Divide students up into teams of 4, and number them off so each person plays the role of Team Member 1,2,3, or 4. Ask a question from the worksheet and provide 30-60 seconds for each group to agree upon an answer. They should ensure every person on the team understands the reasoning, as they won't know which team member will be responsible for answering the question. Then, randomly call out a number between 1 and 4. The person on each team whose number was called writes his or her answer on an individual dry erase board (or sheet of paper). Team members can NOT help in any way, or they will lose a point. On your signal, the designated student holds up his or her board/paper to show the answer, and you (or a student volunteer) can award and record points on the board. When time is up, the team with the most points wins.
Have students stand in two rows facing each other. Choose a question or problem from a worksheet and read it aloud to the class. Give students 30-60 seconds to discuss their responses and reasoning with the person across from them. Give a signal for each student to then move one position to the right (the student without a partner at the end simply walks to the other end to find his or her new partner.) Continue playing until students have discussed all the questions. giving students an answer, and have them work with their partner to brainstorm possible questions/problems for that answer. Challenge students to complete the worksheet and make an intentional error (an incorrect math calculation, out-of-order sequencing, grammatical or factual mistake in a written response, etc.) Then have students switch papers, mark the mistake, and discuss it.
