The teacher needs to hang the equations and solutions in random order around the room. Hand out the answer sheet to each student. The student can pick anywhere to begin. They need to write where they start in the first solution spot. The student then solves the equation below it. Once they find the solution, then they need to go find it somewhere in the room. Once they locate it then they need to put that solution in the next spot on their answer sheet. They continue this process until they have come full circle.
