I would just have them do layups, show them how to dribble and shoot.Shw them how to shoot free throws.Show them that the right way to dribble is to use the finger tips.The same with the shooting.Point out to them that when they shoot the ball it is like waving at the basket.Show them the proper defensive stance which is a crouched position.Tell them to keep their eyes on the ball and the man with the ball.Tell and show them to play defense with their feet at all times.This is some of what we did in our first practice.
