What's wrong with teaching kids how base 10 works?
One of the things I hated most about school was rote memorization. It's much more practical to understand how and why things work.
Saw the video.
Yikes.
What is so hard about taking a 9 and adding a 6 to it. Their way looked more complex. Break the 6 down to 5 + 1. That works great unless you are adding it to something other than a 9. You have to take x (x = 9 in this case), subtract it from 10, then subtract that difference from y (y = 6 in this case), and the difference of that calculation added to 10.
That's damn complicated to me.
Don't get what they said about memorizing 9 + 6 = 15. If you don't understand how to take 9 and add 6 to it and get 15, then this new process is going to completely blow some kids mind.
Don't think this is going to do the average school kid much good.
It may seem dumb when looking at something as simple as 9 + 6, but it can be very useful when applied to more complex problems.Quote:

First, I've never been taught the method in the vid, but its what I've done in my head since I can remember, and it takes a fraction of the time regular math takes when the numbers get bigger. It quickly becomes very intuitive, and fast.
But never mind how good or bad this teaching method is (because God knows the 1 minute video wasn't exactly made to be informative), lets tie this in to Obama even though the program started before he was in office and he had nothing to do with the actual standards in place in the program, not to mention the program has had bi-partisan support (and bi-partisan push-back) from the get-go, including notable conservative supporter Jeb Bush (which matters because its the Governors who set the standards, not the President). Left wing fail? Get a grip, and maybe learn a bit more about what you are criticizing.
Good lord Tony, shut it down and enjoy the day. It's fucking Super Bowl Sunday, your team is in the game, you are a stones throw from the fucking place, and you are posting bullshit like this? C'mon, man!
OMG!!!!! Now I understand why my grandaughter is having a tough time with math and she is exceptionally smart. This is so ridiculous and makes me very angry that it is being shoved down our throats.

But if you tie it to Obama, then it's definitely evil. Just because these people have no fucking clue how any of it works doesn't mean that they can't be angry about it. Here in reality, Common Core is actually a pretty good example of what Libertarians have been asking for, more authority at the state level.Quote:

I think it's funny that you people are raging over this. Ask anyone who is not a prodigy that does mental math and they'll tell you they do the same thing. I do this all the time when I'm doing multiplication, addition, or really just any math in my head. It's very commonplace to solve problems by using a set of rules to change the problem to something you're more familiar with.
I actually use a similar system for squaring two digit numbers (I use a base ten system) so I can actually compute it without a calculator or even paper.
eg.
what is 22 squared?
10x20 plus 10x20 plus 22 x2
22x10=220 plus 220= 440 plus 44= 484.
No one ever taught me the above. I learned it on my own when bored in history class. But it goes to show just how naturally our minds adopt a base ten system.
Here's an interesting thing about base 12, and why it might be better. Pretty longish. http://io9.com/5977095/why-we-should...ounting-systemQuote:

I can't go for Base 12 because then you're using A and B as numbers, and I just can't accept that.
Don't you have a degree in Computer Science? A through F are numbers in hexadecimal.Quote:

When did I say I liked Base 16?Quote:

I imagine rollercoaster design would use calculus heavily. Maybe I misinterpreted though and you are using it as an example of a profession that does.Quote:
