Wow, thanks for that file!
I have been playing it in class by just writing the role on a 3x5 notecard. Having the pictures and rules on the cards is much nicer.
One other thing I do in class when playing with a seer (I call them a detective) is I don't give them a silent thumbs up/down. I actually say out loud, "That person is/isn't a wolf." If the detective is dead, I still call out to them in the night and still randomly declare wolf/not wolf (even though the detective doesn't open their eyes and choose some one). This is just to keep the wolves guessing.
The Little Girl role is one I had never heard of. It sounds like a really neat idea. Anything to reduce the number of villagers since the kids hate just being a "plain old stupid villager."
Ora, lege, lege, lege, relege, labora et invenies.
