Sir Cumference, Lady Di Ameter, and their son Radius appear in three fun math adventures. In the first book, The Circumscribers might be preparing to make war on the kingdom of Sir Arthur. In this clever tale, the author weaves a description of basic mathematical shapes into an interesting plot that teaches important circle terms and concepts, such as: radius, diameter, area circuference and more. In the second book, a potion has changed Sir Cumference into a fire breathing dragon. Can Radius change him back? Join Radius on his quest through the castle to solve a riddle that will reveal the cure. It lies in discovering the magic number that is the same for all circles. Book three has Sir Cumference helping Sir Vertex seek the sword in the cone. King Arthur has hidden his sword, Edgecaliber. The knight who finds it will be the next king.

Cindy graduated with a BA in International Studies from Willamette University and earned an MA from Stanford University. She has taught all grades in elementary school as well as high school.
Cindy began writing books in 1994. She had used math literature with her own classes in the early 1990’s and liked the way students responded to it. She wanted to use more of these books but found there were not many available so she started writing some of her own. Her books are published by Charlesbridge, Henry Holt, and Scholastic.
