## Parts of Wholes or Sets

### Lesson Plan Reference

**Grade Level** 2-3

**Difficulty Level** 3 (Developing to Mastery)

**Type of Assignment** Individual, Partner, or Group

**Common Core Standards**

- [Math/Content/3/NF/A/1] Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.

The most important concept for beginning fraction masters is that of parts of wholes or parts of sets. Students see and hear parts and wholes in use daily, but representing those values numerically can be challenging. Begin first with shapes that have been divided up into equal shares (circles, squares, hexagons, etc.), and then once students have grasped the concept, move on to fractions of sets. Fractions of a set is a far more useful concept for world problems and real-world application.

One example might be:

** 1/4 of the class is 6 students, how many students are in the class?**

In this activity, students will create different examples of fraction sets by creating equal groups of simple shapes or objects and color coding the groups. There are many ways to modify "Fraction of Sets Starter" storyboard in order to meet the needs of your students. The starter template is intended to be used for students who need a lot of guidance. Make it more challenging by adding rows and/or columns, providing less guiding information in the description boxes, or having students choose the number and types of objects.
