In our club for our U7 boys division (comprised of 6 &7 yr olds) we play 7v7 (6 field +1 goalie). I would like them to play a 3-3 formation. flat 3 defenders flat 3 forwards just to keep it simple. I am having the hardest time teaching these kids to stay spread out, not bunch up around the ball, and pass the ball to each other. To try and keep their positions and just move up and down the field while still keeping their basic 1 line 3 person shape. Does anyone have any practices or drills that help kids understand how to move together as a line and team? How to keep their shape without crashing in around the ball and pass the ball to one another? Or is that just something you have to keep repeating and playing over and over until eventually, when they turn 9, they'll get it?
