You can show the number 5, 102 in place value strips, have students create it with place value discs, and then write it in word form. Draw place value disks to show the numbers 1. Understand: Why this strategy works. After mastering the representational level, move on to the abstract level. Instead of thinking of it as "4 x 2 = 8, + 1 = 9" the discs are going to force students to use the place value. In the pictures, you can see how we underline the 13 and draw an arrow so students can see that 13 actually equals 130 because we technically have 13 tens.
Draw Place Value Disks To Show The Numbers 10
In fact, the one that they're "carrying" might not even have a value of one, it's likely going to be 10 or even 100! Rotate Counterclockwise. I love using the place value discs here because they are always showing the value. Usually, I like students to keep their decimal and whole number discs separate, but if you wanted students to have a combined kit and you want to streamline, you could probably get rid of your thousandths discs, and if you aren't adding within the 1000s, then could also get rid of those discs as well. We can also play with the idea of adding more to a place value in a decimal number. Let's start out with some basics! What are place value disks. They also learn from support and feedback as they move from concrete to abstract representations of a number. They'll put that 48 into groups, but they sure won't be equal. Using place value discs when teaching the traditional method helps keep students' focus on attending to place value instead of memorizing "shortcuts" like "carry the one".
Draw Place Value Disks To Show The Numbers 2
Have students work in pairs and one builds 398 with the place value strips, and the other builds it with discs. Then, let's build one and 46 hundredths (1. In the end, when we subtract it out, we realize that we have 10 and four tenths (10. They can see it, they can manipulate the discs and then learn to visualize the idea as well.

98), and added one more tenth, what would happen? Like with every activity, you can always go back and try doing this with drawing, having students show the same concept as if they're using the discs but showing it in a pictorial way to demonstrate their understanding. Students will build the first addend with a white ones disc, three brown tenths discs, and seven green hundredths discs, and then underneath, stacked like coins, they can put their eight tenths and five hundredths. In this case there is not a remainder. But don't let that keep you from increasing the complexity of this activity! Play games like Multiplication Speed and Multiplication Bump. 3–5 (Common Core Math Practice MP2: Reason abstractly and quantitatively; Common Core Math Practice MP5: Use appropriate tools strategically). Draw place value disks to show the numbers. Place value discs can be challenging to keep organized, so be sure to check out our Math Salad Bar video on setting up and organizing your place value discs so they can be student-ready when they're needed. They'll have a full 10-frame with two leftover. We can begin by combining the five tenths with the four tenths. Have students build six and eight tenths (6. 5 (Common Core Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left). This gives you a way to see their understanding of place value and the idea of "groups of". I think students do not get enough hands-on experience to really fluidly understand what they're learning with decimals before they're pushed into the traditional method of subtraction.
What Are Place Value Disks
Printable Place Value Manipulatives: Hundreds, Tens and Ones for Place Value Work and ModelingIncludes BOTH Modeling (Larger) and Student (smaller) sizes of:Place Value Blocks / Base Ten Blocks: Hundreds, Tens, OnesPlace Value Straws / Sticks & Bundles: Hundreds, Tens, OnesPlace Value Disks / 100, 10, 1Includes Blackline and Color Versions! We want them to create four circles, because we know that's how many groups we need. Modeling with Number Disks (solutions, worksheets, lesson plans, videos. Then, they can either create the number with place value strips, or write it in numerical form. Show groups of 10 with straw bundles (or other objects) to remind students of previous lessons. As we begin to add, we have seven hundredths plus five hundredths, which gives us technically a total of 12 hundredths. As they become more familiar with place value, maybe even by using the place value strips, students can use non-proportional means like place value discs to help deepen their understanding of place value. Model how to count 10 ones disks and then exchange them for 1 tens disk.
Draw Place Value Disks To Show The Numbers Lesson 13
Every time we make a move with the discs, we have to be sure to record that on the dry erase work area. For kids to play, as well as lots of other games which can immerse them in what division looks like. Explain that ten (or 10) refers to the number that is more than 9 but less than 11. Model how to put the place value disks on the place value mat to compose a four-digit number. When they see 10 tenths, for example, students often think that that means one hundredth, which makes sense to them if you think about adding 10, 20, 30, 40, 50, 60, 70, 80, 90, 100. So, we have to regroup. To represent this idea another way, count 10 ones, then write a sentence frame on the board: "____ ones disks make ____ tens disk. " If students have trouble drawing circles, they can trace a coin. We also have place value discs that represent decimal numbers – 0. Make sure you think through each example problem you give ahead of time so your students have enough discs to build it. Please submit your feedback or enquiries via our Feedback page. We put that four up there at the top of the algorithm because students will say, "Three goes into 13 four times. "
Draw Place Value Disks To Show The Numbers 5
It's also a little easier to forget about the value of numbers when they're adding together at the top, so having them at the bottom might help kids see things a little more clearly. So, again, we subtract 12 from 14 and we're left with the remainder, which will also be left with the discs. Now, we pick up that seven and, knowing we already have five discs, we take two additional discs from the ones place and we can subtract. We start by building the minuend with the discs and the subtrahend with the strips so kids can see how we're taking the 4. All of these activities and resources provide opportunities for students to really develop a foundation of understanding for division. Of course, they should also reflect the change with the place value strips. However, we want to make sure kids don't just ask, "How many times does four go into four? "
For example, if you write out the words five thousand one hundred two, students often struggle reading words, or maybe even speaking them clearly as to what the values are. Add an OpenCurriculum resource. They could draw circles for groups, or use bowls. It's a really great way for kids to prove that they understand the traditional method by attending to place value with decimals. It is essential that we do a lot of this kind of work before we move into using the place value discs. This is such a powerful way to help students actually understand division. We want kids to look at going the other way on the place value chart to see if they can figure out how to change four and two hundredths into three and 92 hundredths by taking away one tenth. Do a think-aloud as you model how to put the disks on the mat. These place value disks (sometimes called place value chips) are circular objects that each represent 1, 10, 100, or 1, 000. A former elementary teacher and a certified reading specialist, she has a passion for developing resources for educators. It can be a challenge to wrap your mind around, but slowing it down and acting it out can really help students see what they're doing. Experiment with 3-digit numbers and have students add 100 more.
