This is a 2 slide PowerPoint in which students use their knowledge of coordinates to play the game of Battleship. Students play with a partner each using their own computer. On slide 1 they are to slide the shape markers for each battleship placing them on their grid as their partners do the same. Slide 2 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. Good practice for coordinate geometry skills.
