They are trying to avoid borrowing. They're libtards. Of course they want to avoid borrowing. Borrowing implies that something must be repaid. They want free stuff. So until they can come up with an entitlement theory for mathematics, they'll just skip the concept of borrowing and teach how to take ... in three subtle phases.

This is actually a form of reasoning, rather than structured process - Which I applaud. But the reasoning is so convoluted that it is barely useful.

We're dealing with the same crap with my 4th grader. The example above has turned 30 minutes of homework into hours of homework. The result is that the kids end up hating math - exactly the opposite of what the new standards were supposed to promote. It's also dumbing them down. My 4th grader is three chapters behind where his brother was at the same time when he did 4th grade just three years ago.
The real problem with CC comes when you find the time to look at social studies or what passes for sex education. The books they use to sexualize such young children will make you want to get your gun. The next School Board meeting should be quite the event.

Or just do the math in your head like I did in about 5 seconds. And that from the gal who made an F in Math 105 at FSU and had to take it over for a D. :-)

It’s easier to do it in your head. Take 568 and round up 293 to 300 and subtract. You get 268. Now add back the 7 you added to round up to 300 and you get 275. I did it two seconds in my head.
It would be easier these days to just tell the kids, “take out your smart phone, hit ‘calculator’ and do the problem”! lol

Many private schools have adopted the Common Core Curriculum as well. My daughter solves it the old fashioned way and reverse engineers the answer to how they want it.
To: therightliveswithus
I actually use a similar system in my head, when doing math. I’ve gotten very good at it (knew the answer to this question in around 2 seconds).
And I can usually ‘beat the calculator’ with the kids when the numbers involved are less than a thousand.
However, ever since I was very little, I have realized that my method is ‘backassward’ to most people. Any attempt I have ever made to teach it to people has failed, and I certainly wouldn’t put it in a curriculum.

1. Common Core is universally despised by ALL of the teachers. 2. All references to the founding of our country have been removed and replaced with the grievances experienced by various "minorities" 3. The amount of busy work, or the load put on their shoulders has increased to the point of breaking almost all of the teachers, especially those that care about doing a good job. 4. She, and the other teachers, give it no more than 3 years before it fails like all of the other fad education crap that has been foisted on Education here in the US.Sounds like the Operational Manual for every Czar, Obamacare, and Dept Head in Obama's WH, and everything in his Administration.
Like Common Core, this will all Freeze up and be lunched, like an engine run without oil...

Yup! They only truly understand borrowing later in life, like for college.

My personal solution was similar to yours.
293 is 7 away from 300, so add 7 to each number.
568+7 = 575
293=7 - 300
subtract 300 from 575, you get 275. done.

Heh. I did a similar thing. I added 7 to both and then did the much simpler subtraction.
