Coordinate Grid Game with all four quadrates. Put students in groups of four. Each group needs a coordinate grid board. I used checked boards from the dollar store and added the x and y axis. Print out the cards on card stock and cut for each group. Students put the cards in the middle face down. Students work in groups if two. One group picks up a card and plots the points. The other group writes down the correct location of the points. If they get the correct location then they earn a point for each correct location. Then the other group picks a card and so on.
