In this math lesson, learners identify, describe, and construct the five regular polyhedra.

In this activity, learners discover how NASA engineers develop experimental aircraft.

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 explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.
