Divide the group into two teams and have them stand in single file lines. Whisper a somewhat complex sentence (according to their level) into the ear of the first person in each line. Make sure no one else hears. Give the same sentence to each line. Then each person must whisper it into the ear of the next person until the end of the line. The last person must either say the sentence or write it on a whiteboard. The team whose final sentence most resembles the original one wins. In case of a tie, the fastest team wins. Try giving an easy sentence to start with to build confidence before moving onto a difficult one. If the game is too hard in the first round, learners will decide it's no fun.
