The first player plays a pass to his team-mate, makes a run and shoots on goal.
 

A simple 'give and go'. Basic stuff but very important. If your kids can do this quickly and accurately they will win more games than they lose - promise!

Coaching points

1.Make sure all passes are accurate. Don't play the ball first time if the ball is not an accurate one.

2.Timing the run so that the player arrives just as the ball does. But don't stand around waiting for it.

3.Correct shooting technique, i.e.,
    Head over the ball, hit with laces and aim for the far post.

As a progression get the player knocking the ball off to follow the shot in.
