Manipulate the throws to keep things fairly close. This is easier with a count-down timer on your watch. Use the penalty area as a boundary. GK in goal. Teammates line the 18 yrd box with balls.
Coach puts ball in play.
It's always 2 attackers vs 4 defenders. The ball and players may travel within the goal box, but shots must be taken outside of it. If a ball leaves playing area, nearest player on touch tosses another up, then shags. When one team scores, the other 2 swap out. LOTS of action, emphasis on shooting at the 1st chance, partner moving open in front of the goal.
