Four players will kick a ball and start running around the bases. The outfielders have to put the balls in the color coordinated buckets before the last runner gets back to home base. 

I don't have color coordinated buckets, I would need to use a polyspot or some other way to show what color ball would go where.

I also have a larger class, so I could see this working with 5 or 6 balls if needed. Would need to figure out where to put the buckets.
