Resources for Teaching Pythagoras' Theorem

I've decided to make the lesson plans, materials and such I write freely available under an Attribution, NonCommerical, ShareAlike license from Creative Commons.

The first lot of material I'm making available are the lesson plans for teaching Pythagoras' Theorem that I developed last semester (and wrote about using). If you're interested in teaching, mathematics, or teaching mathematics why not have a look at my free lesson plans.
