on their own the relationship between the size of the pieces, however, depending on the task your students have been given, this is just fine. For example, if your students already have an understanding of naming unit fractions and you are asking them to compare a variety of fractions and report what they are noticing about the pattern of denominators, fraction bars will be the perfect tool for your students to use.<br /><br />The last fraction bar model that I will mention- in this FAR from exhaustive list- is folded paper strips. Much like the Cuisenaire Rods, students will have an opportunity to reason about the size of the pieces as they are folding the strips into equal groups. I like this activity as more of an exploration because I will warn you that alternate conversations will emerge. Depending on the fine motor skills of your students, you will surely have students who do not fold into equal pieces.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-FTpNpCvJW7s/WLxIfh_k-_I/AAAAAAAAEYw/oCNwf2qVfTQu8ab-Bj4otuuc1h4bMngiwCLcB/s1600/Food.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://2.bp.blogspot.com/-FTpNpCvJW7s/WLxIfh_k-_I/AAAAAAAAEYw/oCNwf2qVfTQu8ab-Bj4otuuc1h4bMngiwCLcB/s640/Food.png" width="640" /></a></div>Food is a natural opportunity for students to experience fractions in a "real life" scenario. It also allows students to bring common sense into the equation. If I am sharing a pizza with 10 friends I will obviously get less pizza than if I am only sharing with one other person. The key here is to make sure that as you are using food like pizza, brownies, chocolate bars... <i>are you hungry yet?...</i>that you ask questions that will allow students to connect this understanding directly to fractions. Use fraction language. Chart out what happens as you cut the food into more and more pieces. Ask students what they notice about the denominators. Ask them to make predictions based on what they are noticing in the numeric patterns and then keep cutting the food up (or putting pieces back together) to test their conjectures.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://1.bp.blogspot.com/-pLPXeWT0FwE/WLxIfvABGRI/AAAAAAAAEY0/vrsw0jyfKkIHZZE6rH6uXovJ8bm0d_nkgCLcB/s1600/Epic%2BStory%2BProblems.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://1.bp.blogspot.com/-pLPXeWT0FwE/WLxIfvABGRI/AAAAAAAAEY0/vrsw0jyfKkIHZZE6rH6uXovJ8bm0d_nkgCLcB/s640/Epic%2BStory%2BProblems.png" width="640" /></a></div> I'll be honest. Most of the "epic" story problems I have written are about food. I'm not apologetic though, is is a logical and very relatable context for students. I use epic story problems along side a prop to allow students to experience changing numerators and denominators for themselves. An epic story problem may take a good 30 minutes and is really more like a play. I might start out by picking a student and saying something like <i>"Julie woke up this morning and found that her mom had left her a chocolate bar with a note that said "Have a great day!"</i> I would have the student come over and hold the chocolate bar. "<i>Julie began walking to school and saw her friend Frank. Because Julie is SUCH A NICE FRIEND she shared the chocolate bar equally with Frank. Now Julie and Frank each have ______ of a chocolate bar." </i>I would have Frank come up to the front of the room and they would break the chocolate bar into 2 equal pieces each holding a half. I would continue this story, "<i>Julie and Frank came across Tanya and Priscella and, because they are SUCH NICE FRIENDS they decide to share the chocolate bar equally with them as well!" </i><br /><i><br /></i>You can see where I am going with this story. I always made a big play of sentences as "such a nice friend" and the whole class would say the line together like some sort of strange game show. I guarantee that if you try this strategy engagement will be high in your classroom. Just be sure to chart your findings as you go so that you have a record to debrief and talk about during and after the lesson.<br /><br />If you really want to go for it, you can turn the story around and have students deciding that they don't want to each chocolate and giving their portion to another friend. You will be able to work in adding unit fractions and comparing fractions with the same numerator in this way. Your students really won't think of this as "fraction work" until you chart the numbers to match because the context is so natural. This type of work helps to build the "right" kind of natural connections between what your students know and what you would like them to understand.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-YNjw_E5gmLg/WLxIfsrt0qI/AAAAAAAAEY8/k9qv9S9qm2YG5w2mW6d12xkySysguaebACLcB/s1600/Rulers.