I just googled and found this (these are most commonly used as a treatment strategy for kids with autism so you will see it mostly in that area, but really most kids benefit). I just found this and will be downloading it and looking it over at work tomorrow, but it looks like a great free resource: http://www.autismspeaks.org/science/...isual-supports

This is a book I have had access to at work and recommend to parents: http://www.amazon.com/Visual-Strateg...ef=pd_sim_b_22
