Pythagoras for Kids
There are many resources available online for this lesson plan. I used this for kids 7 and up. It was also a great refresher for me. I remember learning the Pythagorean Theorum in school, but I was never told why I had to learn it or why it was important to know.

You will need:
1. The book: What's Your Angle, Pythagoras by Julie Ellis
2. Rope, twine, ribbon, or yarn to tie into knots.
