That's so funny. I own a teacher's guide for Roll of Thunder, Hear My Cry. I wonder if it's your mother's? Who did she write for? This, I am pretty sure, is for the Teacher's Curriculum Institute, which is a quite excellent source of curriculum material, located in Palo Alto, CA. They've moved on from teaching guides like those, though, to actually publishing textbooks, having seen the way the wind was blowing -- e.g. boxed curricula, not teacher-cobbles-together-interesting-units. I liked doing the latter, but it is Very Frowned Upon, these days.
