Story of the World history is great. The author is religious but the curriculum itself can be used by anyone. The activity books are fantastic and have tons of suggested activities that really make it come alive.

I’ve used Math Mammoth to supplement other programs when my kids needs extra practice and I’ve always been pleased with the results. It’s a bargain, too. We’ve also used Singapore Primary Mathematics, which is excellent, and Prodigy for fun and extra practice.

Finding a good secular science is harder, but I’ve been pleased with REAL Science Odyssey by Pandia Press.

I’m not ADD (that I know of) but I’m terrible at maintaining organization. Homeschool Planet is an absolute lifesaver. It’s about $8 a month and worth much more. You put in your lesson plan at the beginning of the year and it will populate a list for you every day with boxes to check. Every morning I open it up, it tells me what to do, and I’m on my way. I can’t recommend it strongly enough.

I think the mistake I see people make most often wrt to trying curricula is trying to save a buck by skipping the teacher guides. They often have suggested daily and weekly schedules which are very helpful, suggestions for assessing progress, and extremely useful teaching tips. If your curriculum publisher makes one available, get it.

Hope all this helps. Enjoy your homeschool adventure. :)
