You could try making a short "jeopardy" type game, or a jigsaw type activity in which you hand out pieces of the text, or written questions and answers and they move around the room to match up. At the end of your lesson or activity, give them a short quiz to assess if they learned what you were trying to teach. Remember to start your lesson with an agenda: write the goals for the lesson on the board or OHP (An overhead projector).
