They said, “That just gives you area.” So I made these sketches, and hopefully the kids understood why finding area wasn’t the same as finding steepness. Those who did not do “base times […]

## Staircase and Steepness

AHHHH, I love how this lesson has turned out so far!! Today was our 3rd day of State testing, and because I have 8th graders for homeroom, we still have three more days of testing next week. Ick.
