I'll be the first to admit that there are some parts of math which are taught badly or unintuitively. But the listed new method just seems like a solution looking for a problem. Sure, it's easier to show your work, but it seems much harder to visualize or do all in your head.

I'll be the first to admit that sometimes I don't understand what my daughter brings home. Especially when the problems ask for an explanation. But at the same time I see her doing things like division in 1st grade (it's masked as something else, but it was definitely division) and I really just think there's a lot of butthurt parents out there who think all kids learn the same, which was how things were done when they grew up.

Honestly, i can't make heads or tails of how this supposed "new way" works. I've never even heard of this. Can anyone explain it?
Also, shouldn't it be "old-fashioned"?

Here's my guess:
Start at 12, add 3 to make it 15 (divisible by 5).
Add another five to get it to next number divisible by 5 (20).
Add 10 to get it to 30 (last number divisible by five).
Add 2 to get to desired number (32).
Take all addition numbers (+3, +5, +10, +2) and add them together to get answer (20).
I tried it again with a different equation:
57 - 14 = ?
14 + 1 = 15
15 + 5 = 20
20+ 35 = 55
55 + 2 = 57
1 + 5 + 35 + 2 = 43

The old way vs new way picture makes me think of the difference between using the metric vs imperial in terms of length conversion.
One being easily convertible between 10s and you can do most of it in your head or with a line on a paper, the other requires fraction equations.
I must be old, because looking at that math paper, I can't help but think that the old way is better.
