Common Core Math Explained, in Youtube Video

My brain hurts.

But all our students will be equally confused and that's progress.

I have 2 kids in school, and so far from what I've seen I like Common Core. I get some of the criticism of it because it is different from how we were taught, but I don't think that automatically makes it a bad thing. It's developing some critical thinking which is great.

I can't link it from my phone but look up Arkansas mom obliterates common core and watch an even more convoluted method for solving a simple problem

Part of the problem is people watch a video like that and actually think it constitutes a valid criticism of Common Core. For a straightforward problem like 32-12, no one is going to work their way through that algorithm.

However, for a child to develop the numerical fluency at a young age to work their way through a problem like 32-17 in a multitude of ways instead of herp-derping subtraction with borrowing over-and-over again...it can be a powerful thing, and honestly is the way people who are actually good at mathematics think about computation anyway.

That example, I think, parallels how most higher-skilled mathematicians process such a problem.

For example, when asked to solve 532 - 274 I think a lot of intelligent mathematicians naturally would break that down into 32 + 200 + 26. That they won't have to after a certain period of time is a product of their success.

26285-15922 is not a rote matter. It's solved by such a deductive process I just described. The fellow in the video would have you believe that all substraction should be rote memorization or done in columns on paper. The 32-12 problem is obviously an easy one, but the important part is teaching the mental process.

Why is borrowing over-and-over again herp-derping?

It's dumbing down math. We read left to right, so logic would say we should add and subtract left to right, but no we've been taught to add and subtract from right to left. I figured out the fallacy in that around 4th or 5th grade, and scored very highly in math in high school and college.

I'm opposed to common core but this math issue is overblown. We use a homeschool curriculum that uses similar principles because it teaches a better understanding of how to mentally compute math.
