I just updated my curriculum page, and listed my favorite curriculum from over the years (scroll to end of page). To my surprise, most of them ended with .com or .org. I have a thing for online curriculum.
The downside to that is that we end up buying new computers... often. My daughter seems to be able to trash a laptop in 18 months. My son's last longer, but his choices are more expensive.
Fortunately, I fill in the blanks with free home education resources such as those found on my FREE HOME EDUCATION WEBSITE
