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.

A Call for a New Alphabet

Jef Czekaj (author, illustrator)

Publisher: Charlesbridge ISBN: 9781580892285

Get ready for an alphabet revolution! X is exasperated. Every other letter in the alphabet has so much to do and plays such important roles in making words. X expects more. He calls for a vote on a new alphabet (gasp!). According to the Alphabet Constitution, X has every right to question the status quo. But the night before the vote, X is plagued by dreams of what could happen if he were to take on another letter's job. S has to run around a lot making singular words plural, except sometimes he isn't needed at all, and sometimes he needs to bring along another letter... it was all very confusing. Then X thought he'd like to be E. E was very important and very useful. E agreed. But E was exhausted. He was in thousands of words and constantly busy. X didn't think E's job was a good idea after all. Jef Czekaj explores the order of the alphabet and the rules of spelling and grammar with hilarious consequences. His graphic-novel-style illustrations make these concepts and the story of X exciting, exhilarating, and extraordinary.
