If you're a new camp counselor, or if you're looking for some activities to do with your campers, here are some fun team-building activities for adults: 1. Icebreakers: Icebreakers are one of the best ways to get people talking and laughing together. They're especially useful for getting to know each other better at the beginning of a session or program. 2. Charades: Charades is one of the easiest team-building games around. You can use any subject matter (sports, movies, animals, etc.).
