Over the years, I've compiled 25 printable PDF math reference sheets in this post -- all free. Most are for algebra and algebra 2. Some have videos to go along with them, and I have been planning on making more (goals). The math cheat sheets are free because I made many of them for my own inclusion algebra 2 students who needed reminders of the steps in the different processes we were learning in class. I hope the sheets are helpful for your math students, too! More at scaffoldedmath.com
