We have a copy of Roll of Thunder, Hear My Cry somewhere in the house. It was my mother's, actually--she used to do freelance work when I was a kid, and she spent some time writing educational guides about various books to be used in schools. Roll of Thunder, Hear My Cry was one of them. She never really showed the guides to me, though, so I don't have a good idea of what she actually put in them. It sounds interesting, though, so I might have to see if I can find it now.
