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.In the eighth installment of this popular math adventure series, 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). Puns--both literal and visual--abound in this fun adventure story that introduces different methods of collecting data. Perfect for parent and teachers who are looking to make math fun and accessible for everyone.
