If you're teaching your students to use a TI-84 or higher calculator to solve equations or systems of equations, you can use this step-by-step guide. I've used images from a TI calculator to help students find their way around easier. My students love this step-by-step guide! I've included 2 exact same pages so you can print 2 pages on 1 to create half sheets if you don't want a large sheet of notes. I printed half sheets to be taped in as notes and the whole sheet went on the word wall.
