When Sir Cumference and Lady Di of Ameter invite two bakers to compete for the honor of baking the annual Harvest Sweet, the bakers must figure out a way to chart whose treats are the favorites. Illustrations.
Join Sir Cumference and the gang for more wordplay, puns, and problem solving in the clever math adventure that introduces readers to charts and graphs through an annual bake-off.

Sir Cumference and Lady Di need a baker to prepare a special dessert for the annual Harvest Faire. Two bakers compete to see whose dessert is most popular. When Pia of Chartres and Bart Graf have trouble keeping track of the votes their desserts receive, they each develop a better system. Pia places a colored candy around the edges of a pie dough (like a pie chart), and Bart stacks up cookie tins (making a 3D bar graph). When there's a tie, the two chefs cook up a hybrid dessert just in time for the Faire. Puns--both literal and visual--abound in this fun adventure story with beloved characters and a solid pedagogical foundation.
