Lesson 12

Build Solid Shapes

Lesson Purpose

The purpose of this lesson is for students to build solid shapes from components.

Lesson Narrative

In previous lessons, students created solid shapes out of clay and described, compared, and sorted shapes. In the warm-up, students notice similarities between rectangular prisms and develop their own name for rectangular prisms. Box will be used as the example in this lesson. Students create solid shapes from connecting cubes and sticks and clay.
