Sir Cumference and the Great Knight of Angleland

Sir Cumference and the Great Knight of Angleland by Cindy Neuschwander, ill. by Wayne Geehan



Genre: Math

This book in the Sir Cumference series focuses on the son of Sir Cumference and Lady Di of Ameter, Radius.  (The book is heavy with puns, and kids will love that!)  Radius has a dream of becoming a knight, and after a time of training he goes on a quest to find a missing King.  Radius uses his trusty protractor, a relic given to him by his parents, to solve puzzles and rescue King Lell.  The book is wordy and would be more appropriate for fourth or fifth graders.  The book was cute and I think math-lovers would really enjoy it.

Lesson idea:  In the book, Radius has uses his knowledge of degrees and circles to solve puzzles.  I think it could be fun to turn this into an interactive story, and have the students pretend to be Radius and solve the puzzles.  They could have their own "relic" protractors and solve puzzles to find the missing King--and perhaps a piece of candy, as well.
