I use battleships for a variety of activities:
1. As a whole class activity to encourage speaking skills. To do this I project the grid on to the board in Smart Notebook. I choose five squares secretly and pupils have to try to guess which they are using target language only. When a square is guessed correctly I write the name of the person who guessed it in the square. When a square is guessed incorrectly I put a cross in that square. The five winners usually get a small reward.
2. For pair work to encourage speaking skills. I print copies of the grid, usually two to a page to save printing costs. Pupils play in pairs, each choosing five squares and taking it in turns to guess the others squares. The winner is the one who guesses all 5 chosen squares.
3. I use the small printed grids for listening practice exercises. On my own sheet I number squares 1-10. I then read out the sentences which lead to each of those squares and pupils have to write the numbers 1-10 in the correct boxes. I then display the answers on the grid on the board. Pupils can mark each other’s or their own.
