This is a spinoff from the regular board game, Battleship. It's a fun way to practice plotting and identifying (x,y) coordinates in each quadrant of the coordinate plane. Students will play the game with a partner. They will begin by drawing six battleships on their own graph. Then they will take turns guessing points of their opponent's battleships on a separate graph. They will also keep track of their own coordinates as the opponent guesses them. The first person to sink all six battleships wins.
The game sheet comes with directions. You can print and make copies for each student. I like to give the students each a file folder to use as a way to cover the sheet. They can hold one side up while they are working to hide their graphs, or you can stand a folder or book on its end between the partners to hide the sheets.
