This activity works best with students in groups of 4. Groups designate a Person A, B, C, and D. Each slide has 4 similar problems. Each students does the first step of their problem. Everyone passes their problem to the left. They must first check the step done by the person before them. Then they complete the next step. This keeps going until the 4 problems are complete.
All equations have a variable on one side. I've included a few more basic problems at the beginning but the later problems focus on equations my students always have the most trouble with (fraction, distributing).
Instructions for the students are on the first slide.
