Mary- Once you know more about your child's reading challenges, talk to the Schenk School (Atlanta's premier school for dyslexia) and the Atlanta Speech School (deals with learning challenges, especially reading based ones). While private school may not be something you are interested in doing, both schools have outstanding programs and can be a great resource. Even if you leave your child in her school, I would think it would be helpful to see what the "best of the best" are doing for kids with reading challenges. My kids have friends at these schools, and the parents rave about how helpful the administrators and staff are.
BTW, I hate that my kids' have so much homework. I heard on the radio this week that there's a new study out of Duke Univ. that shows homework is a waste of time. I'll have to search for it.
