How and what drills for players to gain balance?

How and what drills can i use for my u12 so that they can balance their body while shooting or landing?

when i was younger and played at a high level we was always made to stand on a bench and get a ball passed to us of which we had to balance on the bench , the balls would come harder and quicker thus improving balance. in terms of shooting it comes with technique , it is vital that the shooters have great stability lower down of which will lower ther centre of gravity , therefore make sure that their legs are shoulder width apart when shooting. hope this helps

I use a balance board (the phisio's use this) to teach balance. You let the player first balance on both feet on the board - pass a few balls to her & vary the passes. Then you let her stand one leg repeat the above etc. Hope you understand.
