This is a great quick review game for the AP exam or for your limits unit! Cut the cards up and pass out one card to each student in the row (the game is set up for a row of 5 but it can certainly be adjusted).
Student 1 will solve the limit question and write their answer on their card and pass it back. Student 2 will have to use Student 1's answer in order to solve the limit question.
When Student 5 receives the card, their final answer determines which group wins. If a student messes up in the process, it will make it impossible for the other students to evaluate the limits.
My students love this game and get very competitive with one another!
