Common Core Math Question: How Does 8 + 5 = 10?
Pundit Press ^ | 10/10/14 | Aurelius

Posted on 10/10/2014 9:28:56 AM PDT by therightliveswithus

Imagine you are a student doing math work. You've gone through a number of questions, and you feel you've really got the hang of everything. Then, all of a sudden you get this question: "Tell how to make 10 when adding 8 + 5." What do you respond?

That was the problem facing a young student learning how to add using Common Core. The student responded with confusion, answering the same way most of us would: "You cannot make 10 withe [sic] 8 + 5."

The student was told he was wrong.

Underneath, his teacher wrote, "Yes you can. Take 2 from the 5 and add it to 8 (8 + 2 = 10). Then add 3." But wait, if you're adding three, it's not 10 any more... It's 13.

And why does 5 need to be broken down? Why not 8? Why not turn 8 into 5 and 3, add 5 plus 5, then add 3? Still, though, 8 + 5 will never add up to 10.

You can see the question, student answer, and teacher correction below:

This is insane. And only making real math, the “core” of the issue, more complex for zero reason.

Blacks and whites are now the same; neither can do math!

On that basis you can make any number you want.

In a base-13 number system, 8+5=10. Hmmm, maybe Common Core is really for brainiacs and riddle solvers?

A misguided attempt to teach critical thinking, without exposing kids to political thought other than that prescribed by the regime. You know the old math saying, “There’s lies, damned lies, and statistics”.

A national movement to start firing all these idiots, admins, “teachers” and politicians associated with this.

Clearly you don't understand the mission of 21st century education in the US. We're not teaching kids to be productive members of society.

We're creating dependents who are incapable of knowing the difference between million, billion and trillion, and who will vote with their hearts rather than their brains.

O-bots, in other words.

When the state tells you that 2+2=5...

The reason is to dumb down the electorate even more. Too many of them are educated and smart enough to see through the leftist agenda.

This is ridiculous. Let’s take a simple addition problem and make it into a subtraction operation and 2 separate addition operations.

5-2 = 3
8 + 2 = 10
10 + 3 = 13

Yeah, that’s a lot simpler than just 8 + 5 = 13. /s

Huh?

What is the purpose of that question?

The extra three is graft that goes into Obama's pocket.

Now I understand how the administration calculates the unemployment and inflation numbers.

Tell how, when you have 92,000,000 people in a nation of over 300,000,000 not working, you get an unemployment rate of 5.9%.

You take 92,000,000 and remove from it 74,000,000 which gives you 18,000,000 which is roughly six percent of 300,000,000. Common core! Whoo hoo!

I think its completely on purpose. Same w/ reading and writing. The more unintuitive and unnatural it becomes the less students actually learn. In the end it weakens the nation. Think for a moment about the guys who put men on the moon. They weren’t burdened by ‘new’ maths and all the boutique methods of teaching (or not) reading/writing/geography/etc. These guys understood the rudiments of math and science and had few quick aides to complete the calculations. They also were able to think critically.

Using that logic, you can also make 5, 6, 111, and -46^^3 when you’re adding 8 and 5.

But it just fits in with the PoMo philosophy that everything is whatever you want it to be.

Where did the 2 come from?

Typical liberals, making things up from thin air.

Poor kids will be terribly confused.

Reinforces my developing theory that Common Core math is about sophisticated reasoning, taught by the unsophisticated to the novice. I see what they’re trying to teach, but it’s something that can’t be grasped until primitive steps are learned, internalized, and made intuitive. In this case, someone had a half-baked idea about using insights to juggle values to compute a result from a starting point, but completely missed the point (and goal) and is too self-important to admit (or even recognize) the miss.
