Sir Cumference
and the Sword in the Cone




by Cindy Neuschwander
illustrated by Wayne Geehan

A Sword in the Stone retelling, with a mathematical slant. King Arthur has promised that the first knight to find Edgecalibur the Sword will be the next king.  In taking up the challenge, the family discovers the secrets of cylinders, cubes, cones, and pyramids. Illustrations include details to help solve the mystery.

This book would be most helpful for students who are already a little bit familiar with cones, cylinders, cubes, and pyramids so that they can apply their knowledge and have an incentive to try and solve the riddle before or along with the characters.
