Hand out a worksheet to every child or to each pair of students, if you prefer. In pairs, children have to choose a set of pictures but they mustn't tell their partner. The partner has to ask questions 'Do you like eggs?' 'Do you like strawberries?' 'Do you like milk?', and the other pupil has to answer 'Yes, I do' or 'No, I don't' according to the set he/she has chosen. When the pupil that makes question knows the set, he/she asks 'Is it number 1?' You could also play Bingo with these cards. I hope your pupils have fun!
