Sir Cumference and the Viking's Map: A Math Adventure

(4) 4-6 Illustrated by Wayne Geehan. Cousins Per and Radius hunt for treasure by unraveling a Viking mapmaker's clues: a series of coordinates (x, y) that pinpoint locations on the Viking's map grid. Highway robbers, channeling the Keystone Kops, chase the cousins around, but this subplot comes off as rather superfluous. Acrylic paintings with a medieval setting illustrate this introduction to coordinate (a.k.a. Cartesian) planes.
