King Arthur was a good ruler, but in this math adventure he needs a good ruler. Geometry is explained with humor in SIR CUMFERENCE AND THE FIRST ROUND TABLE, making it fun and accessible for beginners. 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. With the help of the carpenter, Geo of Metry, this sharp-minded team designs the perfect table conducive to discussing the perfect peace plan. Thanks to Sir Cumference, even the most hesitant will be romancing math.
"""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.""—School Library Journal ""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.""—Booklinks"
