Instrucional league 1st-3rd grade

What is the most important skill to to teach these youngster the way it works is we have an hour we do skill training for 1/2 hr and then they play a game the last 1/2 hr. (there are 2 teams ) I play dribble tag, red light green light, basic passing and shown them proper form but hard to do because we play on 10 foot rim so I have them use the wall. then we move to the basket, I don't do much about defense they seem bored with it. Just showed them proper stance stay between ball and basket. Ok after all that ramble the most important part is to have fun. But if anyone has any good games that you can incorperate with passing drills I'll take it. Thanks I hope you can make sense of my ramble many thoughts as i was typeing.

Lots of dribbling, passing, footwork, and games. That's about all you can do at that age. For footwork you do jump stops and real simple pivoting. Bob Bigelow has some good stuff on that.
