Product Description

From School Library Journal

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

3.0 out of 5 stars Unfortunate Anachronisms Dec 22 2004
By Jolene Gleason - Published on Amazon.com
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.

5.0 out of 5 stars Easy To Understand May 22 2008
By M. Bensh - Published on Amazon.com
Format:Paperback|Verified Purchase
I bought this book to read to my 6th grade math class. We had been working on perimeter and area and I was trying to explain the Pythagorean Theorem to them as an introduction to what they would see in 7th grade. Only the "math" minds were really able to get the concept, until I read them the book. The book goes into great detail using fantastic visuals that link well to the story. The kids loved it and many more said they were now able to understand the formula. I'm even planning on showing it to my 8th grade coworker - they were having trouble understanding it as well.

5.0 out of 5 stars Pythagoras made easy! Aug. 8 2004
By T Love - Published on Amazon.com
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!

5.0 out of 5 stars A Fun Way to Introduce Math Sept. 13 2008
By P. Kathleen Calkins - Published on Amazon.com
What's Your Angle, Pathagoras? is a great way to get students ready for math on a day when you aren't going to start with a computation drill. It is a pleasant, easy read and it not only explains the Pythagorean Theorem in easy to understand language and with pictures, but it also can be the starter to a discussion about possible careers in math. 'Tis a great book for students 3rd - 6th grade.

4.0 out of 5 stars it's a fun read Nov. 17 2007
By C. Hamilton - Published on Amazon.com
I teach high school math and read this book before vacation when the kids aren't keen on "doing math". They LOVE it, especially since they've been using the pythagorean theorem for years.
