This is a lesson/assessment unit. It has many teacher resources. Detailed lesson plans, student worksheets, ppt, and suggestions on misconceptions. It is addressing 8.G.6 and 8.G.7. - proving Pythagorean Theorem and finding missing side lengths using Pythagorean Theorem. I think students will need more time understanding how to use the dot grid paper and on drawing tilted squares.
