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.
Commies are deconstructing western civilization....even the most basic STEM education is being dumbed down to 4th world sand-scratch levels ( but as long as we all embrace SJW hate whitey it's all good they say)..🙄
Just to be clear though, what's on top is supposed to help teach you how to do math in your head, the way most of us always bitched in school about "when would we ever use the stuff", well the top is supposed to help you in doing math mentally without pen and paper where the bottom is much more difficult to do in your head.
I'm not defending common core at all... However, i understand why they tried it, they just went about it in a completely retarded way. I'm just helping explain why it looks like that when you actually write it out..
the idea is to teach you how to break numbers down, and math problems down, in your head with whole numbers that are easy to keep organized with practice. once you get it you get it, but it's sometimes very hard to get for people who didn't learn that way from the start, and that's where parents from our generations and older have such a hard time.
Understand your explanation. When you get to the end, though, you are not doing this in your head (you're writing it down with pen and paper) and you still have a large column of numbers that summing in your head is not easy.
The second method you still have to remember your multiplication tables but the columns of numbers are easier to add.
Yea.... it's like someone who understood the goal helped form the idea, but then a bunch of people that have no fucking clue how to do it wrote the rest of the math curriculum for common core and completely butchered it........
If done correctly, released correctly, and also correctly coming up with a way to bring parents in the loop -- and it could have actually been a positive thing while also teaching the kids the old way too.... But of course they failed
That's what I'm trying to explain. You can't teach an entire class how to do something like that by just doing it verbally, so you have to come up with a way to show that same work on paper. That's the only way classes function and the teacher can actually check 20 to 30 students work....
I've talked to a bunch of math teachers about it and this is exactly the way they all explained it too.
It looks absolutely retarded when you write it out on paper, but the entire idea is that by the time you're done you can do it in your head without the paper
I can’t write grids in my head, and my kids don’t have the fine motor skills to legibly write out math problems in picture form.
Yeah, dude. I do “get it” because I’m not a friggin moron. But maybe it’s more important to teach kids the basics competently rather than aiming for a classroom full of 10-year-old John Nash’s. The former strategy will bear more fruit. I promise.
This is basically how I figured out how to do math in my head. Before common core was a thing. This isn't really the problem, the problem is all the word problems they've started introducing that all have a social justice slant.
t. GF who was a math teacher, their math dept refused to do the common core math program. None of those teachers are still teaching today. They also consistently had the highest test scores in their district.
That is exactly why I wasn't infuriated with common core the way a lot of other parents were, because it actually turned out that that's the way I've been doing math in my head my entire life... it's just the way that I figured out was easiest for me in school and as a cashier at 15 - 17 years old.
I've talked to many math teachers about it since then and they all said that I was correct about what the goal was with common core, but but they failed when coming up with a way to show it on paper and try to teach an entire class all at one time.
The goal isn't for you to be able to make those grids in your head or anything like that that, it's that once you have the understanding of numbers like that you won't need the grids or pen and paper.
They also failed because they were expecting several generations of parents at home to be able to still help with homework when they had no fucking idea what was going on..... That was actually the biggest failure is not coming up with a better way to bring the parents in the loop so they understand the purpose of this and how to do it themselves and help their children with it.
also most math teachers told me that it is quite difficult to completely grasp once you've spent your entire life learning the old way. People like us just got lucky that we had already figured it out in our head years ago.
Their biggest failure, aside from not consulting more actual experts that understood the goal, was that they decided to throw out the old way completely....
If they had actually consulted with people who genuinely knew how to do what they're trying to do in our heads, and could figure out a way to show that on paper in simplest form possible, while also teaching them the regular way to do math -- then this would be a completely different story.
It's like someone who understood how to actually do it came up with the idea and then a bunch of idiots who didn't understand it at all actually wrote the curriculum
I went to public school and was homeschooled. I loved being homeschooled EXPONENTIALLY more. We only did about 3-4 hours a day, but accomplished/learned soooo much more than the public school did in 8 hours.
Math teacher pede here. Master's in education and I'm certified to teach AP Calculus.
I teach the box method in high school. The bottom algorithm is good for one thing, the box is useful for a lot. It's called an area model.
It teaches students to break down multiplication into multiple parts. It also helps when you teach area of shapes. It helps if you scale the boxes! Then this goes into multiplying polynomials which helps in factoring polynomials.
It is extremely useful for a lot more than just multiplying numbers.
Try to do (x+13)(x-2) with the bottom method. You can't. You can with the box!
I remember before common core, my buddies wife, who was a school teacher, would teach the alternate methods to various students who seemed to understand things differently then the normal rote method. Most kids got the rote method, just a couple would get the alternate. Basically the alternate methods were tools she could use to help struggling students. I don't have kids but apparently they have to learn all the methods now. What a great use of time.
I starred at the top part of the picture for about 10 minutes thinking to myself, "What the hell is this shit?", before scrolling down to the bottom half of the picture and realized what they were trying to do.
Great job Pede, but don’t be too hasty with discrediting that new method. Because that “new method” is how your supposed to count naturally. If you had to count a pile of money you wouldn’t start with the change and then go to the ones. If you just do the first box your already in the ballpark for mental math. But if your balancing a checkbook all the digits matter so do it that good old fashioned way.
This is exactly right. This is also the reason why Barack Obama got such a huge fuck book deal.
Yup
Previously wrongthink
Holy crap I’m an adult and struggled to understand how the top equation was being solved or how to even read it. That’s insane.
I tried to help my freinds kid with "common core" and got the same experience. What the hell is this shit?!
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.
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
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
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.
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.

