Valerie's Math Class

This is the MOST successful lesson I taught because of the emphasis on conceptual learning. Students start with identifying opposite, adjacent and hypotenuse (pg 1). They practice pythagorean theorem to find the third side length. Pg 2 students measure side lengths and create ratios. Students next to each other have opposing investigations (1 and 2). They then compare their ratios and we talk about why we get the same ratio decimal even though side lengths are totally different - ANGLES! I then

I used this lesson after my investigation to go from making 6 ratios to making 1. Then we did notes on finding side length given an angle and a side length. The back is practice doing both types with key included. Great lesson- most successful one I have taught!
