Pg 6. Right Triangle Basics (Optional - Used this my second year, but not my third.)
Pg 7. Pythagorean Theorem
LEFT: We took a square piece of paper and folded it until the entire square is made up of small right triangles. We then selected a right triangle and the three surrounding squares to demonstrate the Pythagorean Theorem.
RIGHT: Another time, we selected, drew, and then cut out the diagram to demonstrate the Pythagorean Theorem.
I have seen other diagrams using all the pieces to make a square, but I have yet to understand them or see the purpose. Any suggestions for enlightening resources?
Pg 8. Pythagorean Theorem and It's Converse
This next year, I will use Anglegs and worksheet to introduce and classify triangles.
My students came with excellent prior knowledge of the Pythagorean Theorem.
Pg 9. Multistep Pythagorean Theorem
