re: How dumb do you have to be to not understand common core?

The irony of saying kids are too lazy to memorize is outstanding. Memorizing is the lazy way. Math is not meant to be memorized, it is meant to be understood
I disagree.
As an engineering grad, math is meant to be memorized, the laws of thermodynamics are meant to be understood.
If i made a math error but had the right formulas and would have gotten the final answer correct had it not been for the silly math mistake i made, teachers would rarely take any points off for something like that.
If you didnt' know how to do integrals, then tough shite, find a new major. I've taken many of math classes in college, made an A easily in every single one of them with very little effort. It was odd if i didn't get a 100 on the majority of the tests i took throughout the calc classes and diff eq. Math is repetition and memorization to me. There is very little thinking to me when it comes to math. You either know it or you don't. There's no critical thinking needed to figure out math problems, it's just plugging in numbers. I dont' even understand how people study for a math test. I did the homework and understood it. If i can do that, then i know the material.
Why do i really need to know how to mulitply 43x231? every working person on the planet plugs it into a calculator. And the smarter we get the more complicated the formulas we can input into our calculators and computers to do this simple math shite for us.
The only people in this world that need to understand advanced math principles are math majors and a few physics/engineering doctoral degrees. The other 99% of the world is just fine understanding math with a calculator.

I'm not here to say common core is better than the old method. I really don't know which is better and I don't care.
But I can't help but lol when people post about how confusing common core is. Maybe it's more difficult than what they post. I've seen two memes of subtraction problems posted, and with no prior knowledge of common core, I could easily see the logic behind the method. Yet everytime it is posted somewhere, parents don't complain about how the old method is better, they say they don't understand common core altogether.
58-27=?
27+3=30
30+20=50
50+8=58
Answer is 3+20+8=31
Again, not here to say this method is better. But, from someone who figured this out from two equations in memes and nothing else, if you don't understand the math behind it then you just don't get math.
And if you don't understand it's fricking stupid to do 4 extra math problems just to figure out that 58 minus 27 equals 31, then you just don't get common sense.
Common core is pure horseshite and whoever came up with this stupid idea should be beaten like a rented mule.

so to get the 31 in the first part above, you had to do some sort of math in your head. How does a kid get here without all of the other BS after that?
It's done in your head here because all you have to know is what 2 numbers make 10.
Simplify the problem.
11x12
That takes counting and addition, counting and addition with place holder rule, and addition of a 2 and 3 digit number.
That's a lot of steps that you can't do in your head...YOUR WAY.
All common core says to do is to make that 11 a 10. Multiply that by 12...which is easier. 120. Then add on the extra 12 from the 1x12 -- which is easy again. 132.
YOUR WAY
11
x12
____
2x1 and 2x1
22
0 and 1x1 and 1x1
110
22
+110
____
132
Now make this without ones and twos and it gets more difficult, but stays the same difficulty level in common core.

If you have 58 of something, and you take away 27 of them, you are left with 31 of them. Why do you need to got through all of the other steps to do this?
They appear to be teaching manipulation of numbers, which leads to being more numerate. I had a teacher who was all about this when I was at school 20 years ago (age 11-16), I'm the most numerate person I know, it's probably a PIA for most of the kids though.
My daughter is in 3rd grade and some of the terminology they use for math is baffling to me, not to mention I'm usually able to point out much quicker methods, it's weird and frustrating, but I'm not set against common core, just perplexed.

Good post.
Math is knowing which calculations to apply, arithmetic is actually applying them. Getting your math right is ultimately more important, but you'll always look wrong when the arithmetic is wrong.

nly a complete retard cannot see the value in the new math. I wish I had been taught that way as it would have completely changed my perception of numbers.
Actually you're the retard for not using the concepts taught in common core on your own. Once I figured out what the hell they were trying to teach I realized it was common sense. I didn't need to be taught to group large numbers into sets of 10 or 100 before adding or subtracting. That shut just came to me because I'm not a retard.
The problem is that our teachers are all left brained sorosititutes who don't have any common sense. Our teachers are the problem, not the methods of instruction.

OP should have used 57-28
It better shows the point of new math for the neanderthals.

I would like to know the results of the test scores now using CC vs the old way. Is it really an improvement?

Agree completely. In the business, engineering, and trading world (areas of my life where I use math) it is a huge advantage to have simple math memorized.
If something is complicated enough where the methods taught in common core could be useful, the work is going into excel or a calculator.

It's not about grade school math test scores, it's about understanding numbers and processes when math gets more difficult.

Well, is it working? I don't really care one way or another as long as it helps.

It's been around for years and in many cases is taught in conjunction or perhaps before memorization or other techniques of learning how to use and understand numbers.
It's not stunting kids math growth. And too many kids are opting out to get true data, plus this will need years to come to fruition.

I admit it, I have no doggone clue why you did any of that. What on earth possibly lead you to add 3 to 27, 30 and 20, 50 & 8? I'm serious.
