She received a BA in international studies from Willamette University and an MA in education from Stanford University. She has been teaching since 1975, both at the high school and elementary levels. As a mathematics education specialist, Cindy sought ways to make math fun, interesting, and comprehensible to her students. In 1992, while living in England, Cindy began working on her first book with this goal in mind. Sir Cumference and the First Round Table took five years to reach publication, but it remains a very popular book for its presentation of math concepts as well as for its amusing and exciting story. It has been followed by further adventures of Sir Cumference and his family, including Sir Cumference and the Dragon of Pi, Sir Cumference and the Great Knight of Angleland, Sir Cumference and the Sword in the Cone, and Sir Cumference and the Isle of Immeter. Cindy speaks at conferences often about writing, mathematics, and being an author. In her spare time, when she isn't writing or dreaming up new math adventures, Cindy enjoys activities with her family. The entire Neuschwander clan has spent time on five of the earth's seven continents. Only Australia and Antarctica remain to be visited. Cindy lives in California with her husband and two sons.

Read an Excerpt

“Another great harvest day! But wait—who’s that?” asked Edmund Rounds, the castle steward. He pointed to a few small tents just visible among the trees.
            “It’s probably travelers bedding down for the night,” answered Sir Cumference.
            Just then the steward’s son bounded up the stairway.
            “Ah, Rounds 2, keeping track of everything in the castle?” asked Sir Cumference with a smile.
            The boy nodded. Everyone called him Rounds 2, since he and his father were both named Edmund.
            “Papa, I’ve finished the counts you asked for,” he said, handing his father two scrolls. As the castle’s next steward, Rounds 2 was his father’s assistant.
            “Wonderful!” exclaimed Steward Rounds. “Let’s look these over during supper.”

Editorial Reviews

This latest series installment uses stories involving a knight named Sir Cumference as jumping-off points to explore mathematical concepts tackles rounding. Edmund Rounds and his son, Rounds 2, are responsible for keeping an inventory of items at Sir Cumference’s castle. When Rounds 2 hands over his latest counts for inspection, Edmund notices that the number of bread loaves and butter pots has not been totaled. Rounds 2 admits that adding is the difficult part. As they total the items together, he finds that it is much easier to calculate numbers in groups of 10 (10, 20, 30, etc.). His father tells him that for some items, such as the number of bees in the hives, it’s acceptable to come up with an approximate number. To thank his father for his assistance, Rounds 2 sets off to count the bedding of some travelers passing by but discovers that the men are enemies intent on attacking the castle. As Sir Cumference prepares for battle, he asks Rounds 2 to retrieve the bow and arrow counts. While these items have been counted, they have not yet been totaled, and Rounds 2 is left to complete the calculations himself. By rounding up or down to the nearest 10, Rounds quickly completes the task in what soon becomes known around the castle as the Rounds 2 Method. VERDICT Complete with the illustration style and subtle puns expected of the series, this title will be enjoyed by fans of the previous books.
