so... they teach kids what's actually happening in the math problem they're solving?

the horror!

No joke, the way CC proposes to add those numbers in the image is pretty frick'n stupid.

I add numbers in my head first by grouping them in tens, and then adding the singular numbers like that, yeah. But it's just my preference.

I don't feel like I need some bunch of government bureaucrats to tell me how to do that.

kids who learn common core could understand why - or how

 

[Unkotare]

Students who come from places where they are still taught (told) to "just do it" and to do it over and over and over and over and over and over without a word about "why" are often years ahead of their American counterparts in math skills.

This sounds like somebody wants to make 3rd graders into PhDs in Number Theory instead of learning to add and subtract. Sometimes you just gotta put your head down and work; a notion that runs contrary to liberal orthodoxy.

 

[Ame®icano]

Common core is complex math theory distilled for children, giving them a complex understanding of pretty simple topics.
Just more self serving edu bureaucracy, imho.

the horror!

Look I have no problem with this teaching method...ONCE the fundamentals are learned.
after all NOT one of us can multiply 3,333,231,233 by 1,123,111,222,111 in our head for sure ... that's what calculators are for!
But when it comes to simple math 28 x 30... I never remember it was 840... I just learned how to multiple.
These kids are too young to learn how I just did.. they just need to learn 10 X 10 equals 100.

This evening, I purchased a pint of whiskey which I knew beforehand cost $11.73 (tax included).

So I handed the kid $22.

The bitch went into vapor lock, kept the 20 and handed back my two one's.

The result- Instead of giving me back a $10 bill and change, he peeled out $8 and change. I was simply trying to save him from dispensing un-necessary $1 bills in change.

I worked cash registers in the ought-70's when those registers were incapable of telling me the change due.

So we did the math. Not "new math" , not " common core" math.

Just math.

Fucking Liberals... give them an inch, and they'll take that inch and give you a trunceated icosahedron with plybars.

1+1 can never = 2 to Liberals.

The fundamentals were already present in the old way. In example above, common core is trying to eliminate subtracting by justifying that adding is less complex. There are many ways to get to the result and there is no wrong way if result is correct. Our centralized, liberal, socialist edu is trying to force their way as only acceptable way. See picture.

It makes sense, right?

Well, it also make sense to convert it to binary so you only use two numbers. It would also make sense to convert previous example to base 12 and still get easy way to correct answer. But no, common core is something they want because it justify their self serving existence.

Once the rote learning is completed, then begin the abstract conceptualization.

Absolutely correct! No question... learning when capable of abstract functions is totally valid!

They've been using 'regroup' for decades.

Wow... had to look up the term "regroup"..Cool Math 4 Kids Addition Help - Addition Lessons - Adding Two Digit Numbers with Regrouping Carrying - free online cool math lessons cool math games fun math activities math flash cards to print calculators and more
and it is exactly how I learned to add/subtract 60 years ago when I was 11 years old.. "carry the one!!"

Why would anyone object to that answer

Knowing how a problem is constructed and alternate ways to reach a solution helps you solve problems in your head. Good skill since most of todays students can't do math without a calculator

Look for the majority of educated people like me over the last 70 years we learned by rote tables BUT when we were capable learned how to use relationships, i.e. 81 + 39..= 120 (carry the one!) . It will be interesting to see how long the common core methodology lasts with the measure being will a kid learning Common core method be able at age 71 to add in their head "81+39"....

Learning by rote is an abuse of math
Math involves fluid thinking and creativity. More than one way to skin a cat

Learning by rote and memorization stifles that

This is new? lol, enjoy satirist Tom Lehrer's bit on the 'new math'

You would still need to learn Boolean Algebra to learn how to calculate binary code..
