party planning

Hmmm....how to entertain a bunch of first graders that doesn't involve trashing my house? Yes, it's party planning time and I'm looking for ideas that can be done outside that have an autumn theme. decorating mini-pumpkins? bobbing for apples? My goal is to not attract bees in the process. This is why I am not a preschool teacher. I am definitely a mom that has to outsource the arts and crafts portion of childhood. useful comments are oh so welcome here.
