Nope. I just learned it. I remember telling my son's teacher that I didn't get it and wasn't even remotely going to try and learn it.

Learned it in Iowa, and it makes math sad.
We homeschool in Colorado so we ditched it.

This may or may not apply to Base 10 Blocks, but this article explains a lot of the issues people have with the CC math.
http://www.vox.com/2014/4/20/5625086...ated-heres-why I'm not going to paste it all in because there are a bunch of embedded images and infographs that are necessary to really understand it. Here's the gist, though: Quote:

Are other countries practicing this method?

Yes. Other countries who kick our asses in mathematics. One popular math curriculum is actually called "Singapore Math."
The entire article really is worth a read.

Bottom line is we SUCK at math. No, seriously, Americans across the board are getting thier asses absolutely handed to them in the math and sciences by, especially, certain Asian countries (India and Japan, to name two). Have been for many, many years. We import a huge number of foreigners to help support our scientific efforts here in the US, or export the work to those countries.
We need to get better, and there are a number of different ways we're doing that. To us old folks, some of it makes no sense (I'm in that category), but they're trying to teach it in different ways so kids can do better at it, especially in the long run.

Interesting sidenote -- we suck at math, but we're much, much more entrepreneurial than most of those same countries that kick our ass at math. They are working on trying to encourage more of an entrepreneurial spirit among their students. It's a "technical proficiency" versus "creating thinking" thing, apparently. We're better at creativity, and they're better at technical stuff.
But that means they usually end up working for us. What we want to do is improve our technical proficiency without killing the entrepreneurial capability.

I'm all for us getting better at math but some of this seems like it's trying to be complicated for the sake of poetry.
Johnny uses a timeline to demonstrate visually that subtraction is a distance between 2 numbers. Fine. You teach the concept. The timeline is a visual representation of a concept. But to then teach that that is the way that they should always determine the distance between 2 numbers is just silly. I don't think we do any of us any good dumbing stuff down even further.

That article does a really nice job of showing how we actually, in the real world, do a lot of these tricks anyway. We break complex math problems down into a series of simpler math problems (think of how we figure 15% tips in our heads).
