What would you do if the neighboring kingdom were threatening war? Naturally, you'd call your strongest and bravest knights together to come up with a solution. But when your conference table causes more problems than the threat of your enemy, you need expert help. Enter Sir Cumference, his wife Lady Di of Ameter, and their son Radius.

Editorial Reviews:

School Library Journal

One of King Arthur's knights attempts to design a table around which all of the knights can sit. With his wife, Lady Di of Ameter, and his son, Radius, Sir Cumference experiments with different shapes. Finally, a fallen tree inspires a round table. Geehan's illustrations , particularly the diagrams, help readers understand the geometry. Sir Cumference and the Dragon of Pi , Sir Cumference and the Great Knight of Angleland, and Sir Cumference and the Sword in the Cone provide similarly playful introductions to additional topics.


Students already familiar with shape principles will get the most out of this punny medieval story in which Sir Cumference, his wife Lady Di of Ameter, and their son Radius try to help King Arthur create the perfect table for his knights. Other Sir Cumference titles deal with angles, the number Pi, and three dimensional shapes.
