# Lesson 10

Fracciones equivalentes

### Lesson Purpose

The purpose of this lesson is for students to see that different fractions can be equivalent if they are the same size of the same whole.

### Lesson Narrative

Previously, students were introduced to unit fractions and non-unit fractions using area diagrams, fraction strips, and number lines. They began to work with the idea of equivalence by noticing fractions that are also whole numbers. Here, students revisit area diagrams and fraction strips to learn about fraction equivalence. Students learn that fractions that are the same size are **equivalent** **fractions**. Later, they will identify equivalent fractions as having the same location on a number line.