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://2.bp.blogspot.com/-YNjw_E5gmLg/WLxIfsrt0qI/AAAAAAAAEY8/k9qv9S9qm2YG5w2mW6d12xkySysguaebACLcB/s640/Rulers.png" width="640" /></a></div><div class="separator" style="clear: both; text-align: left;">Rulers are another natural application of fractions. I love to use rulers that have specific fractions marked out on them and to work up to full rulers over time. Through School Specialty you can order rulers marked only to the inch, separate rulers marked to the 1/2 inch, and other rulers marked to the 1/4 inch. I have a link listed below so you can check them out but I am quite positive I didn't pay as much as Amazon is asking so I would shop around if I were you! </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">If you are teaching comparison of fractions on a number line, rulers are a concrete first step you can take. They take the principal of a number line and put it into a context that students are familiar with. I would talk about the different rulers and ask students to think about what labels might go on each of the different rulers and how they would label those rulers. </div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: left;">Another option is to take overhead projector pages - I'm sure you have some in a closet somewhere ;) - and to create a ruler with only inches marked, another with 1/2 inches in a different color, another with 1/4 inches in a different color and so on. You can then layer these rulers on top of one another so students can see how the full ruler is constructed. </div><div class="separator" style="clear: both; text-align: center;"><a href="https://4.bp.blogspot.com/-adAIxN7UgBQ/WMh_ecugOXI/AAAAAAAAEfU/mLqiRRTigWk29aV4D9p5HOmHbcvsSOiVACEw/s1600/Paper%2BClips%2B%25283%2529.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://4.bp.blogspot.com/-adAIxN7UgBQ/WMh_ecugOXI/AAAAAAAAEfU/mLqiRRTigWk29aV4D9p5HOmHbcvsSOiVACEw/s640/Paper%2BClips%2B%25283%2529.png" width="640" /></a></div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: center;"></div><a href="https://3.bp.blogspot.com/-YDwd5TZnjkw/WLx8CQmQ2yI/AAAAAAAAEZY/bJ1AaCrnh1wYJlUbXYpKjOjPBitY1YQxQCEw/s1600/Comparing%2BFractions%2BTangrams.png" imageanchor="1" style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="200" src="https://3.bp.blogspot.com/-YDwd5TZnjkw/WLx8CQmQ2yI/AAAAAAAAEZY/bJ1AaCrnh1wYJlUbXYpKjOjPBitY1YQxQCEw/s200/Comparing%2BFractions%2BTangrams.png" width="200" /></a> Pattern blocks can be used much in the same way as the variety of fraction bars listed above. In fact, I would use them in almost exactly the same way that I described using Cuisenaire rods. In my next post I am going to talk about how to link these concrete models to representations in an effort to move towards more abstract and fluent thinking, but I will make the point now that pattern blocks are an easy tool to use to begin to make this transition because students can use pattern blocks to represent a comparison (one whole built with 1/2 pieces vs. one whole built with 1/6 pieces) and they can then trace those pieces to show their representation.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-VeHh8HUalVw/WLxIfipVDzI/AAAAAAAAEY4/keU-17ZmdisYfMKXi-UZ7VvtwAMYzjnRwCLcB/s1600/Paper%2BClips.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="80" src="https://2.bp.blogspot.com/-VeHh8HUalVw/WLxIfipVDzI/AAAAAAAAEY4/keU-17ZmdisYfMKXi-UZ7VvtwAMYzjnRwCLcB/s640/Paper%2BClips.png" width="640" /></a></div> I will touch on paper clips only briefly because they are the least connected fraction model, however, you can promote an understanding that it takes fewer large paperclips to fill a space than it does small paper clips. This understanding is found within a second grade geometry standard that I have <a href="http://www.k5mathspot.com/2015/02/fly-on-math-teachers-wall-fractions.html" target="_blank">written about here</a>. <-- That post also includes a free 2nd grade math activity that may be useful if you are a 3rd grade teacher just starting your fraction unit. This may be an unnecessary model if your students are able to grasp an understanding that lower denominators yield larger pieces, however, it is a tool to use if you have any students who still can't quite make that connection for themselves!<br /><a href="https://1.bp.blogspot.com/-LUz7n3yluIk/WLx8Ev7NG0I/AAAAAAAAEZc/kmX3hA5ZKZ0vyv_jhv4nJJUF9GAVmWaawCEw/s1600/Fraction%2BCuisenaire%2BRods.png" imageanchor="1" style="clear: right; float: right; margin-bottom: 1em; margin-left: 1em;"><img border="0" height="200" src="https://1.bp.blogspot.com/-LUz7n3yluIk/WLx8Ev7NG0I/AAAAAAAAEZc/kmX3hA5ZKZ0vyv_jhv4nJJUF9GAVmWaawCEw/s200/Fraction%2BCuisenaire%2BRods.png" width="200" /></a><br /><br />The concrete tools that can be used to model fractions for comparison are really endless. The main <br />takeaway here is that these models are so very necessary to build strong anchors for your students. So, what can you do now that these anchors are built?

