After going over the quizzes, students worked in pairs to make an answer key for a review assignment that they had.  They have done this for each chapter.  We heard lots of good statistical vocabulary and discussion.  The groups turned in their answer key to be checked for correctness at the end of the hour.  With any additional time, students could work on flashcards for the vocab words.  Consider trying a review game, like Catchphrase or Taboo with the vocab, like we did earlier this chapter.
