Some friends of ours at church who home school their four kids gave us a Sonlight catalog about two months ago. After looking through it we realized that it is very similar to what we are already teaching the girls. Really, the main difference (besides price) would be that it's all pulled together and planned out for me.
Currently I gather all the books and materials myself. Then on Sunday evenings I spread everything out and plan out a week's worth of school work at a time. It takes me a couple of hours to go through it all, write it out, and hand make any materials for projects and crafts and photo copy things like maps. Then after our school work is done for the day I go through my book and make note of what we actually did. On weeks when I don't have that much time to devote to planning and record keeping we do less fun stuff and I go back and make notes about what we did at the end of the week.
So, we are thinking that when Daniel gets his bonus in February/March we'll order the third grade Sonlight curriculum and try it out. We'll use it for both girls and just add the advanced reading books for Danya. Third grade is the year that Sonlight starts having all the reading tie in with their history reading. I do love the fact that their program is based on a lot of reading with the kids. That's our favorite thing to do!
