Have some of the parents or 1/2 of the kids spread out in circle on the field.  The kids dribble around and can pass to any parent or kid on the perimeter.  The parent or kid passes the ball immediately back.  The kid then dribbles and passes their ball to another person on the perimeter.  Trying to pass to every person on the perimeter.  Then score a goal and/or switch the other half of the kids to allow them to do it.
