Split-passing - Good for all ages, as you can increase the difficulty or expectations of players as skill/age level gets higher.

Form 30-yard circle of 10-12 players. Have 3 players inside with a ball each. Each player with a ball inside is seeking to get outside by passing to any player forming the circle (when you pass out, you take that person's place -- player receiving carries inside with the ball). CHALLENGE: You can only pass out by 'splitting' the other two balls. So you must dribble inside until you see a player outside to pass to, and the path of your pass will go between the other two balls (being dribbled or passed by the other two players inside).

Works DRIBBLING, PASSING (especially penetrating passing), COMMUNICATION, most importantly VISION.
Great introduction to skills for younger ages. For older/higher skilled - good active warmup: use only left or right foot; serve all balls in the air; any passes which hit another ball or player, or travel outside the circle cost shuttle runs after drill, add 4th ball. NEVER ALLOW THE BALL TO 'DIE' - players inside must continue to carry the ball - they can not stand and wait inside.
