This is an activity for students. You will need to create two dice that contain like terms. I made one that had: x, 2x, -2x, 3x, -3x, and 4x. The other had: x^2, 2x^2, -2x^2, 3x^2, -3x^2, and 4x^2. Students will roll both dice twice. They will then record the results in the four boxes. Students will simplify by combining like terms and write their answer on the given line. They will repeat the process 3 more times. Last, they will complete the bottom of the worksheet.
