I also played a form of Twister on the floor to help them. We went through together labeling the X axis, y axis, origin, etc. on the taped off grid. After everyone had a turn to stand on a pair of coordinates, we played tic tac toe and battleship. Tic tac toe is where students have a grid, and one person is X and one person is o. They have to try and get 4 points in a row, but they have to say the ordered pair before they can claim it. They loved Battleship and it really got them thinking about graphing coordinate points!
