College Students Learn Common Core Math (video)
conservativevideos ^

Posted on 03/21/2014 11:13:57 PM PDT by chessplayer

College students and others at George Mason University were dumbstruck by the tedious nature of an elementary level Common Core problem during a short series of interviews conducted by Campus Reform last week. The problem, 32-12, was demonstrated to those on campus the traditional way and juxtaposed with the Common Core method.

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.

I don’t get any of it ...

I get the 12, where do you get the 3 to make 15

Assuming 15 is right, where do you get the 5 to make 20

Assuming 20 is right, where do you get the 10 to make 30

Assuming 30 is right, where do you get the 2 to make 32

Or any of the other numbers that aren’t 32 and 12?

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.

All there are doing is adding to 12 to get to 32. Guess they figure our kids are to stupid to subtract or our teachers are to stupid to teach subtraction so they just teach addition. How much do I have to add to 12 to get to 32 is the same as 32 minus 12.

If the item costs $12, why would you give the clerk a $20 and a $10? Why not just give him the $20?

Let's make the problem what actually happens. I go to the hardware store to buy something for $12. The clerk scans it, I hand her a credit card, and the register spits out a receipt.

The process you're describing was automatic for us before the advent of technology because we were drilled in fundamentals, and knew the addend or subtrahend of any two numbers since second grade, cold.

When you concentrate on conceptual mathematics to children who don't reflexively know the basics, you are wasting your time, just as you have wasted your time with a contrived example.

If you give the teller a ten and a twenty for a twelve dollar item if are either having a very bad day or you are an idiot.

Umm. Its only $12 for the purchase. I'd only be giving the $20 in the first place. So, it would be 12+3+5 but this is too complicated.

Without using traditional subtraction:

20 is a decimal count, 2 units of 10. 12 is a decimal count of 1 unit of ten and 2 units of 1. There are 8 units of one between the decimal counts.

8 is the correct answer. The teller has a fiver and 3 ones, that is the change.

QED.

If the item cost $12 and you have a $20 and a $10 why would you give the cashier $30? Since there is no $30 bill? I don’t know maybe they do things different in your part of the world.

Because they use common core math so they give the extra money so the cashier can give the correct change.

Why the hell would you give more than the $20?

Your explanation of CC math is severely flawed.

They probably use multiplication to divide, first we turn all these numbers into fractions class and then...

"I don’t get any of it ..."

I think they're trying to get the answer by adding up the difference between 12 and 32 in incremental steps. So the starting number is 12, and they add 3 to get 15. Then they add 5 to 15, to get 20. Then they add 10 to 20 to get 30. Then they add 2 to 30, to get 32, the ending number. Then they add all the individual results (3+5+10+2) to get 20. It seems very arbitrary.

Excuse me. If I’m working the counter and someone hands me a 10 and a 20 for a 12 purchase I grab the 20 and give them 8. I never touch the 10.

Your example does not work.

If the customer says he really wants to give me a 10 and a 20 for a 12 purchase because he is a common core lover, I point him to the sign that says we reserve the right to refuse service to idiots and kick them out of the store.

I taught a teenager long division a few years ago. She showed me how she was taught to do division and I was dumb founded. I majored in math and I had not the slightest idea of how she was supposed to divide. It took me two hours of pounding into her head how to do long division. While I was teaching her I realized she could not do multiplication. If you can’t multiply division is really hard. And she was an honor student! Can’t do 6th grade math and you’re an honor student in 11th grade? WTF!

The good news for me is it don’t matter how they try and teach my grandson math. I couldn’t help teach him math past addition and subtraction. I fail when it gets to the level of fractions.

Your grandmother is good at math, ask her.

In fact, I think I’d just tell him to fail the class if he is having trouble with it and focus on a subject he likes.

Someone taught with Common Core methods would probably add twelve plus ten and give you $22 change.

Giving out receipts is the latest challenge for retail clerks. Now they ask you if you want one.

fractions are easy if you are adding or subtracting just find the common denominator. A fail safe method is to multiply the bottom of the faction to get a denominator and then cross multiply from bottom to top.

Example 1/2 + 2/3

multiply bottom 2 x 3 = 6 so 6 is the denominator

now cross multiply bottom to top

2 x 2 = 4 so we have 4/6

3 x 1 = 3 so we have 3/6

now add 4 + 3 = 7

so our answer to 1/2 + 2/3 is 7/6

easy.

One more example

11/13 - 5/8

13 x 8 = 104 so 104 is the denominator

13x5 = 65 so 65/104

8x11 = 88 so 88/104

88 - 65 = 23 so 11/13 - 5/8 = 23/104

23/104 is meaningless to most people so

23 is pretty close to 25 and 104 is pretty close to 100 so 23/104 is pretty close to 1/4 (25/100) but since we had to grow 23 to get to 25 and shrink 104 to get to 100 we are really looking a something a little smaller then 1/4. Call it almost 1/4.

What common core is trying to do, and I’m assuming a positive intent when I say this, is to speed up the education process by skipping over more basic steps and hope the child will figure out those basic steps on their own.

However, it will be a disaster. If you take a look at older textbooks and compare them to the present, it is clear that the amount that children had to learn has been falling steadily for the past 50years. We’d be better off if we could throw out every math textbook and just reprint the one from the 1950’s.
