it's a little more info then would fit on a "Cheat sheet". Check out www.arrl.org and look up operations. The "ARRL Operating Manual" that a ham uses is probably a bit more rigid and structured and even more elaborate than needed for FRS but the feeling and intent definately translates and many of the operations guidelines will apply directly. The Ham operators in your area probably are involved in JOTA - Jamboree on the air with the scouts already and you could certainly find a local ham to come in and give a 1/2 hour introduction into proper operations techniques with a small 1 page handout of guidelines applicable for the audience and intended usage.