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.
After you use logic
312X20 = 6240
312X3 = 936
6240 + 936 = 7176
*1776

The top way is how I would do that math in my head. It is honestly more 6200+900=7100 and 40+30+6=76 and 7100+76=7176.
But 100% of the time if the math is actually important I would type it into excel or use matlab.
If this pisses you off wait till they have to draw boxes for fractions. Talk about a waste of time.

The first method looks like an interesting way to waste paper. Or am I missing something that the Green Party can find?
I am far more familiar with the second essential method. Mom used to do home schooling--you do your homework and show it or else.
What the fuck is that top shit
That's Common Core math.
We think Common Core math is bad? Common Core history is now being taught.
There is an overlap. Common Core history will teach our kids that 2+2=4 is racist.
They'll teach them that 2+2=5
Common Core math hurts to even look at. It looks like it was designed by a species that reads right to left.
Yep I showed my daughter this last year how to do math the proper way (bottom of pic) and she smiled, looked at me and said "Daddy knows a shortcut!"
Common core is utter crap. The only good thing to come out of this wuflu for me personally is my children will be home schooled.
Yeah, when my boys were being taught this I just said no and taught them the old way. Told their teacher they were going to do it the old way.
When did they change math? me RN:
What the fuck is with the boxes?
What the actual fuck is the top one? How can anyone do written math that way? Lol.
What the fuck is this shit. Uh, no.
I went to public school and was homeschooled. I loved being homeschooled EXPONENTIALLY more. We only did about 3-4 hours a day, but accomplished/learned soooo much more than the public school did in 8 hours.
Teach your kids what 74 x 24 is. It's the answer to a lot more than just a math problem!
Teachers' Unions are more interested in 64 x 31
Take my upvote you wonderful mathemagician you!
Turn something from three steps to six...
🌈 Easier! 🌈
Common core is the dumbest thing ever ever ever
I would hate to see how they do long division now.
They use calculator. Solving math problems in your head will amaze your friends.
This is so crazy they shouldn’t enforce any 1 way for math let the kids figure it out and use what they prefer

Try to do (x+13)(x-2) with the bottom method. You can't. You can with the box!
Um, no, I can’t...
It's easy. Draw a 2x2 box, like a punnet square.
On top, put x over one box, 13 over the other.
On the left side, put x on the top box, - 2 on the bottom box.
Then multiply each column and row, getting xx, x13, x*-2, and 13*-2. Which is x^2, 13x, -2x, - 26. Combine like terms, you get x^2+11x-26.
