My quadrant supervisor just suggested a book titled "A Framework for
Understanding Poverty" by Ruby Payne.
I'm running to the local library (or to Amazon) to buy it. From what I
understand there are school districts that have an entire curricula
based on Payne philosophies (and from what I've heard, they're pretty
positive and significant).
Best of luck!
PS. If you do a google search on "Ruby Payne" you can find oodles of
sites that will give you an overview of who she is and what her book is
