This is an all-class mixer speaking activity. It includes 18 unique sets of twins. Each student sheet has 5 statements. Students mingle, trying to find their twin (the other person who has all 5 of the same statements, though in a different order). Each sentence uses a form of a spelling-change verb following the pattern of acheter or préférer. "J'achète une trousse violette." This is a low-stress activity focusing on speaking and listening. Students need to write the name of their twin and then find something that they have in common (related to the vocabulary and grammar of this activity). Vocabulary corresponds to Bien Dit 1 chapter 4. Easy to edit to match the vocabulary from your book.
