Not neccessarily adding the fun aspect but a couple of things to look out for with this age group. Throwing: Make sure the kids are stepping toward the direction of the throw with their opposite foot. If you throw right handed - step with your left. I know this seems obvious but you'll notice it is not intuitive for all kids. Once they start doing it - their throwing improves. Catching: We all know kids can't sit/stand still and when catching a ball they love to throw in all kind of body movements. They hop, lunge toward the ball, turn sideways, etc. Teach them they only need to move one thing to catch the ball (and protect themselves) --- their glove! Use the soft baseball -- this age still misses a lot! Batting: Good stance with proper hand position. Hands together - right over left (righties). Hit off a tee. Final hit off the tee -- let them run around the bases. Kids love running the bases! Just my thoughts on some basic stuff --- they are still real young!!! Good luck!
