Each student gets one or two cards with a question and an answer. Play goes around the room as students answer questions. This is a whole class activity. Includes the basic reciprocal, rational, Pythagorean, odd/even and complementary identities and a couple combinations thereof.
NOTE: If these cards do not exactly match your curriculum, cut the card pair(s) you want to eliminate in half and tape the halves you want to keep together before you laminate.
