What's Your Angle, Pythagoras? A Math Adventure

Summary: Unfortunate Anachronisms
Review: This is generally a good book about the Pythagorean Theorem. I was disappointed, however, that someone did not catch the gross anachronisms before publication. In the book young Pythagorus travels to Alexandria, Egypt. However, Pythagoras was born (as the book points out) around 569 BC. This predates Alexander the Great by more than 200 years. Of course Alexandria would not have existed before Alexander the Great. Also as Pythagoras' ship approaches Alexandria, you can see the great lighthouse, one of the Seven Wonders of the Ancient World, in the background. The lighthouse wasn't built, however until around 271 BC - even after Alexander's death. I know it's just a fictional children's book, but come on. Our children deserve a little better research.

Summary: Pythagoras made easy!
Review: This is probably the most enjoyable way I have come across to teach Pythagorean Theorem to my children. It's one of those special books which children will read without realising they are learning a mathematical concept. Highly recommended to teachers and parents grappling with this sometimes difficult topic!
