My oldest is 10. We are just finishing up our first 4 year rotation. We have done it in a co-op setting from the very beginning. I have loved it and so have my kids. By doing it in a co-op we do more of it than I would on my own at home. We get to do a lot of the hands on activities and I have gotten to learn from other moms about how to use vocabulary and teach writing. (I have an engineering background). So, obviously, I would say definitely yes. Although, if I wasn't already using it and in a co-op with it, I have to say I would consider Sonlight or My Father's World.