But, never fear, because if you can predict it, you can prevent it. If you know your student will think that an eighth is larger than a third because 8 is bigger than 3 we just need to be sure that you are being strategic in your instruction and getting out ahead of these predictable misconceptions.</span><br /><span style="text-indent: 0.5in;"><br /></span></div><div class="MsoNormal">These common errors, so often, are born out of the idea that students are handed <i>numbers</i> and asked to reason with them. They draw from what they know the best. And in this case, students have spent the vast majority of their primary years working with whole numbers. When third grade rolls around and students are asked to compare these fractions it is entirely understandable that they draw on their knowledge of whole number comparisons. Who could blame them? <o:p></o:p></div><div class="MsoNormal"><br /></div><div class="MsoNormal">It is then imperative that we consider methods of building understanding of fractions and comparison for students before they overgeneralize and draw their own “connections” that are doing little more than building confusion. Using the concrete, representative, abstract model for instruction you can build understanding in the concrete and representative stages and slowly fold in opportunities for abstract thinking. Students will then have anchors in their concrete and representative work to pull from rather than drawing on whole number generalizations. <o:p></o:p></div><div class="MsoNormal"><br /></div><div class="MsoNormal">The concrete, representative abstract (C-R-A) model calls for instruction to be built from concrete hands-on experiences, linked to visual representations and ultimately these experience allow students to generalize their understanding through purely numeric or mental work. </div><div class="MsoNormal"><o:p></o:p></div><div class="MsoNormal"><br /></div><div class="MsoNormal">So what, exactly, will the C-R-A framework look like at each step of the way? Follow me into the next three posts of this comparing fractions series. We will look to the 3rd and 4th grade fraction comparison standards and the most effective and efficient ways to promote understanding. <br /><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions-four.html" target="_blank">Post 1: The Math Spot Compares Fractions- Introduction</a><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions.html" target="_blank">Post 2: The Math Spot Compares Fractions- Comparison Tools</a><br /><a href="http://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions_9.html" target="_blank">Post 3: The Math Spot Compares Fractions- Representative Models</a><br /><a href="https://www.k5mathspot.com/2017/03/the-math-spot-compares-fractions_12.html" target="_blank">Post 4: The Math Spot Compares Fractions- Abstract Thinking</a></div><br /><div style="text-align: center;"><div class="separator" style="clear: both; text-align: center;"><a href="https://2.bp.blogspot.com/-c7NJQIXls8w/VzcbEKvXhII/AAAAAAAAIgQ/QeUVKZ3VCwwtLDo9-Ol9_3ckjdzU6gHegCPcBGAYYCw/s1600/signoff.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="92" data-original-width="245" src="https://2.bp.blogspot.com/-c7NJQIXls8w/VzcbEKvXhII/AAAAAAAAIgQ/QeUVKZ3VCwwtLDo9-Ol9_3ckjdzU6gHegCPcBGAYYCw/s1600/signoff.png" /></a></div><br /></div><!-- Begin MailChimp Signup Form --> <br /><div id="mailchimp"><form action="//k5mathspot.us13.list-manage.com/subscribe/post?u=4b7c3426552111fed54c8f2d7&id=c0c9055c1f" class="validate" id="mc-embedded-subscribe-form" method="post" name="mc-embedded-subscribe-form" novalidate="" target="_blank"><div id="mc_embed_signup_scroll"><h4 style="text-align: center;"> Research Based Strategies </h4><h4 style="text-align: center;">& Exclusive Freebies In Your Inbox</h4><div style="text-align: center;"><input class="" id="mce-FNAME" name="FNAME" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="text" value="First Name" /></div></div><div style="text-align: center;"><div style="text-align: center;"><input class="required email" id="mce-EMAIL" name="EMAIL" onblur="if(this.value=='')this.value=this.defaultValue;" onfocus="if(this.value==this.defaultValue)this.value='';" type="email" value="Email Address" /></div></div><div class="clear" id="mce-responses"><div class="response" id="mce-error-response" style="display: none;"></div><div class="response" id="mce-success-response" style="display: none;"></div><!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups--> <br /><div aria-hidden="true" style="left: -5000px; position: absolute;"><div style="text-align: center;"><input name="b_4b7c3426552111fed54c8f2d7_c0c9055c1f" tabindex="-1" type="text" value="" /></div></div><div style="text-align: center;"><input class="button" id="mc-embedded-subscribe;" name="subscribe" type="submit" value="Sign Me Up!" /></div></div></form></div><!--End mc_embed_signup-->The Math Spothttp://www.blogger.com/profile/09845707996634790905noreply@blogger.com0
