They don't produce their own math curriculum; instead they offer 3 different options from different companies.
Singapore Math was good for our 3 of our sons who didn't need a lot of repetition. Our daughter struggled with it, so we switched to Saxon Math, which was for kids who needed more repetition. It was definitely more repetition and she learned the material, but it was more than she needed and she didn't like it because she felt like she was doing stuff she knew over and over again.
We finally settled on Math U See (not offered by Sonlight) because it just seemed like the right balance for her. One of our sons switched with her because, while he did well with the other curriculum, he just liked his sister’s book better than his own. (He’s two grades behind her, but he's doing the same math.)
Pros of homeschooling:
1. Not tied to the school calendar. (Our spring break is never when theirs is - we go when there are rooms available.)
2. We don't worry about grades. At all. We worry about learning, and if they spend the time and put forth the effort, they will learn.
3. People like to talk about the social skills they miss out on by homeschooling. I’ve seen the social skills of public school kids - I'll pass.
4. We like spending time with our kids.
5. No leftist agenda from the teachers. (At least, none that I can tell. I have to keep a close eye on her, though. ;-)
Cons:
1. It takes time and effort. (Bedtime story isn't 5 minutes and a good night kiss anymore - we read about 30 minutes a night. That's my job in the deal - my wife does the rest, although I do help with the planning and organizing, such as it is.) (Sometimes our organizing isn't so organized.)
2. Different states have different rules - see www.hslda.org. (We haven't had to deal with any of that because the rules are very homeschooling-friendly for overseas military families.)
3. You have to pay for materials.
5. No leftist agenda from the teachers. (At least, none that I can tell. I have to keep a close eye on her, though. ;-)
LOL!
