# Lesson 12

More than One Way to Make a Shape

### Lesson Purpose

The purpose of this lesson is for students to put together shapes in multiple ways to form larger shapes.

### Lesson Narrative

In previous lessons, students filled in puzzles using pattern blocks. In this lesson, students notice that there are multiple ways to put together pattern blocks to make a shape as they fill in more complex puzzles. They begin by filling up a pattern block puzzle that doesn’t show the individual shapes, which requires changing the orientation of shapes. Then they create the same shapes using different pattern blocks. Students should have access to pattern blocks throughout the lesson, including during the lesson synthesis.
