Join Sir Cumference, Lady Di of Ameter, and their son Radius for wordplay, puns, and problem solving in this angle-packed math adventure. In the third installment of the beloved Sir Cumference series, Radius must prove himself on his quest for knighthood by rescuing a king. Sent off with the family medallion for luck, Radius dodges dangers and dragons. The ultimate challenge lies in a mysterious castle with a maze of many angles.
More than anything, Radius wanted to be a knight. Every day, he practiced riding, sword fighting, and archery. His teacher was the brave old Sir D’Grees. One day, Radius’s parents, Sir Cumference and Lady Di of Ameter, came to watch his lessons. “Show us what you have learned,” they said. In the riding ring, Radius mounted his horse and Sir D’Grees gave directions. “Knightly right angle – trot!” shouted Sir D’Grees. Radius rode his horse at a trot to the center of the ring and made an exact right angle turn. It formed a perfect corner.
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.
