Put students in pairs and give each a copy of the worksheet. They need to keep their sheets hidden from each other so the other partner can't see what they have written in their sheet. First, they choose where to draw their own 'battleships' (based on the original 'Battleships' game). Do this by drawing a line around boxes in a line going horizontally or vertically. Usually 5 battleships with 3 of 4 boxes in length and 2 of 3 boxes in length is a good amount, although you can tailor this to how much time you have. The aim of the game is to guess where your opponent's battleships are. This is done by asking them the question on the left column and then using a word in the box to complete the question. Each answer must be a FULL answer, e.g. 'do you have a pencil?' - 'Yes I do/No I don't'. I.e. 'Yes/No' is not acceptable. The idea of the game is to practice asking questions and answering in the correct format. You must answer in the affirmative (e.g. 'Yes I have') if your battleship is on that box, and no, if not. The ss must keep asking questions until they have located all their opponents battleships. Once they hit upon a box that their opponent answers yes to, they can 'tick' it in another colour, or indicate however they want. I find ticking and crossing boxes a good method.
