Just how fabulous is Desmos. Following up on last Friday’s lesson, I had the kids create “Des-man” on Desmos. I made these very simple sketches, showed them to the kids, and told them the minimum requirements: face and mouth must be parabolas eyes and nose are linear equations Not only was this so great to reinforce slope, y-intercept, and all the coefficients, it also […]

Staircases and Steepness, Continued

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. I didn’t want to cram/review again with my 6th graders today, so I thought of doing a lesson on “steepness” (adapted from Swan […]
