Lesson 11

Generate Equivalent Fractions

Lesson Purpose

The purpose of this lesson is for students to generate equivalent fractions.

Lesson Narrative

In previous lessons, students learned what it means for two fractions to be equivalent. In this lesson, students continue to reason about and show equivalence visually, building on their work with fraction strips. They use shaded diagrams to help them generate equivalent fractions, including fractions greater than 1. The work here prepares students to use number lines to explain fraction equivalence later in the section.
