Lesson 15

Build and Count with Solid Shapes

Lesson Purpose

The purpose of this lesson is for students to build with solid shapes to reinforce counting and comparing concepts.

Lesson Narrative

In previous lessons, students built with solid shapes and described what they built. In this lesson, students create towers, which requires them to consider the attributes of shapes as they determine which shapes stack easily.
