There is not all that many "technical" rules in touch footy, its pretty straight forward. And being kids touch footy, the ref will step in and explain anything to them if need be
I dare say your job for a kids team would more involve rotating the players so they all get a fair amount of time on the field.
7 On each team
6 plays for each team before the ball is handed over.
Must play the ball where you were touched. - can not advance the mark.
A turnover occurs when - the ball is - dropped - passed forward - the dummy half is caught with the ball.
A penalty occurs when - the defensive team is offside - not back 10 meters from the play the ball.
The ball can not be kicked.
Just to expand on what Tagman posted a bit further....
After a player is touched, they must play the ball............which simply involves placing the ball on the ground and stepping over it. It is not played with the foot like in rugby league.
An offensive player can also perform a touch. This is often used when trying to promote the ball quickly to the other end of the field. The player with the ball simply just has to touch a defender and then play the ball. The dummy half can quickly pick up the ball and pass to another player while the defending side is still retreating their 10m
Dummy half cant be touched with the ball or score a try. Always have to have at least one pass before being touched or scoring a try.
A try (or touchdown) is worth 1 point.
A turnover of possession is also required if a player runs over the sideline while in possession of the ball.
Hope that helps.......good luck with it
It can be a very fast game, but a hell of a lot of fun.
