Lesson 2

Build Shapes from Other Shapes

Lesson Purpose

The purpose of this lesson is for students to use three-dimensional shapes to compose larger shapes. 

Lesson Narrative

In the previous lesson, students sorted three-dimensional shapes and used their own language to describe them.

In this lesson, students put together three-dimensional shapes to compose larger shapes. Students begin by using solid shapes to build any way they would like. They describe what they create and the shapes they used. Students then make three-dimensional shapes (prisms and cubes) from smaller shapes. Students do not need to use formal names for the three-dimensional shapes such as rectangular prism or triangular prism.
