Common(unism) core? I don't even understand what they're doing in the first set of boxes. Just looks like they're trying to make math harder by making the process more cumbersome and slower.
They did the same thing with reading, look up three cueing, it’s how they teach reading in common core, it’s supposed to be “how our brains understand language” but it ends up making kids functionally illiterate
My age group didn't have this shit. It looks like it works better for actually doing it in your head for a rough estimate (unless your memory is very good) but on paper the tried-and-true method obviously is the right way.
Leftists like to take an idea, make it their own, and pervert it to have it seem that what they say has a basis in reality.
I actually get what they are trying to do. They're trying to get people understand what is going on behind the equation. The idea of hundreds vs tens vs ones place. It makes sense for getting kids to understand the concept, but it's not practical for long hand written equations. I actually used this method a decade before common core was a thing, I just did it mentally, never thought to map it out like this. Essentially, the old school way of doing multiplication is just common core boiled down to it's core ingredients. CC is attempting to reinvent the wheel.

Simpler then that. Textbook companies wanted an excuse to print a bunch of new books.
Funnily enough, after analyzing it, it's the same thing as normal multiplication except backwards and with boxes.
Precisely, what I meant is that their method DOES work IN ONE'S HEAD but for a rough estimate because nobody is going to remember every step.
It's the same as actual math, just with extra steps and communism.
Literally LOLd thanks

Who gives a crap when everyone in the real world uses a calculator
It's called Lattice
I remember this bullshit from elementary school.
it just makes it slower.

No, this is not lattice, lattice is way different.
This is the area method, which is actually quite useful for factoring polynomials.
They're just getting kids reliant on their Iphones so they can't survive without them. Mark of the beast. No buying, no selling, no Iphones.
