Lesson objective: Apply understanding of three-dimensional shapes and their attributes.

This lesson provides an opportunity for students to apply their knowledge and understanding of three-dimensional shapes to a real-life situation. Students are asked to construct a city of 5 buildings using toothpicks and clay using given directions.

Key Concept students will use:

- Model shapes in the environment by building them from components (toothpicks, clay,etc.)

Skills students will use:

- use attributes to describe three-dimensional shapes (Kindergarten, Unit 5)
- compose three-dimensional shapes out of two-dimensional shapes
- build three-dimensional shapes out of components (clay and toothpicks)

Students engage in Mathematical Practice 4 (Model with Mathematics) as they construct buildings out of toothpicks and clay to represent three-dimensional shapes
