Each student will be given a handout, either “Partner 1” or “Partner 2.” You may choose to have students pair up to begin, or solve first and then find someone who is the opposite to compare answers after. Once all six expressions are simplified, they will compare their answers with a partner. They had different expressions, but should have the same distributed expression after combining like terms Go down the list and put a check mark if they are both the same, put an x if they do not match. Then, go back to the ones with an x and switch problems. Do you get the same expression that your partner got before? At this point, the goal is for students to catch each other’s mistakes and agree on the correct expression.
