Ghost, Ghost, Boo
Ghost, Ghost, Boo is an adaptation of the classic Duck, Duck, Goose game. All children but one sit in a circle with about a one-foot space between each child, and the remaining child is chosen as "It," "Grave Keeper," or whatever fun name occurs to you. The Keeper walks around the circle, lightly touching each child's head and saying either "Ghost" or "Boo."
When the Keeper says "Ghost," everyone remains seated and the Keeper continues around the circle. When Keeper says "Boo," the tapped child stands and tries to tag the Keeper before he makes it all the way around the circle to sit in the "Boo" child's vacant space. If the Keeper makes it back to the seat without being tagged, the tapped child then becomes the Keeper. If the tapped child tags the Keeper, he sits back down and the Keeper continues the game.
The Keeper cannot "Boo" the same child twice in a row. When Keeper, some children will never get around to actually "Booing" anyone. Make a rule that they may only go around the circle three times and must stay near the circle. If rambunctious running is out of the question, have the chase portion of the game be done on tiptoes, hopping, or some other slower movement.
