Students stand in a circle. Clip a picture to the back of each student they should not see their own picture. They must not tell each other what picture is on their backs. They must circulate and ask each other questions which can only be answered by yes or no until they figure out what they are. After they have figured it out, they keep circulating to help others find out what they are. You can make it more challenging by giving each student a class list and getting them to check off each student that they ask. They can only ask a student one question. If you have advanced learners, after the activity, you can discuss the appropriateness of the person s object to their own personality.
