Quote:Common Core has a hidden assumption: that every small child has a Casio calculator with great big buttons. If that isn't true then the teaching of abstract word problems will have to wait until the child really can do with pencil and paper what a 6 dollar calculator does.

What the kid did wrong was change the problem from 427 – 316 to 427 – 361.
Then the kid really started screwing up :
427 – 361 = 427 – 3*100 – 6*10 – 1 became
427 – 361 = 427 – 3*100 – 5*10 – 1*20

This is not a new phenomenon. Those of us of a certain age will remember Tom Lehrer from the early '60's:
Hooray for New Math...

No, they totally didn't. That's what I meant by the "reverse engineering" line. We had to guess at the terminology they DID use too...
I think with things like that problem they were trying to make math less intimidating and break it down in chunks, but that only works if you are proficient at solving it the basic way first. I know because that's what I do in my head NOW. I break it up in chunks because-like my kid- I don't have the visual reference part for numbers in my head. Literally CAN'T see the numbers. They get lost between the seeing the paper and seeing them in my head and are messed up and incomplete by the time they get there. Welcome to dyspraxia!
The problem is that teaching that on paper is much more difficult than learning the standard way, and it's something you either figure out for yourself later, or you don't... I know several people who can only see the numbers and do the problem like they are writing on imaginary paper, I can't do that at all...
There is dozens of ways to do every problem, and that's what held ME up as a kid, waiting for my brain to come up with the most efficient route FOR ME.
I still have to count on my fingers for some things with small amounts, but large amounts are easy. Go figure...I've never been able get that one...
P.S. I hada use digital clocks until I was 12, too.

I don't count on my fingers, but for some paper and pencil arithmetic, I make 9 or sometimes 10 little dots on the paper, and count THEM.
On the large level here, though, the problem is the difference between ARITHMETIC and MATHEMATICS. The basic processes of addition, subtraction, multiplication and division, everybody uses them 100's of times a day: How many quarters does it take to do the laundry at the Wash-O-Mat? How much change should I get with my Big Mac? Can I afford ice cream cones for me and my sister and my friend?
Many fewer of us deal with: what is the area of that round piston, and how much force is acting on it? What is the area of this factory? If I gotta mix 1 scoop of Gatorade in 1 quart of water, how much do I put in a 5 gallon cooler? What is the length of that side of a triangle, without building it first to check?
Sometimes Math guys make Arithmetic harder, to teach the underlying Mathematical principle. May not be right, in the short run, or even the LONG run for that matter, but that's what they're trying to do. .

Math gene, runs in the family.
After HS, several times in my adult life, friends, relatives would ask me to
help them or their kid with the math. But I don't use math now near as
much as arthmetic ... half forgot it. So I'd begin by skimming thru the
chapter they were working on to refresh my memory.
Every time, the math book was different from the one before it & from
my HS books. They keep changin' 'em every few years. From my POV,
the simplest approach is best, so stick with the (old) books that worked.
KISS
How would they know which books worked?
In the years with the highest rate of kids passing math, those books worked.
I don't suppose the world was ever sane. (sigh)
... oooOO}{OOooo ...
I've given up looking for the meaning of life. Now all I want is a cookie.

A good article on the Common Core (in its defence):

It's not personal. It's just war.

Thanks KPO, I get it now. It's not that hard, just a break down I wasn't familiar with. I do stuff like that in my head & on my fingers all the time.

I think it might be good to at least expose the kids to these kinds of things in the more rural areas. God knows that in any city I've ever lived in that it would be a lost cause.
Meanwhile, that's what every kid in India and China and other "3rd World" countries are learning by 6th grade.
Fight them if they penalize your kid for it, but laud them for actually trying.
Collectively, we're fucking dum Wish.
I would have given anything for more intellectual stimulus back in those early days. Not now..... You can't teach an old dog, and all of that.....

HEY, I think my husband might have a word or two to say about that... Well, it depends if he's on his meds or not. He might say sure, have at it. I warn you all, I'm VERY VERY pale!
All aboard the Literal Train now!
EDITED TO ADD: I told my husband what you said and he said "Oh, it's one of those "we're going to eat grandma" vs "we're going to eat, grandma" moments.
And then he said "Not a dum fucking chance, bud"

Hehe Wish. I didn't get any of that. Granted, I'm drunk, but even though we all "live in the States", we don't all speak the same lingo...
Meds or not, most of us are dum.
My dad should be a saint. Somehow he stuck with his 5th and final Son and made sure he had the proper meds to keep himself from a padded cell to be as awesome a genius he could be on top of totally paid for Ultra-Premium College Education at a college where Warren Buffet is on the board.
I love my bro, but seriously dude? Fuck you. (I love you)
I must have been in the bathroom when God was handing out free rides to my Dad's kids....
Oh... you meant......
You dirty, dirty Vixen, you..... ;)
Props to Hubbs for a proper response to our juvenile fun here.
I feel no shame. :)
