Use this set of worksheets to review students’ understanding of the relationship between the number of parts to the size of a fraction.

Learn About Fraction Size

When first learning about fractions, students typically learn how pieces are equal in size and are named with words such as halves, thirds, fourths, etc. As students work with fractions more, they will learn that the piece’s size correlates to the denominator. Simply put, the larger the denominator, the smaller the piece and the smaller the denominator, the larger the piece is.

Think about it this way, if you divide a pizza into quarters and eat one of those pieces, the size of that piece would be much larger than if the same pizza was cut into eighths.

To help students understand this concept, Teach Starter has created a set of worksheets to help your students solidify their understanding of this concept. This download includes 3 worksheets (one being a hands-on activity where students will manipulate pizza pieces) to explore the relationship between the number of parts and the size of a fraction. Students will follow the provided instructions by drawing and coloring a set of items to create a fraction of a set and answer questions about each.

An answer key is included with your download to make grading fast and easy!

Tips for Differentiation + Scaffolding

In addition to independent student work time, use this worksheet as an activity for:

Guided math groups
Lesson warm-up
Lesson wrap-up
Fast finishers
Homework assignment
Whole-class review (via smartboard)

For students who need additional support, consider providing them with fraction circles to investigate the difference in the size of pieces when the denominator changes.
