This activity provides practice plotting and naming points on a coordinate grid. Hand out three Battleship game boards to each student. Using a transparency of the game board, explain to the class how the game is played. Unlike the board game, the ships can be placed diagonally.
Students work in pairs until one person sinks all of the other person's ships or time runs out.
If time runs out, the person with the most hits wins. Pair students and give them time in class to play a game. For homework that night, have them play a game with someone at home. This is the reason that each student gets three game boards - one to use in class, and two for homework.
