I use this worksheet as a follow-up for teaching the past continuous. The first day I present the grammar point and practice along with the book exercises, and we play the board game "Clue." The following day we watch this movie as a class with the worksheet. I wrap up the class by role-playing "Murder Mystery," a game you can find on various ESL sites. It's a great way to learn, practice and use the past continuous with a theme for the whole lesson.
