My Made4Math submission is inspired by some tutoring I did before our End of Course Exams for Algebra 1. We had students working on an online practice test, and they struggled when it came to a problem where a formula could be used. I found I kept saying "Use the right tool for the job." When I get back to school and have access to the butcher paper, I will making these much larger.
These are the rough sketches. I will have a toolbox at the top, and each time we cover a new concept (or review one).
