I'm one of those losers that love it.



Not because I initially understood it either.

They're trying to teach a way to approach numbers in one's own head. You ought not to be slashing and carrying ones over in your head.

I get their reasoning for it. The way we're used to is faster on paper, per se, and best taught afterward.

Doesn't solve our educational problems though...

Just talking about math makes me dizzy.

I have to take calc this semester and I'm not looking forward to it. :(

On the subject though, I don't think universal methods are bad, but we need to make it possible for those who learned the 'old' methods to grasp it easily too. Just my opinion.

I think maths is good if taught correctly, but without that it turns into a waste of time teaching people something they only know how to use in one situation. I think its much more important to teach people how to use the tools across a wide variety of areas in the subject that maths provides them with rather than just using them for one specific application. And also how these methods are devised and the reasoning behind them because when you know that you can begin to understand problems on a fundamental level and that makes it much easier to grasp other problems.

Each to their own. I used to do long division in my head, on post, to pass the time. I'd just come up with random numbers, like 594,789 divided by 534. After I'd finished I'd do it out on paper to make sure my answer was correct.

I NEVER used the common core math version.

And, my 10-year-old step-son asked me what 32-12 was the other day. I told him to get the answer himself.... that should not be challenging to him. He asked for a pen and a piece of paper, and then was counting things out on his fingers for 5 minutes. Worrying, but he doesn't live with us, and we only see him every two weeks or so, for a couple days.... so there is little we can do.

I certainly get the issue with it. Comprehension isn't easy. I didn't 'click' until middle school myself.

Their common core division method actually makes sense for mental math too. The concept is nice...but is it being introduced too soon where its 'preparation' is labored by the 'frustration' it delivers....entirely plausible.



I get that they're trying to get kids used to throwing numbers around and per se 'getting it sooner' but push turns to shove. It may just be too soon even though ideally 'sooner' may be preferred and make it easier later.

Funny. I'm not sure what that "frustrated parent" is on about. The idea your images show is to split the problem into big known numbers (100, 10), and remainders. That's.. pretty normal. It's what we do when we make change (87 cents? Okay, that's 3x 25, 1x 10, 2x 1, which requires jumps of known levels). Guess that math degree, earned well before Common Core, is serving me well when I buy stuff... and in calc, and in diff eq, and in my career, and...
