# Exploring Equivalent Fractions

3rd grade

**Description**

Name fractions and develop an understanding of equivalent fractions using multiple models, including fraction strips, Cuisenaire rods, and number lines.

### Hook

Read aloud the book Fraction Fun by David Adler & Nancy Tobin.

Give students a paper plate and have them discuss how to fold the plate to show ½, ¼, and ⅛. Have them color ½ in one color, ¼ in another color and ⅛ in a third color. Tell them that this activity is just a warm up to the ideas. They will participate in 4 lessons that will give them more experience naming fractions and finding equivalent fractions. This will lead nicely into the engage for lesson 1.

### Lessons

Lesson 1 of 4

Create and use fraction strips to discover name fractions and compare two unit fractions.

Lesson 2 of 4

Use Cuisenaire rods to explore fractional relationships. This lays the foundation for work with challenging fraction concepts like equivalence.

Lesson 3 of 4

Students generate and explore equivalent fractions using Cuisenaire rods.

Lesson 4 of 4

Reason and develop an understanding of how to place equivalent fractions on a number line.

### ARC Assessement

There is an opportunity to assess if students can determine if two fractions are equivalent (equal) using multiple models, including fraction strips, Cuisenaire rods, and number lines, at the end of lesson 4 of this ARC. The assessment uses Cuisenaire rods and an activity sheet with a series of number line tasks. Students are asked to use Cuisenaire rods to generate number lines for halves, fourths and eighths, and determine which fractions are equivalent.
