Why wouldn’t I just give the clerk at the hardware store a $20 bill and get $8 back?
What I find to be insidious is not the particular method in itself, but rather the fact that teachers will be required to use it on a national level. Let teachers have the freedom to use what works for their individual students. Common Core has a lot in common with Obamacare. It’s a top down, command and control, one-size fits none system that will not elicit the best from our kids.
Except the teller would have handed the 10 back and then counted from 12 to 20...
Why would you give them $30 in the first place?
Why does Caleb mention Michelle Obama and big behinds? Doesn’t seem relevant to the point of the video.
So we should teach them to go through all those processes for a simple equation because it will help them make change as a cashier?
Is next class period’s topic Ebonics ...
Exactly. Common core is the tool used by the radical egalitarians to make every one , regardless of capability, equally unable to solve math problems in any rational, meaningful or useful way.
Smart kids are taught math is such a way that they become functionally math illiterate because the problem solving methods used are cumbersome and unworkable in the real world and as such have no functional advantage over other students who have neither the desire, inclination or ability to learn math skills
Consequentially, all are equal in frustration and students of all skill levels are equal in their inability to use math as a problem solving tool.
All except the ruling elites, of course, who are eventually taught real math skills to get the job done in the real world
The cashier gives back my $10, which was superfluous, and after punching my $20 into the register, tehy give me back another $8 in change—because that's what the machine tells them to do.
Oh geez. No, not all that to avoid subtraction.
So many issues here. I’m sure I’ll be flamed. This thread looks to have become a magnet for tin foil heads behaving like LIVs.
The video asserts that this is a “new, standard way” of doing a calculation. That’s totally wrong. It is not. It’s one example of a higher level of numeracy. It’s not a method it’s an example... just like you always expect when you’re learning. The hook or magnet for the ignorant is simply to assert that this is a “new, standard method” and those LIV types just believe that because they want to believe it.
Common core math is structured around the [erroneous] belief that kids learn simply by being exposed to higher level concepts and that no practice is required. Common Core is the complete opposite of learning by rote memory [for example, the individuals on this thread who say “where’d the 3 come from” were likely individuals who learned by rote.]
Learning at such a high level is great for kids who are really bright and motivated - but as aptitude and motivation reduces so must the methods for helping kids learn... simply a sliding scale. The brighter and more motivated a kid is, the more advanced/conceptual he can absorb and the less drill/rote he needs. The less capable and less motivated [most of what kids are today], the less advanced/conceptual he can absorb and the more drill/rote memory he needs.
So common core [math] is not what it’s being portrayed as - here on this video. It is misrepresented in hopes of eliciting a political response from LIV types who precipitously attack a bogus asserton. Later, posts from this thread will be extracted and used against us “wackos”.
Common core [math] is erroneously [note that I did not say it is evil, from the devil, etc] constructed around the assumption that most kids are super bright and super motivated. That’s bogus big time.
There is plenty wrong with common core - please pick something that’s actually wrong with it. This is silly.
It's not the teachers. They don't like CC either. They have to teach what the district tells them to teach.
They can leave and go to another district but all districts are being forced to teach this garbage and soon there will be no place to go to get away from it.
The US would never have gone to the moon with common core math - it takes too long. An abacus is quicker.
The only way to get around the politicization of mathematics is to get your kids out of government run education camps and into real schools.
“... to children who don’t reflexively know the basics,...”
Exactly! The basics become the mental equivalent of ‘muscle memory and as such form the basis of more complex calculations.
Have you ever noticed how fast the guy at the deli (usually the owner) used to provide change WITHOUT using the change function built into the machine? Back in the day, BEFORE the cash drawer finished sliding open he’d broken down the change to the number of even units and then the fraction then dug out the fraction and then the bills (usually in that order). He sure as heck wasn’t parading ranks of numbers around in his head.
College students learn????, oxi moron for morons
Amen FReeper.
If you give me a $10 and a $20 for a $12 item, I’ll give you back the $10 and figure it out from there.
Common Core is nonsense. Kids and people need problem solving skills. They also need basic math skills.
no problem with your explanation... but I will say that it is an adding fractions analog to the subtraction example in this thread.
Just an example.
By rounding to the next half decade.
Well, you ask a silly question, you get a silly answer.
Hooray for new math, Neeew math,
It’s so simple, so very simple, that only a child can do it.
>>I go to the hardware store to buy something that is $12. I have a $10 and a $20 bill, so I give the person at the checkout counter $30. This person now has to make change.<<
If it costs $12, just give the teller the $20 bill, take your $8 change and go home with your brain not fried.
