As part of the traditionally high school course, Aaron (8th) is hard at work making a variety of different prisms, pyramids, and other polyhedral as he investigates the relationship between the number of vertices, edges and faces. If you look closely at the picture, you should see a regular tetrahedron, a cube, and a regular octahedron (or as regular as you can get with toothpicks and sour cherry balls.)
He then used the pattern he found (vertices + faces = edges + 2) to learn more about different octahedrons, heptahedrons, and dodecahedrons.
The lessons continue with the Geometry students finding surface area and volume of many different shapes, and concludes with finding the amount of cleaning solution required to clean the outside of the TransAmerica pyramid in San Francisco!
