Games to play with groups of kids outside?

I'm with a camp, and I'm teaching "outside games" with groups of kids (Pre-K, Kindergarten, 1st/2nd, and 3rd/4th). What are some good ones? Anything from duck-duck-goose type games, capture the flag, types of tag. Preferable simple and easy to teach.Games to play with groups of kids outside?

when its hot outside instead of duck-duck-goose, play dry-dry-wet. instead of saying goose they dump a cup of water on the persons head.
