This is an intro activity to get students used to a graphing calculator. Students work in teams of 4. For 10 minutes they master 3 (or 2-4) squares on the sheet. After 10 minutes they split up. 2 students circulate the room learning how to do the rest of the boxes (get the box initialed so they know it is done) and 2 students stay at home base and teach the other students who come to them how to do the boxes they had previously mastered. After 15-20 minutes students go back to their original group and explain what they learned as they traveled the room.
