Signs competition

On the board, draw or stick pictures of signs, eg road signs, sign from around the school, no smoking / mobile phones signs. (You can also get pictures online and show them using a projector or an IWB). Write a number next to each. Divide the students into three or four teams. One by one, each team chooses a number and makes a sentence to explain the rule. They get a point for a correct sentence. Remove or erase signs that have been correctly defined until all signs have been used.
