Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

This math activity exposes early learners to a variety of three-dimensional objects. Learners bring geometric solids (everyday objects) from home.

In this activity, learners follow simple directions to explore and create platonic solids.

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.
