Costume party: My 7 year old boy wanted his class over for a costume party. So after wondering what I would do with 20 7 old kids for 3 hours, I decided to start with a scavenger search for one hour (outside), then some light food (popcorn, carrots...) then for 1 hour it was "theatre". I divided them in teams of 5 or so. Had each team invent a story that made use of their costume. I then had each team act it in front of the other teams. I finished with a paper airplane flying contest. It was great fun.
