Clear the craft or game refuse and pass out the snacks and drinks. Make sure the teacher gets a snack, and have a bite yourself. Watch the kids and head off any food fights or major accidents. Recruit the rambunctious to take the trash can around to the group. If a child wants to save her food, that's OK, she can usually leave it on the desk.
As kids finish eating, direct them to stay at their desks or tables quietly until you begin the final party game.
