Cut out pictures of products, or complete advertisements with the slogans omitted, from newspapers and magazines. Write a different number on each one. Then write a list of possible (or actual) slogans for the products. For low level classes, these might be quite straightforward, but for higher levels it’s fun to include some puns and ambiguities. Divide the class into groups of three or four and give them a copy of the list. They have five minutes to discuss the slogans and to write down what products they think are being advertised. Hand out equal numbers of pictures to each group. Students have one minute per picture to decide which slogan refers to which picture and to write the relevant reference number against the list (timings can be a bit flexible). The pictures are then all handed on to the next group ... until everyone has seen all the pictures. While I’m checking the answers, each group writes a new slogan for one of the products they end up with. I usually offer a prize for the most correct answers, and for the slogans – sweets are usually popular, especially if everyone gets one!
