### Description

The lesson discusses decomposing fractions and will help your students gain a deeper understanding of fractions and how they function.  By breaking fractions down into smaller pieces – decomposing them – students will better understand how to work with these numbers as part of their math lessons.  The lesson also reviews vocabulary like numerator and denominator, as well as mixed numbers and improper fractions.  The lesson include an activity sheets that instructs students to create visual aides to help them practice using fractions.

### Classroom Procedure:

1. Begin by asking students if they know what the word ‘decompose’ means. Wait for responses.  Explain to students that decomposing fractions means taking apart fractions into smaller pieces.
2. While reading the content pages, reinforce vocabulary and give students additional examples of decomposing fraction problems in order to help them practice the new skill.  Use the additional resources to enhance understanding.
3. Introduce the notes on decomposing fractions. Have students practice problems with drawings.  Use the additional resources to enhance understanding.
4. Have students practice problems as a whole class so that they can fully grasp the concept.
5. Follow Activity page with students. Have students work in groups to try to stump the teacher.  Provide students with an incentive if they win the game.
6. Distribute Practice page. Check and review the students’ responses as a class.
7. Distribute the Homework page. Have students work a few problems at the beginning of the next class to reinforce the new skill.
8. In closing, ask students to explain the steps in how they think about decomposing a fraction.
9. Allow for responses and discussion.
