I'm curious - I'm not exactly sure what you mean by the "nowhere near Western education" comment. What exactly do you mean by that?
We homeschool our kids, and we actually use the Singapore Math program (slightly rewritten for US students) for our math instruction. I like it a lot - I like the way it approaches the concepts, and find it is a very good system to work with, assuming you're enthusiastic about teaching it (which I pretty much am).
I'm not doubting you or anything Mike, but I'm kinda skeptical about the Singapore Math program thingy you mentioned. Is there any official authentication sorta thing that whatever material it is you're using to teach your kids is genuinely from Singapore?
If you like it, I really don't think it's what we're getting here. There's no way ANYONE who truly loves and enjoys math would like it. Concepts? Math here isn't about concepts. The average student here wouldn't understand a thing about simple/basic math concepts, I can assure you that. The only thing we're taught/forced to do in school here is tedious calculations to trap us into making careless mistakes and/or "standard questions" - questions that follow a specific template and are always solved using the same method/routine. That's right, we don't have math "problems", we only get math "questions" here.
I'll put it this way: There's only one place in the world where kids can shamelessly say, "Math is easy! It's just all about practice!" And that place happens to be Singapore. (Oh, and those kids are right by the way.) Math in this part of the world is stupid; it's all about drilling, not about thinking. ZERO thinking.
Okay, so that was me dissing the Singapore Math program that claims to be the best in the world.
