Sir Cumference and the Great Knight of Angleland
by Cindy Neuschwander
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. With a medallion at the back of the book readers can jump in the adventure and help Radius find the right angle.
