Everybody sits in a circle, except for one person who stands in the centre, with a piece of paper. The person in the middle than says someone's name and throws the paper into the air. The person who's name was shouted then has to run into the middle and catch the paper before it hits the floor. If they don't manage to catch the paper, then they rip a bit off the paper before continuing. (If you do catch the paper, continue without ripping anything off).
Piece of paper
Great for learning people's names, and as a simple ice breaker!
