I print these slides asking review questions about Southwest Asia (the Middle East) and hang them (mixed up) around the room. Each student starts at one of the slides and reads the question. (On the left hand side of the card.) They then search around the room until they find the card with the correct answer on the right hand side. Students write down the picture at the top of the card on a piece of paper. No matter what card they start at, if they are getting the correct answers, they will start and end at the same card. If they write down the pictures, they can easily at the end check if they have the correct order.
