I Really Don't Remember Math Being This Difficult

From a 3rd grade common core math workbook:

Or, you could do it the old, outdated way:

1 WTF? When would you ever need to do this sort of math in real life?

2 For when you get a government job?

3 My kids come home from school with this bizarre new shit a little too often... with terminology and methodology completely foreign to the way I learned. I'll show them my methods and they're like "Why didn't they just teach it to us this way?". Cause they're the same "educators" that will expel a kid for taking aspiring or pointing a finger like a gun... don't get me started...

Base 10 mental math has been around for centuries. I was taught this in the 1st grade in 1952 albeit with a less complicated explanation... 6+7=13 10+20=30 30+13+43. I still do this mentally with up to 5 digit numbers....but prefer a calculator...which allows me think about more important things. LOL!

5 Pro tip - avoid any aircraft, autos, trains, ships, buildings, or bridges built by clowns who learned this way.

Reminds me of the old Tom Lehrer song:

Hooray for New Math - New-ew-ew Math
It won't do you a bit of good to review math
It's so simple - so very simple
That only a child can do it!

8 That is the way i do math in my head, but it's something learned after years of practice, somewhere between age 10 and the ten semesters of college math I took. (yes, really.) It looks like "whole word" reading, which is what adults do but it's no way to teach a kid from scratch.

Dumb theory of teaching devised by Education Major who has never actually spoken to kids because they all have cooties.

9 Shirley you can't be serious? Progressive dickheads couldn't find their arse with two hands.

10 Know we know how the Feds calculated the "savings" of Obamacare. Seriously though, that is indicative of a very unbalanced mind. Perfect for the Federal Government.

11 RiverRat,
Your explanation makes sense. I still don't know what the heck they're doing in that example.

Why we homeschool Reason # 312.

12 26+17
can be broken down to:
26+10+7
Which becomes
36+7=43.

That's how my mind works.

13 wooga, mine too. That's the exact same way I did the problem.

14 @ 12 13- Me too. But I still used my fingers. And toes. This was a long time ago when I was more flexible.

15 That's actually a shortcut that's useful if you're good at math.

26+7=(26+4)+3 so 33.

I used it to do math in my head very fast. 26+58=((26+4)+50)+4 or 30+50+4=84.

Using that method to teach to beginners is idiocy.

The problem is that many school administrative types aren't good at math, they remember how hard it was to learn so they're trying to make it <i>easier</i>.

So we have high school students who can't multiply 5*9 or add 36+87.

It's depressing.
