Broken Telephone: Every row in the classroom forms a group, a metaphorical 'telephone cord'. The goal is for each group to race in order to verbally pass a word, phrase or sentence down their team's telephone cord and the last person must repeat it to one of the teachers. This game is sometimes called でんごんゲーム in Japanese.
