Re: Can someone tell me....

[leisuretime]

I suppose it explains it, but it certainly doesn't make math easier. If anything, for me, it's the juggling of numbers that makes math hard, and this subtraction of 12 from 32 now has kids dealing with four different equations, remembering all the variables from them, and then adding all of them up.

I just don't like it.

I struggled with math, the way that article explains it is how I learnt myself math, if they taught me it that way I would have understood the rest a bit better.

Oh...boy

I was really good at arithmetic as a kid, and I could solve problems multiple ways to check myself.

Different people learn differently, and find different ways easier. The problem is when someone starts saying, "This is the way we think." No, it might be the way you as an individual think, but different kids learn the same math different ways. Good math tutoring has to understand that.

So the Common Core method, instead of being better for all kids, will be better for some, and worse for some.

Now, that said, taking that specific problem, and splitting 20 into 10, 5, 3, & 2, looks kind of silly to me. When I was a kid, my brain ran fast enough to do that easily. I can understand why some people feel more "sure" doing it that way. But as a practical matter, it feels really awkward. Why create more possible error points? You have base10, exploit it.

It might be a good exercise while learning the math. No, I should say it would be a good exercise as part of instruction.

It's not a normal way to solve the problem.

And I actually read to the end of the article, and it seems like the Common Core guidelines are actually trying to get it right. Teach multiple pragmatic ways of dealing with numbers. OK. That's hopeful.
