Students drew animals by mapping out ordered pairs and coordinate plane.

For young students stick with simple shapes with a minimum number of sides. If older students have not completed this project in early grades, you might wish to begin with simple shapes with them as well. Once students have mastered creating simple 3D shapes, have them create more detailed shapes. Start with hexagonal pyramids and prisms. Then move to shapes with more sides including octahedral pyramids and prisms up to icosahedrons.

Provide students with a chart of information and let them discover how to create the shapes. For example:
Icosahedron
5 triangles meet at each vertex
20 faces
12 vertices
30 edges
