So, this year, instead of just reviewing how to plug and chug with the Pythagorean Theorem, I decided I want them to re-discover (and thus re-learn) the Pythagorean Theorem. I set out on a virtual journey to find the perfect Pythagorean Theorem activity - one that shows kids WHAT they are doing when they use the Pythagorean Theorem, not just HOW to do it. I searched high. I searched low. The #MTBoS came to the rescue, as usual. I had happened upon Dan Meyer's Pythagorean Theorem discovery activity during a google search, but Lisa Bejarano's blog posts about it (HERE and HERE) helped me to re-think how it might be successfully implemented in my classroom. Jacqueline (@_Cuddlefish_) also sent along some really awesome links, especially an informal proof of the Pythagorean Theorem based on Perigal's proof of the Pythagorean Theorem (HERE).

I decided to re-work Dan Meyer's Pythagorean Theorem idea into an INB page that would provide a little more support for my students. It covers both the Pythagorean Theorem and its converse. Here is what I came up with:

I plan to still use the square blocks included in Dan Meyer's Pythagorean Theorem Discovery (HERE - Week 25), but I'm going to white out the area calculations and have students calculate those themselves.

I love when then MTBoS builds on each other's ideas in a sort of productive spiral! This is awesome and I can't wait to incorporate your adjustments into this lesson next school year.
