do you mean games that will teach them where a WD is allowed to go and such?

I use to coach the 4-6 yr olds and use to play a game that they had to put on any bib and then run around the edges that that bib was allowed to go.  I also did one that they all put on bibs and had to find their opposition position...ie if you had the GD bib on you would have to run to the GA.  you can also download some blank courts and have them take them home and colour in the areas that each position is allowed.  kids love homework....(at that age...lol)  just remember to mark where the goal ring is for your team or you will get them back with the GA and GD at the same end.

hope that helps.
