As part of this STEAM activity, kids can put their math knowledge to the test and discover the Pythagorean Theorem at the same time as young Pythagoras. Pythagoras follows his curiosity all the way to Alexandria, where he meets a builder by the name of Neferheperhersekeper. Neferheperhersekeper is the one who teaches Pythagoras about the right angle. Pythagoras uses geometry to teach himself how to measure angles and finds out everything he needs to know about right triangles while he is working on a building. Ellis’s book is the ideal STEM/STEAM resource for introducing young readers to a fundamental mathematical equation. He does this by peppering the text with humorous puns and wordplay. A pleasurable and approachable method for provoking the question “what’s your angle?” in the minds of younger people.
