Cones are used to mark a square and a smaller triangle in it.
Distances must be adequate to the given age-groups and their technical skills.
Two players are placed into the triangle without a ball and two players are located on each lines of the square as shown with balls.
Defenders are changed periodically.

Attackers with ball outside have to dribble through one of the line of the triangle and leave it through an other. The attacker gets a point when he can dribble through and goes to an other line of the square without a touch of the defender. After reaching the other line attacker passes the ball to the next-coming team mate and replaces him. The defenders have to try to touch all of the attackers when they come into the triangle. When the defender touches an attacker he passes the ball out to a next-coming attacker. 
The defenders can act in the triangle only.
