Set up a square that is 10 - 15 yards wide. Depending on the age and the numbers you have, use 12 or 16 players. Players line up on the edge of the square as shown in the diagram, and each player starts with a ball. On the whistle, all of the players dribble the ball to the opposite side of the square. When they get across the line, they perform some sort of dribbling/turning move to change direction (you can instruct them to do a particular move or leave it up to them), and then dribble back to their original position.
1. Keep the ball under close control.
2. Pick your head up in between touches.
3. Accelerate after the turning move.
