The home schooling world has grown by leaps and bounds since I was in grade school. Here, I'll post some links to web sites that I've found helpful. Here are a few to start off:
The Joyful Noise Schoolhouse My friend D blogs here about the joys of raising her "great big family of little peoples." Read about her tips, comedies, and recipes. Great fun!
Rainbow Resource This site has TONS of books. You can start here to see a wide variety of curriculum.
Amazon I check for curriculum here since I often find it used or on discount.
