Feed the Reindeer Relay - the kids on the scooters collect the reindeer food (if you haven't got these then the children could use the crab walk instead) and give it to the throwers (who are standing in a hula hoop). The throwers toss the food into the bucket. So groups of three kids for this game.
Circle dodge ball-I like the listed alternative better, that the tagged person switches places with the person in the middle.. I think I would start with 4 kids in the middle.. Make circle with markers in center of gym.
