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.

Giving out receipts is the latest challenge for retail clerks. Now they ask you if you want one.
Two trains leave the station at different times traveling at different speeds. Which will arrive first?
Answer: look at the train schedule.
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.
Hey, kids, don’t sweat it. The government’s going to take care of you. Food stamps, welfare, free medical help, euthanasia.
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.
Like the old bus driver problem...
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.

Must memorize multiplication tables up to 12X12
Basic math is easy to teach, its all about how you approach it
I can understand the common core math methods instantly when they are presented as I sort of use many of these techniques "naturally" in my head. Others I see as perfectly logical, but with too many steps. There's a Allen West FACEBOOK post going around about 427-316 = 111 that no one seems to understand, but I easily see what's being done. I also understand the common core version of 32-12 problem discussed on this post as well, although it seems ridiculously complex.
So here's the question. Can a natural understanding of numbers that someone like myself possesses be "taught" through the application of these complex techniques? If the answer is yes, then I would be prone to support common core math. But if the answer is "not so much", then can these complex techniques, when combined with a post-modern approach of minimizing the importance of getting the right answer, serve the larger society?
I believe that what most people need is a way to deal with math, and the straight forward techniques of column-based addition, subtraction, multiplication and division have served generations of people extremely well.
But the cash register tells the checkout drone how much change to dole out.
Why even waste kids’ time with such a useless subject?
Their time would be better spent learning about gay history.
What idiot would give the clerk both a ten and at twenty when just a twenty would do?
It’s designed to destroy the American nation. If regular folks just don’t see that, they we’re all doomed! These SOB’ that are pushing this need to be rounded up and jailed for fraud!
Yes, I was a cashier before digital cash registers that tell the cashier how much change to give. That is how we calculated the change. And I was shown the method when I got my job. No need to mess w/regular math.
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!
