Lesson objective: Build three-dimensional shapes to represent items in the real world.

This lesson helps to build procedural skills with three-dimensional shapes. Clay and toothpicks are used here because they allows students to physically construct the shapes. This work develops students' understanding that we can model shapes in the environment by building them from components (toothpicks, clay, etc).

Students engage in Mathematical Practice 4 (Model with Mathematics) as they construct and build the candy boxes using the attributes given.
