In regards to how its covered M you are spot on
I know there are bodies here in the UK trying to get together to form a collective voice for Pagan parents, but to be honest I can't see a great deal being done openly. I know the Pagan feds approach is to simply advice and to go through the channels you threw forward, ie school board etc.
Maybe that's what is needed, a general overview of the diversity of Paganism that can represented by a body of diverse Pagan's. I may get shot for this but Heathenism is completely different again and does deserve its own treatment. If you mingle the two it starts getting confusing for adults never alone children lol.
But the advice so far is good, please keep it coming
Now I had better put my views forward here lol, I actually voted yes myself. The reason being that if its taught in schools you get them when they are young enough to not have prefixed ideals that can cloud open minded discussion. You'd have a generation of young adults that would be able to understand a more broad spectrum of religion in our society. In my eyes that can't be a bad thing, it can only bring good, after all the biggest stumbling block to a lot of Pagan's is getting past the preconceptions that have been created by the media in general.
How should it be represented though?
That's a tough question even for me, I'm what you may call a very sexual Pagan and that hasn't got a great deal of room in our younger classrooms. Lets be honest one wiff of the nature of something like the great rite and you'd have hundreds of parents hitting the roof!!!
My approach would be to focus on such things as seasonal festivals in a very child like manner. Lets be honest most of our kids celebrate good old Halloween in a manner that is not far off our own Pagan festival

Then we bring it forward to the teens, they are starting sex education and I personally believe pointing out the sacred aspects of duality would only help make our youth far more responsible in certain choices.
People to contact, I echo M once more here, work up the chain of authority but also be aware of religion in our law. There are a great many rights that allow us be a little more free with our beliefs. This also has connections to who do we contact in regards to tolerance, the more informed we are the better
