This game may better later in the year when players know one another pretty well.
In this game, students write down three interesting facts about themselves (characteristics, accomplishments, cool events, etc) on a notecard, and the group tries to identify whom the facts describe.
Explain the nature of the game and remind everyone that they are not to explicitly identify themselves on the cards. Then give everyone a note card, and have everyone write down three interesting facts about themselves. Then randomly choose card by card and have the group guess whose card it is based on the facts.
Variation: Instead of having people write their own cards, assign a person to each person to describe in 3 positive facts. Then have the group guess whom the facts describe. Reveal who wrote the facts as well.
