We play a lot of silly games around here. One of our favorites is called Ships and Sailors. Basically there are commands that are called out and the kids get in their groups to do them - such as "three men rowing" and "five men pointing North." It gets the kids to meet other campers and mix and match up their groups. There are silly commands like "barnacle", which is where you run to the wall and cling yourself to it, and "beached whale," where you get on the ground and flail your arms. "Captain's Coming" is a lot like Simon Says (you can't do anything else until the command "at ease" is said).
It is quite silly and fun and we love it - here are some shots from yesterday's game:
