I'm working at a summer camp at my school and we played a pretty fun camp last night, that the kids seemed to enjoy for the most part. It was called Mission Impossible and they had to go in their classes around to 10 different stations, seeing if they could complete various challenges in 5 minutes.
Some of the stations:
1. Trying to make one of the teachers laugh.
2. Having to guess 10 words in 5 minutes, based on the teacher explaining them. Example. Teacher: "It's an animal that eats bananas" Student: Monkey!
3. Making shapes as a class. Square, diamond, etc. They did 2 in 5 minutes.
4. Listening to a song and writing down words they hear. If they get a certain number, as a class they get their challenge completed token.
