Two players demonstrate various tasks with 2 and 3 balls from the simple ones to the more complicated.
For this skills development the main elements are ball familiarity, balance, cooperation, communication and concentration. 

The kids make different movements with ball, for example:

1. Both balls are at the players' feet. Push the ball with the sole of the foot to each other, then roll it across the body with the sole and change the ball again. They are making this task with the same leg continuously, then change periodically. The balance, the gentle contacts and cooperation are very important.
2. Both balls are at the players' feet. Pass the ball with the inside of the foot to each other, then roll it across the body with the sole and change the ball again. They are making this task with the same leg continuously, then change periodically. The balance, the gentle contacts and cooperation are very important.
3. Both balls are at the players' feet. Push the ball with the sole of the foot to each other, then roll it inside across the body with the sole of the opposite foot and change the ball again.They are changing legs continuously during the implementation (for example,they push the ball with left and roll with right). They change direction after some repetition. The balance, the gentle contacts, cooperation and fast footwork are very important.
4. One ball is in the hands, the other one is at the opposite player's feet. Both players are moving continuously. The ball on the ground is going between two legs, when the opposite player throws the ball in the air, the other pushes the ball with the sole of the foot. The balance, the gentle contacts, and cooperation are very important.
5. There are 3 balls. 1-1 are at the players' feet, and the third is in hands. The balls on the ground are going between two legs continuosly, the third one is thrown to each other in the air. The gentle contacts, balance, concentration and cooperation are very important.
6. One ball is in the hands, the other one is at the opposite player's feet. Both players are moving continuously. The ball on the ground is going between two legs, when the opposite player makes a bounced pass with hands, the other plays the ball with the inside of the foot. The balance, the gentle contacts, and cooperation are very important.
