Desmos Puppy House

By Fawn | Published: May 14, 2015

We don’t cover quadratic in Math 8 this year, so we really can’t do Des-man. I come up with “Puppy House” instead so my students can still create something that allows them lots of practice with writing linear equations with domain and range restrictions. They draft the house on paper. The house needs to have a minimum of 6 […]

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 […]
