I'm a retired physics teacher working as a long-term sub for pre-calculus and intro. statistics. In physics, good pedagogy means having students engaged in labs and activities. What kinds of activities do math teachers use? #iteachmath

I’m a retired physics teacher, but I’m subbing as a math teacher for a few months. Pre-calculus and Introduction to Statistics. Looking for activities (maybe Desmos? Algebra tiles?). Can someone point me to an #iteachmath group?
