It's very useful to improve speaking skills. You divide the class in groups by 4 pupils. Each player need a pawn, throw the dice and count, when he/she stops on an answer-stone he/she formulates a question. The team decides if the question can be right or wrong. (when players arrive on stone 39 and the dice makes 2 or more, they came back to 40). Time 20-30 minutes. I hope you like it for your pupils!
