I think Dodgeball is great...but I do have a memory of some groups of girls standing together, kind of scared, as boys with big arms zipped balls at them. Probably 5-6th grade type of thing. Probably not a ton of fun for them, to be honest.
Of course, the way around that is to offer an alternative for the kids who really don't want to play, not to ban all kids from playing dodgeball.
