Brief Summary: Sir Vertex and Radius join the quest for King Arthur's sword Edgecalibur. To find it they must solve the King's riddle by finding the area of a cone.

Topics: geometric solids; cones; volume; Euler's Law

Suggested Activities:

Use Euler's Law on a variety of geometrical shapes (cubes, pyramids, rectangular prisms, and triangular prisms). Then have them bring any cone-like object in to class and find its area.

Have students compare and contrast the structures and implications of Euclidean and non-Euclidean geometric.

Have students explore 3 dimensional solids and have them describe them verbaally or in their math journals.
