Help students understand fractions with this fun-to-use math center! Students simply pick up a set of fraction bars, grab an activity sheet, and read the easy-to-follow instructions to get started! Perfect for independent learning, the center has enough for up to six students to work on at once. Students can also work in small groups for hands-on math-building practice!
What’s Included• Fractions center with a pouch and worksheet storage• 6 fractions pouches (each pouch contains fraction bars from one whole to 1⁄12)• Label card with directions• 24 reproducible activities
Before You BeginSet the materials on a table in your classroom. Next, place the fraction bars in individual pouches. Make sure each pouch has a set of fraction bars from 1⁄12 to one whole. Place the pouches in the designated compartments in the storage unit. Select a reproducible you would like students to complete and make enough copies for each student. Place the reproducible in the top tray marked “take one” and invite students to take turns using the materials and completing the activity. Be sure to tell students to return their completed activity pages to the “turn in” tray.
About the ReproduciblesThe center comes with 24 reproducible activities. There are eight activities in each of three levels: A, B, and C. The activities are designed to engage students in hands-on learning, reinforcing these essential math concepts.
Using the Math CenterThere are a variety of ways to use the center in your classroom. Whether you choose to use the center for small-group instruction, to reinforce prior learning by having students work in pairs, or to give additional practice to individual students, this center provides all the essentials to meet the needs of your students!For small groups of up to six children at a time, select an activity page from the skill area you would like to target and reproduce a copy of the activity for each child. Then provide each student with a fractions pouch. Work through several of the activities with students, modeling the strategies needed to solve each problem. Then invite students to use their fraction bars and work together to complete the remaining activities. Allow
2
students to discuss the problems as they work, sharing problem solving strategies and recalling their basic understanding of math concepts together.You may want to have students work in pairs to complete the activities. Make enough copies of the reproducible pages for each child to have her own, then ask partners to share fraction bars as they work on the activity together. Encourage them to share their thought processes as they complete the activity so that they can learn from one another.The center is perfect for reinforcing fractions concepts one on one! After students have completed other work, encourage them to select an activity from the “take one” tray, along with a fractions pouch, and invite them to take the items to their desks to complete the activity on their own. Once they are finished, encourage students to return the materials to the center and place the completed activity sheet in the tray marked “turn in” for you to check at a later time.
Meeting Individual NeedsELLIn a small group, distribute a set of fraction bars to each student. Display each fraction bar and call it out by its name (one-third or one-twelfth and so on). Create a reference chart with each fraction piece posted on the chart with its name labeled next to it. Using the chart, show how fractions are part of a whole and that students will be using the fraction pieces to help them complete their worksheets. Work on an activity sheet with students to make sure they understand what they need to do to complete a worksheet.
Reteach/Extra SupportMeet with a small group of students and work on a selected activity. For example, guide students through the “Fractions Schoolhouse” using the fraction bar manipulatives. Starting with #1 on the worksheet, find the levels on the schoolhouse that are divided into two equal areas and four equal areas. Additionally, have students find all of the 1⁄2 fraction bar pieces and 1⁄4 fraction bar pieces to use as models. Have them start with one 1⁄2 fraction bar piece and line up 1⁄4 pieces below the 1⁄2 piece until they are the same size. Students should see that 1⁄2 = 2⁄4 and that they should fill out the fractions number sentence for question 1. You may also choose to have them color in the appropriate fraction bars on the worksheet for a permanent visual model. Continue through each problem on the worksheet, using the fraction bar pieces to model the equivalent fractions.
In a small group, direct students to play with their fraction bars to show different ways of making a whole (such as eight 1⁄8 pieces make a whole). Afterward, show students all of the ways you can make one whole with the fraction bars included in the pouch. Place different fractions on a table so that they are lined up vertically so students can compare and see fractions greater and smaller than each other and how different fractions could equal the same value, such as 4⁄12 = 1⁄3.
ChallengeOn their activities, tell students you will only accept fraction answers that are in their simplest form. For example, 5⁄10 would only count as a correct answer if it was changed to 1⁄2. Have students create a Try This! section at the bottom of each worksheet with adding and subtracting fractions and/or comparing fractions. Introduce mixed numbers and improper fractions.
Informal Assessment IdeasThe 24 leveled worksheets provided in this guide can be used as an effective informal assessment of students.
• Create a schedule where students are responsible for completing one worksheet per week. Require students to answer all of the problems correctly on a worksheet before they can move on to the next worksheet.
• Keep students’ worksheets on file to see if there are any patterns to the problems they are having trouble with. The worksheets can be used as a record to help you decide to review, reteach, or spend more time on particular areas.
• Since the worksheets are leveled into three groups (low, medium and high), you can use a B (medium) activity as a baseline indicator. Depending on how students perform on that worksheet, you can have them start with the easiest activity (for the kids who need extra support) or assign them multiple worksheets to complete (for your students who need more of a challenge).
