This activity can be used to teach latitude and longitude or just plotting coordinates. Use a 10x10 grid, labeling the lines up from the bottom starting with A, B, etc.
Kids pair up, each with a grid of their own and five conversation hearts.
With a folder or barrier in between, they place their heart candies on the intersections of the lines. If they have, they take that heart. The object is to get all of your opponent's hearts. Assure the kids that they will get other candies to eat after the game that have not been handled by so many hands.
