Why Common Core math problems look so weird

There isnt one right way but there is a BEST and QUICKEST way. Common core is inefficient.

Add a column of 10 figures in the hundreds of thousands try that in common core. It will take you all day.

I don't see much use for this method other than explaining subtraction on the base level. Such as why it is that 11 - 8 = 3. (when the larger digit is on the bottom). A young student may not readily understand that 8 + 3 is 11 so that correlates to subtraction when you take 8 from 11 to get 3. If the larger digit is on top then this method has no practical use. 9 - 7 is obvious that 7 is 2 away from 9 if the student is able to count to 10 properly.

A $hitty explanation?

I'm a vehicle tests engineer that tests vehicles that sometimes only have kilometers per hour for speed. I do not have the direct conversion memorized because I find division and multiplication of decimals to be overly complicated and unnecessary to memorize. Instead I remember 25 mph is 40 kph and 50 mph is 80 kph and that every 5 mph that change is an 8 kph change and add and subtract 8 or 5 the appropriate number of times from the closest memorized value. And that sounds way more complicated spelled out but means I'm not memorizing multiplication tables of 1.6 or 0.62

Common core makes sense. I never learned common core but that's apparently how I do math naturally - in chunks based on a limited number of memorized values using a proper understanding of what I'm trying to do. And I've done math up through partial differential equations and have managed to guess techniques from equations for more basic math before being taught in the past.

Who said that the classic method doesn't give you understanding how it works?! This all was explained, and a short cut shown

My mom taught me how do mental math when I was in elementary school and my teachers HATED it. I can solve large problems quickly in my head in seconds but since I wouldn’t do their far slower and clunkier method and show my work (I came to utterly hate those three words) I flunked many math tests and found homework beyond useless. Help kids find the method that works best for them and forget trying to rigidly enforce a standard.

I think I would have done well with common core math because I had a lot of issues understanding traditional arithmetic.

Meth in some way is like baking....

I think that there are some aspects of common core that are useful, but I still prefer old math

Is common core really this big of a problem? I studied in Hungary and we originally we didn't learn this when I was in like 3rd or 4th grade but once I needed to help my younger brother, and after seeing what he wrote down on his paper, these half done switched up formulas, I needed like 15 minutes to figure out how adding together and subtracting works, multiplication was even easier. I think it's an interesting way to calculate, but I personally doesn't find it much better then just calculating in head

Why common core is satanic and evil*

There fixed the title

The efff

I am good at math, always was. All these methods make sense. Teach all ways to get a population that can explain it to everyone

the underlying logic of the old methods of math are obvious if you just think about it

I'm wondering when people were taught that numbers were anything other than numbers. Every segment that I've watched says the same thing about how "inflexible" people of my generation are when it comes to thinking of numbers. I was always taught that a number is a number combined with other numbers to make another number...thus flexible. That you could get to the answer in a number of ways. However, it's only when it comes time to "show your work" that students get punished. Some of us work differntly. Some of us can do it in our heads but we were punished for GETTING THE ANSWER RIGHT because we didn't "show the work". Who's problem is that? NOT the student's. Why punish them for getting it right? That needs to change.

Why do people keep saying "it doesn't show you what you're doing" while showing you what you're doing?

Here's a question: IF this "works", then WHY are we still not making "progress" in our math and science standing on the world stage? Right...because schools want you to do it their way instead of the way that works for each student. Teach the different ways to get the answers then let the student decide which method works for them. That way each student uses the method that they like and all the teacher needs to do is look at the answer! WHY punish students who can do the math in their heads? WHY punish students for using the "old method"? THAT'S why kids don't like math. They're being punished for getting the answer right in their own way!

Bill Gates dumbing down the children so they don’t question when they try their depopulation again when they are older.

common core math is needlessly complicated and useless

Good to explain, but after that the method shall be the conventional.

I feel dumber watching this

I love this!!! This is what I already do in my head!!

what do you mean carrying over doesn't explain what you're doing?
and doing it that way is makes it look way flexible even fluid than common core in my opinion

Taught nothing, learned nothing, no answer to why, bad video

How do they expect to teach kids limits and logarithms?
What about integrals and derivatives?

At the end of all the number jumping, you're still doing traditional math. It's masturbatory and pedantic.

This math just overcomplicates things to new level. Does not make any sense at all. I can see kids learning this in a more easier fun way.

I was in the middle of the shift between common core from old math. So i have a sort of mix between memorization and common core steps when i solve equations, i have the entire times table memorized though when it comes to addition/subtraction i use common core methods to solve those equations. I feel as though a mixture of both is good.

The phrase uttered here that “there is no one standard way to get to the solution” is…wrong. The solution is the Ockham Razor solution … ie the answer arrived at in the most elegant parsimonious manner. Think of it this way: if you are in the US military in artillery, and you are in the midst of combat, you’re not going to reposition your artillery using common core math. Instead, you will use “old math” because that yields the solution in the quickest, most elegant manner in a moment when every second counts.

I don't understand. The US ranks 27th in the world and instead of copying what the superior countries do, you invent a new and cumbersome way to do math? It is a fun method though, but I don't think it would have aided my understanding. Maybe it could help those kids that rote learned multiplication tables, but did not really understand what was going on. You know, the kids that can tell you in a heart beat what 8 times 7 is, but is dumfounded by, and hopelessly struggle to give the answer to 10 times 11.

Doing subtraction and multiplication is already this unnecessarily complicate. Try fraction, root, negative numbers and algebra.

Complete waste

So, USA have started using common core math but the metric system is still to scary to learn!?

It just seems senseless and pointless

Hmm… well to be fair, I can do vector calculus, but I really don’t know why long division actually works. (Would be interesting to learn the real math behind it as an adult). Retro multiplication was just using the distributive law… makes sense algibraically.

So... Seven years on........ using this new method. has the position of the USA in mathematics improved?

There is only one way to do math and common core isn't it.

This seems so unnecessary..

I would have hated this at school. Absolute waste of my time

So we Stop teaching Subtraction and now only teach Addition. 🤔

Why? Do the children not understand that them number symbols aren't just funky drawings and are actually values of measurement?

The traditional method is much easier and faster. Common core has too many steps and ain’t nobody got time for that.

But it takes too long…！

The goal of Common core is laudable, but it doesn't often work in practice. There is already a very old way to teach maths to children that clearly shows how numbers work, and they're called Cuisenaire Rods. They were invented in the 1950s and they are much better than common core methods because they are immediately intuitive to parents, children and teachers.

It's hilarious how to do 325-38 she does all the steps, but then she adds together the four resulting numbers using the 'old' method. Anyways, it's sad to see young people on construction sites trying to do math like this. Most get fired pretty quick. Every year since Common Core was introduced, US math test scores have dropped.

You know what's funny, is that I never learned to use common core and somehow that's how I do math in my head. Interesting.

It's confusing

The thing a lot of people don't realize is that this type of thinking can be applied to other base counting like binary and hexadecimal that makes a lot more sense than only knowing numbers the old way. Important as we are more and more in the technological age.

And we wonder why we have a teacher shortage.
