Just wondering how I was taught and this is what's going to cause problems with kids. They're going to be taught one way when their parents are taught something else

This didnt age well

So funny that MOST of the commentors are missing the key points altogether. So much for problem solving and thinking outside the box. People learn and solve problems in different ways

OK, if this method is better, then why are kids doing so much worse in school then they were decades ago? And why is it people who are promoting CC claim that the old methods are bad, as in claiming that it's bad to just learn methods and algorithms is bad, yet when explaining the new way they reduce it to learning methods and algorithms.

I understand now. I would have received better grades if I was taught this method back when I was in school.

China became better at counting and calculating than everyone's else thanks to the cultural revolution : they invoked the spirit of Mao Zedong first by quoting sentences of him from the little red book. Trump needs to publish a little red book of his tweets.

AI will only make this more fun

Common core is another way of doing the same thing. Math doesn’t change. I at 54 learned everything this guy showed just in a different way. Math cards, grids and repetition and it all ends up in the same place. Math is already hard for many kids and making the path to the same destination more cumbersome and complicated does not help.

Old video, your approach is good but no need to criticize old method. Different people have different mental models.

Getting the right answers with the old tried and true methods as kwikley as possible will find the best burn rates for solid or liquid fueled rockets. Long and drawn out common core math is way too costly.

Having grown up with "old math" aka *MATH* , I had to help my little sister with common core homework and I gotta say, that shit is HOT, WET GARBAGE. So many extra steps and useless crap. I also taught her old math along side the CC math and she said "yeah, I wish they'd just teach us old math, it's easier"..... 🙄😒

My sister hired an old school retired math professor to teach her daughter math using a slide rule and show how she got the answer every time without a calculator or a tablet just hand written. Basically to show her work and understand how she got the answer.

But...and it's a HUGE BUT!!!...you NEVER get to the shortcut after you teach the principle. How do you teach division?

CCM doesn’t work! I can say that watching kids struggle.

The problem with CCM multiplication does not tell you what multiplicatipn actually IS any more than traditional primary school maths does. This can be seen easily when you transition from positive natural numbers to integers, not to soeak of rationals or reals! Multiplication is far more than repeated addition. It is about PROPORTION! When this is understood, the different algorithms employed to get results can be seen as tools! You do not need a deeper understanding of physics when using a hammer on a nail - just how to bang it. This would correspond to the algorithm. What you really need to understand, is that you are trying to permanently join two pieces of wood. The joining itself would correspond to the multiplication! Understanding the inner workings of hammering in a nail as compared to the effect of a screwdriver and why they both may be used to join two pieces of wood is a topic for later! Particularly when the subject at hand is carpentry and joining.

Common Core Math isn't math test, it's obedience test.

You explained with using MEMORIZED MULTIPLICATION. THAT IS WHAT SHOULD BE FIRST....

That mother phucker is 20 off math doesn't change I been doing gen x Math I was taught right and quick everytime

Math isn't that hard for most people like this fool stated. Most people go to work, receive a paycheck and pay their bills. All the while balancing their checkbooks.

With a declining education standard our nation has been going through for decades, why not just go back to what worked, instead of always trying to reinvent the wheel?

That's just STUPID ... and you can't fix that.

The second method is actually fewer steps… you have more written but, you don’t have to backtrack and scribble things out. It’s also cleaner math. It’s really the same thing, it just takes up a little more paper. Also I hate seeing crap scribbled out on my paper.

How does the student know that 4 x 40 is 160 unless they have memorized the multiplication tables and does 4x0 is 0 and 4x4 is 16 in their head? I don't remember exactly how my teachers taught me but I have always known I was multiply 4 times 40, and that is why you put the 0 in the ones column.

Wrong in so many ways.

What retard came up with this method. You trying to teach kids math theory in 2nd grade. Probably confusing them more. This is simple math why complicated it?

This is the biggest load of crap ever. If common core is so good, then why are kids struggling in math?

This is a bunch of gahoohy.

Um, I am 73 yrs old. I got straight As in math in school and learned advanced statistics in graduate school. The old ways have served me well and I always knew what the methods meant. The old ways work more efficiently.

So basically saying that kids are too ignorant to do it the way that’s been done for hundreds of years. Changing how it’s done won’t make kids like math more. And there’s videos on here showing kids being scolded for getting the right answer doing it the “old” way. If the answer is correct it’s correct! It shouldn’t matter what way they get it if your going to eventually tell them there’s a “shortcut”. With all the other garbage we have to worry about in schools these days now we have to worry a kid will fail a test with CORRECT answers because they don’t “spell it out” the new way.

