The eighth book in the popular Sir Cumference series, SIR CUMFERENCE AND THE OFF-THE-CHARTS DESSERT introduces readers to different methods of collecting data.

Sir Cumference and Lady Di of Ameter are in a pickle. The castle cook is sick and the Harvest Faire is coming up-who will make the special dessert for this annual event? Two bakers in town, Pia of Chartres and Bart Graf, are up to the task. But after sampling Pia’s delicious pies and Bart’s scrumptious cookies, Sir Cumference and Lady Di just can’t choose! They come up with a solution- hold a contest and let the townspeople choose the dessert to be served at the faire.

When Pia and Bart’s methods of tracking their votes fail, they each realize they need to come up with a better system. Pia places a colored candy around the edges of a pie dough and Bart stacks his cookie molds-each color candy or mold shape represents a different kind of pie or cookie. Thus, the pie chart and bar graph are born! But when the contest ends in a tie, Pia and Bart concoct a hybrid recipe that everyone enjoys.
