where did they get the 3 from in the first line?
all that to avoid simple subtraction??
they’re doing everything they can to undermine education in this country. the result will be more people in need of govt assistance.... more people on food stamps and welfare... more people voting for democrats to insure they get it
just remember, democrats gain voters as more people end up on welfare and food stamps.
Here’s the thing, we all already do this kind of math each and every day. Knowing how to do this is quite useful.
Let’s make the problem a bit more likely, though.
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.
The teller grabs 3 $1 bills and puts them on the counter, and says, “12 + 3 is 15”.
The teller then grabs a $5 bill and puts it on the counter, and says, “and 5 makes 20.”
The teller then grabs a $10 bill and puts it on the counter, and says, “and 10 makes 30.”
The item is $12. I put down $30. The teller counted out $3 + $5 + $10, or $18 in change. WHICH IS THE CORRECT ANSWER. This is a real life example of what happens in hardware stores across the country each and every day.
Just because you do not understand what is being taught does not mean that what is being taught is useless, confusing, or pointless. I am NOT defending common core. What I am defending is teaching children how to do the same kind of real-world practical math that we do every day.
That is cumbersome and stupid
Keep It Simple, Stupid!
Hey, kids, don’t sweat it. The government’s going to take care of you. Food stamps, welfare, free medical help, euthanasia.
Balancing a checkbook is going to be very complicated in the future. Ditto doing ones own taxes. Quickbooks and all the other accounting software is gonna get more complicated too!
Why does Caleb mention Michelle Obama and big behinds? Doesn’t seem relevant to the point of the video.
College students learn????, oxi moron for morons
12+3=15, 15+5=20, 20+10=30, 30+2=32. . so 3+5+10+2+Food Stamps = $32
Another argument in favor of homeschooling.
This is absolutely ridiculous. Math tables work. Repetition works. The basics by rote works. Build the foundation and the rest follows; at different rates for different students. But, it follows.
And now we have common core...another libtard trip down the rabbit hole, where up is down and in is out.
I was lucky not to be of the Sesame Street generation. Because what is taught in Sesame Street never grows up beyond kindergarten, or maybe first grade level. Once children know the few basic things they teach, it is utterly useless to them.
Government directed education always teaches to the very lowest rung of student intellect. Not even to mediocre students, and certainly not to intelligent students. With government running things, students would have no more knowledge in sixth grade than they learned in second grade.
Common Core is a disturbing looking into the minds of Affirmative Action government employees.
Now...try analyzing a government budget with common core math!!!
Back in the late 60s the ‘new math’ was introduced. my 4 year older cousin was teaching it and tried to explain it to me, I was in college working on my history degree. My comment to her was: “you are trying to teach advanced math theory to elementary school kids before they know how to do basic addition, subtraction, division and multiplication.” She said yes, “we must do this so that we get them fully trained to be future math experts.” my reply was ‘Your philosophy is wrong on this, you are putting the cart (Descarte) before the horse”
To paraphrase John Wayne: “Math is hard. It’s harder when you’re doing it stupidly.”
