Place 10 balls on the front line of the goal area box, evenly spread apart. Time as each player kicks each ball in succession, until all 10 have been shot. Add 1 second for any shots that missed the goal. Use this at the end of each practice and keep track of each player's times. Stress to your players that progress (getting faster and more accurate) and consistency is most important. As the season goes on each player should be able to see that he/she is getting faster and more accurate. My players beg to play this game at the end of each practice. 12 U10 players should take near 15 minutes to do (if you have players that already took their turn help with setting up the next player). This exercise should help each player execute kicks and shots quickly, with increasing accuracy.
