Join Sir Cumference for wordplay, puns, and problem solving in this entertaining, medieval math adventure story about radius and the number Pi.

This time the math adventure is centered around a potion that changes 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.

The second in Sir Cumference series, Sir Cumference and the Dragon of Pi makes math fun and accessible for everyone.

Sir Cumference and his son, Radius, sat in the shade of a tree, enjoying a delicious midday meal. Partway through the lunch, Sir Cumference grabbed his stomach and doubled over in pain.
“Ooooh, my belly!” he wailed. “It feels like fire! Radius! Run to the castle. Find the good doctor and get me a cure.”

Cindy Neuschwander is a native Californian born in San Diego. 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.
