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.
- Engagement

Learning Goals
Teacher Facing
- Compose solid shapes to build new shapes.
- Count to answer “how many” questions about groups of up to 20 objects.
Student Facing
- Let’s build with and count solid shapes.
