Set up in the 23m zone and create a couple of zones with markers and give those zone different points. If they play through the zone and score it is worth that many points.

Coaching points are trying to have players identify where they need to go to earn more points if they score. E.G. if you go through the wide zone and score it's worth 3. This could be because you coach a team that attacks to narrow. If the defending team then hold to wide you have a free entry in the middle (should you take it?) when it's only worth 1pt. Makes you think!

Change the system of where points are scored. Change the numbers within the game.
