no but i can recall what 8x4 is, and i can recall what 8x2 is, and what 1x24 is, and i can recall how to add, so there's that.
That's what common core teaches.

There's no science behind how multiplication works. 18x24 is 423 b/c it is, just like 2+2 is 4. Math is simple.
Except that 18 x 24 is 432.

Memorizing tables does nothing to promote analytical thinking. It's why children fall behind once they get to higher maths
they fall behind b/c they aren't smart, or they are too lazy to learn.
Doesn't matter how you teach math, you either get it or you don't, and that's b/c regardless of how you teach, you have to memorize numbers and your basic tables to do whatever why they are teaching how 18x24=432

well that sucks. i guess i'm done.
on a side note, had i been taking my Fluids final, and i made this mistake on one of the problems, zero points would have been taken off for that error, assuming my final answer was only wrong b/c of this error.

Trump supporters hate common core; they didn't need any of that silly learnin in school and now they can afford just about any tattoo at the best parlors.

The common core method is much better.

This has got to be a joke right. I'm pretty sure that is what I said.

I'm not saying don't memorize tables. What I am saying that it is beneficial to understand it as well for more complex problems.

We were taught base ten way back in the 80's. My first grader seems to be perfectly able to understand this "new" way of addition.
Now, when they start teaching binary in second grade.....

this is wrong to an extent
if you comprehend what the numbers are doing when they interact (via addition, multiplication, etc), then you don't have to memorize much. kids who rely on memorization too much have major struggles with very simple concepts like fractions. since they don't understand what they're doing, when you get outside of the very refined boxes of the rote memorization, they get frustrated and fall behind.

If you want math to be simple for kids just go ahead and teach solely on a calculator, if you want them to learn math then simplest isn't the best option.
Good point, but it really depends. I strictly meant simple multiplication/addition/etc. When you talk about foiling/anything to do with polynomials, there is a much different approach to problem solving. I just think it's stupid to do (2+2)(2+2) instead of 4 x 4 (yes, I was shown this foiling method way which my teacher in high school referred to it as Singapore math.)
To me, the fastest, most efficient way of solving math problems is the best. I know that way of thinking isn't for everyone, but I feel as if common core is a way of beating around the bush when you could easily solve problems much faster through older methods.

The other use of common core is the 'common' aspect of it. Everyone has to use it, no choice in the matter. It's a way for government to standardize education and run it like an assembly line. Ideally you teach every kid this way and it works. But that's not how education works. Different kids need to learn in different ways, and the best way to do that is more individualized teaching. Smaller class sizes with more attention for each student and more creative teachers that can change their lesson plans to fit the needs of their students is the best way to teach

The best way to describe it is that it lowers the ceiling but races the floor. It holds back smarter kids but helps kids that are not that smart.

And like I said, the fastest way to do it is on a calculator. But in the real world, when your "problem" isn't written on a piece of paper and you have to decide a formula to use, you will need more than a calculator or the simplest method.

Which method are you advocating for that works better than the simplest methods?
Posted on 9/18/15 at 12:17 pm to KindaRaw
Understanding equations and math to solve problems that are written down on a piece of paper and don't work out perfectly to whole numbers.

Common core is an educational framework that focuses more on critical thinking than rote memorization.
I know that 9x8 is 72 because when I was a little kid in math class I memorized it with the rest of the multiplication tables. Why does it matter if I can't take 9 steps via some convoluted and confusing method to show you exactly how I got there?
