Grade 3-5–A fictionalized look (in spite of the CIP designation) at Pythagoras as he discovers his famous theorem. He is depicted as a curious boy who travels with his father from Samos to Alexandria, where he meets a builder named Neferheperhersekeper, who introduces him to the right angle. He begins to experiment, observing and noting the fixed and unvarying mathematical nature of triangles–right triangles, to be precise. The cartoon illustrations capture the dress, homes, and sailing ships in a warm and clear palette. Ellis includes delightful puns for those who are keen on wordplay. Sticklers be warned: there is lots of dialogue, but in the context of the story, it works well and helps to explain the math. This clear and interesting explanation of the theorem is a wonderful read.–Jennifer England, The Berkeley Carroll School, Brooklyn, NY
