Meet Sir Cumference

It's a well-known fact that very few children's books cover the basics of coordinate geometry. But the U.S. Common Core Standards require fifth-graders to be able to graph points on the coordinate plane to solve problems. Just what can a conscientious librarian do to help solve that problem? Introducing the Sir Cumference series of adventures for grades 3-5. Sir Cumference and his wife Lady Di of Ameter are the King and Queen. Their son Radius is on a quest to become a knight, and all of his adventures require him to solve fun math puzzles (and involve lots of terrible puns). The titles are available to schools as well as public libraries, and the price is right, at only $6.99 each.
