This is a PowerPoint in which students use their knowledge of X/Y coordinates to play the game of Battleship. Students play with a partner each using their own computer. On the right side they are to slide the shape markers for each battleship placing them on their grid as their partners do the same. The left side is used for guessing and students place hit or miss markers on the grid. After students finish the game they can quit, don't save, and then play again. Fun way to practice for X/Y coordinate geometry skills.