I've been looking for content to actually understand the common core stuff. I've gotten nothing but vagaries this far. But I've only heard two arguments against the older model, and it's what you presented here. The most lack luster and pathetic "oh, you're not allowed to write 20 here for some reason." "Oh, you just have to remember to add in the two later." You're attempting to (badly) make simple things sound egregious. When they're not. "We just told to do this, we don't understand why." Because you're not teaching it, you're attempting to insult it. Why can't people just be honest about this stuff? Edit: Condescending. You're being condescending. What you've shown I have not seen in my son's math book. What was presented here was merely a different way of doing the same thing. This is not at all related to any of the common core stuff I've seen before.

I thought CC was supposed to help people better understand mathematics? It seems the results are worse than how we used to teach. CC attempted to fix something that wasn’t broke, and ended up breaking it.

Use a marker that doesn’t show up is a bad idea 👎

There is a deeper psychological of children. Simply teaching them how to think when their young mind isn't yet adjusted to being an independent thinker causes confusion and conflict. Up until their teen years, children are predisposed to do as they're told, not by the method of rearing but rather natural instincts. They have yet the necessary experience and self-confidence to make independent decision. Teaching the traditional method is much better for them. When they can branch out, CC is more appropriate, assuming they haven't already been tainted in their youth by CC. Also, unfortunately, each child's transition from dependent thinking to independent thinking varies in age and duration of transition, so yeah, there's that.

This is not important enough to alter what was taught before.

If this is what heppened to you, you simply had a horrible math teacher. It doesn't mean modern kids have to suffer.

first one is the easiest.

We were not taught "rote" algorithms nor to get the answer as fast as we could. We learned place value. We drew diagrams and were expected to internalize these concepts. We were not expected to write out all our thinking and work on each and every problem but we were expected to understand how math works and then to represent that in an efficient, understandable form on paper. I am 75 years old and was never in a class that didn't teach me to understand the way math worked. We did memorize math facts in order to work more efficiently, but we were always taught why those facts were true and were given the tools to work out problems we had not encountered before. I am insulted by the verbal superiority implied in this video.

I definitely see the advantage of learning multiplication in this new way. Especially as a person progresses into deeper math. But, some kids are just mentally gifted and have a common sense understanding of math. I would probably want to separate the gifted kids and progress them faster than the other kids.

This is so much easier!

this research about what works was done on poor students. most students don't need these tools and learn the concepts easily.

I'm sorry I have to share a planet with people who aren't infuriated by this jackass. "We don't tell the kids why blah blah blah..." So tell the kids why you blithering dripshit. You don't have to switch to common core; you could just switch to telling the kids why. And here's an idea that might just be crazy enough to work. If you tell somebody how to do something and they don't understand maybe you could try explaining it in a different way or try adding some details that you left out the first time. Your inability to teach 4th grade math is a reason to slap your mom's face for having such a dumb shit, not for changing how math is taught all over the country.

Because they want to confuse and dumb down students. Common Core confuses EVERYONE. It’s stupid and so is anyone that supports it.

This is for the ret@rds who just can't learn math the normal way. We have been doing it the old way since the beginning of time with zero issues, but now the kids can't figure it out? Parents need to get back to parenting, get involved in their kids lives and stop letting the schools raise their future social justice warriors.

First off, this is not math, it’s arithmetic !

People have different learning styles and by showing how to do this 3 different ways (in reverse order) then allow them to use which they prefer. The answer is core

If kids are not memorizing multiplication tables, it doesn't matter which method you teach, they still won't be able to solve this math problem. It's all well & good understanding common core methods, but without having the basic foundation (adding, multiplying, etc. in their heads), these methods seem more cumbersome & confusing. And if they knew "traditional algorithms" or "old math," then you don't even need common core!

3:55 "later we can teach them the shortcut so they can save a tiny piece of paper..." 1) it's not a an insignificant amount of paper, because what possible justification can you explain to use more words, or numbers, to communicate, and process, than is necessary ? Why write more than is needed ? 2) it saves TIME. What is the point of wasting time writing out the entire process when you already know the shortcuts to get to the correct answer sooner ? 3) it saves EFFORT. mental processing, and attention, are not infinite, so if you want burn out kids trying to do math, then common core nonsense like this is how you achieve that. Just ask anyone with autism and/or ADHD about "executive function units".

If you understand the concept of units ,tens, hundreds etc the first method is perfectly easy to understand plus it’s more concise and logical..maths is a difficult subject you are making it more complicated..I noticed that when you came to add up the rows you did it in the traditional method ..in fact you did it in your head ! ..

Most efficient way to turn one multiplication problem into 4 multiplication problems 😂

My teachers had issues with me when I came to maths as I did it differently to how they taught it and I was marked down wrong even though my answers were correct and when I explained the way I went to get the answer because it was different to how they taught it they didn’t except my findings, I hope with this way of teaching you let the child know that if they find it in a different way than what you are teaching as long as they get the answers correct there is no wrong way, cause they might be wired differently
