Neuschwander, Cindy Sir Cumference and the Off-the-Charts Dessert: A Math Adventure
Gr. 4–6   32 pp. Charlesbridge

Illustrated by Wayne Geehan. In this pain-free math lesson, two bakers compete to determine who will provide the official sweet for the annual Harvest Faire; each tries out different counting systems to keep track of the votes. The slapstick-scattered, medieval-set acrylics anticipate the pleasingly atrocious puns. (Who knew that baker Pia of Chartres originated the pie chart and baker Bart Graf the bar graph?)
