The bitching about common core would be nothing compared to this. We don't care about what's best, it's about what's comfortable and familiar. 

 

Our son did that when he was a little kid figuring math problems.  Now he's a computer engineering grad.

I guess so, cause he didn't get his math prowess from me, that's for damned sure.

I use the knuckle trick whenever I can’t remember if a month has 30 or 31 days

truth.

No offense, but how can an adult not remember if a month has 30* or 31 days? You've had 30 years and it's 1 data set with, what, 24 inputs?

 

* Or 28

It's sign language for "fuck you roundeye, we're gonna take over soon".

And they just might.

Two girls are playing a word game while adding all these numbers

Quote

As I mentioned in a previous post, a million Japanese children every year learn the abacus, which they call soroban.

The high point of the abacus calendar is the All Japan Soroban Championship, which took place earlier this year in Kyoto.

And the high point of the championship is the category called "Flash Anzan" – which does not require an abacus at all.

Or rather, it requires contestants to use the mental image of an abacus. Since when you get very good at the abacus it is possible to calculate simply by imagining one.

In Flash Anzan, 15 numbers are flashed consecutively on a giant screen. Each number is between 100 and 999. The challenge is to add them up.

Simple, right? Except the numbers are flashed so fast you can barely read them.

Is there some reason they can't picture the numbers in their head without all the flailing about?

The two girls in the post above yours are doing it in their head. If you search for "flash anzan" on youtube, there are lots of videos.

OK, as someone who did UIL number sense, that's pretty cool

I used the knuckle trick on your mom during "finger math" night.  30 or 31 days from now, she'll be telling you about your new little brother.
