Group students into pairs, and have them place their desks together in a way that forms a large circle in the classroom (or clearly-defined rows.) Pass out the assignment you want students to complete and have each person in the pair choose to be Partner 1 or Partner 2. Set a timer for an appropriate amount of time for each pair to complete the first question or problem in the assignment, then sound a signal to let all the Partner 2's know to move one seat down the row or clockwise while the Partner 1s stay in place. The new partnerships then work together to solve the next problem. Halfway through the assignment, announce that students should switch roles, and now the Partner 1s will rotate while the Partner 2s stay in place.
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.
