This is a communicative game for reviewing past tense.Divide the class into teams. Brainstorm past tense verbs (get a lot). Explain the rules on the right. Model the exercise. The idea is that the first team starts with the word "First", the second team "Next", the third team "Then" , the first "After that" and and the second "Finally", making past tense sentences. Every time you come round to "First" the story can start in a new situation.
