Group students into teams of five and pass out one copy of the same worksheet to each group. Have the group cut apart the worksheet so each question is on a separate strip or 'card.' Students then place the stack face down and choose roles (to be Person 1,2,3,4, or 5.) Explain how the activity is played and write the following team roles on the board for class reference: Person 1 on each team chooses a card and reads the question or problem aloud to the team. Person 2 paraphrases the question and/or offers clues to the answer. Person 3 says the answer and explains his or her thinking. Person 4 explains why he or she agrees or disagrees. Person 5 places the question card in one of two piles, Agree or Disagree, and then takes on the role of Person 1 for a new 'round' of play and reads the next question. (Person 1 now becomes Person 2, and so on. Because there are an odd number of people on each team, the roles–1,2,3,4 and 5–will shift for each question so that everyone gets a turn to play each role.)
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.
