# Lesson 7

Juntemos figuras planas

### Lesson Purpose

The purpose of this lesson is for students to compose larger shapes from pattern blocks and describe the shapes.

### Lesson Narrative

In previous lessons, students made composite shapes from three-dimensional shapes.

The purpose of this lesson is for students to compose shapes from smaller, two-dimensional shapes. They observe how the different pattern block shapes fit together to make larger shapes and how there are different ways to compose the pattern blocks to make the same shape (MP7). In the lesson synthesis, students reflect on what they have learned during their study of shapes in this section.
