Sir Cumference

For fans of the Sir Cumference series with coordinate geometry on their mind, here is the seventh installment in this fun look at math and language.

While riding through the forests of Angleland, cousins Per and Radius realize they are lost and are desperate for a map to guide them home. Soon they come across a mysterious house in the hills. Inside they find a map to a treasure belonging to Xaxon Yellowbearyd, the fiercest Viking warrior of his time. Per and Radius must decode the strange numbered grid on the map, while trying to steer clear of the pack of bungling bandits who are on their tail. Will they find the treasure in time?

Cindy Neuschwander delivers yet another intriguing math adventure featuring the well-known characters of Angleland. Readers will enjoy following Per and Radius in their quest while learning how coordinate geometry relates to everyday life. Wayne Geehan’s beautiful illustrations offer a bit of comic relief, while also clearly demonstrating the concepts explored in the story.Cindy Neuschwander is an elementary school teacher who loves teaching math. She also enjoys traveling, reading, and writing stories. She thought up Sir Cumference while visiting medieval castles in England. Cindy lives in Pleasanton, California.“We’re well and truly lost,” Per said to her cousin, Radius. “How I wish we had a map.” They were riding through a forest in the late afternoon.
            “Maps of Angleland are as rare as dogs with wings,” replied Radius. “Maybe we’ll be able to see where we are at the top of that rise.”
            Together the two cousins rode up the hill.
            “What a view!” exclaimed Per. The landscape below them lay divided into four sections. A road ran across the countryside horizontally, while a river wound through the area vertically.
            “Hmm. Nothing looks familiar,” observed Radius. “And we’re running out of daylight. Let’s camp on that knoll tonight. The grass there looks thick and soft.”
