Looking for a Decomposing Fractions Worksheet?

Have your students mastered their understanding of what a fraction is? If so, they are likely ready to move on to the concepts of composing and decomposing fractions.

So what does it mean to compose and decompose a fraction?

  • Composing a fraction means grouping together a collection of smaller fractions to create a larger fraction.
  • Decomposing a fraction means breaking a fraction down into a collection of smaller fractions.

This set of four worksheets will provide your students with the opportunity to compose and decompose fractions in a variety of different ways. The basic premise of each worksheet is outlined below:

  • Composing Fractions Worksheet 1 – Students use the picture models to determine the fraction that is shown.
  • Composing Fractions Worksheet 2 – Students use the number sentences shown to compose a fraction.
  • Decomposing Fractions Worksheet 1 – Students draw and color a circle to model the fraction shown.
  • Decomposing Fractions Worksheet 2 – Students write a fraction sentence made of unit fractions to decompose the fraction shown.

These composing and decomposing fractions worksheets download as a printable PDF or editable Google Slides file. Answers are also included in the download.

Vary the Delivery of These Composing and Decomposing Fractions Worksheets

When it comes to worksheets, it can be tempting to just print them out, photocopy them and distribute them to students. But there are alternative ways to incorporate worksheets into your teaching! Here are a few ideas to get you thinking:

  1. Math Stations  – Place a few copies of each worksheet at different math stations around the room. Worksheets can be placed inside reusable sleeves so they can be wiped clean with the arrival of each new group.
  2. Peer Teaching – Pair students up and give each pair a worksheet to complete together. One student acts as the “teacher,” explaining concepts and guiding their partner through the worksheet, while the other student takes on the role of the “learner,” asking questions and seeking clarification.
  3. Group Trivia – Divide the class into teams. Each worksheet becomes a different trivia “round.”  Students work collaboratively on each worksheet, then submit them for marking. The team with the most correct answers is the winner!
