What was the old way of teaching? I am 28, and that video exactly explains how I was taught math my whole life.

That was me.

My concern is that these new processes are laborious, and the curriculum still covers the same amount of topics. We are losing kids this way. Every day a new concept that takes forever to complete.
Hopefully, once everybody is comfortable with the curriculum, there will be a little more liberty in taking shortcuts. To me, as long as you get the right answer, who cares how you got it? I know that some teachers/schools don't agree with that, but if you can do some math in your head, or use some shortcuts for fewer steps, then more power to you.

the way on the left in the video. carrying the numbers on top of the multiplication problem

this is the wrong way to look at it, and why i'm glad my math was graded on the steps and not the ultimate answer (which was a single step)
understanding what you're doing is important, especially if you're going to move on to the next subject
this is like when i did freshman testing with my engineering group and i was the only one who passed trig, b/c i didn't use a calculator. the rest of my group (hopeful engineers, mind you) had no idea how i did it without a calculator. if they had a calculator, they could easily get the right answer, but if they only had an undesrtanding of the concepts at that level, they could not move on to the next subject.

Basically 2x the work, Still the same time frame.
Take the example given.
The kids still need to learn multiplying two digit numbers in one day (I realize it's not one day but as an example).
Instead of teaching the old method, they now have to teach 3 different things. Box, place holders, new multiplication. Students need to grasp 3 issues now. Tomorrow teacher still moves on. And common core math is more progressive, so there are more topics added. Still go to school the same amt of time. Increases homework, parents can't help....
Idk. I think starting kids off early will help with these issues but the sad thing is that middle school kids are being thrown into this and getting lost.

Sure. I get the understanding part. But there are kids, maybe top 15%? Who execute and understand the math. I have never seen a teacher teach math and not verbally explain what is going on.

If you honestly believe your kid is a top tier student, then it is your obligation as a parent to find advanced education for your child.
We don't need to blitzkrieg all the children in a standard classroom for the 1 or 2 that may well beyond the skill levels of the rest of the class. That 1 or 2 need to find ways to progress outside of staying in a standard classroom. There are plenty of opportunities for them.

54 is just a symbol of a bunch of different things. (50+4) = 54. kids see that as a math problem with 3 individual units, when they should understand that you're saying it's just 2 ways to represent the same thing
Haven't watched the video, but this is pretty much the way I taught math for my 11 year career. I rejected all the FOIL bullshite in teaching binomial multiplication and just related polynomial multiplication to the way they were taught to multiply multi-digit numbers.
I just hated all the rote memorization acronyms the students came to my class relying on. I was much more interested in teaching the nuts and bolts of what was really happening with the math fundamentals.

I'm not saying that 
I'm just saying that this is an extreme breakdown that I wonder how many kids actually need.
Time span is so important in math bc it is so progressive. Any tweeks need to be carefully considered.
I just wonder if it's beneficial to
Baby kids along while others sit in boredom and then move everybody along the next day no matter what.
I really do hope it works, there are just so many variables.

Kids are starting younger to get the concepts down, you say 2x the work but a student who is taught it this way has it down pat and understands the concepts earlier. Therefore, those students are able to do it quicker than someone doing it the traditional way and a teacher can move at the same pace.
Students are just learning the concepts struggle with the work and pace because they are having to think of this in a different manner, same with parents who were taught the traditional way.
At some point all schools need to quit spoon feeding kids and start challenging kids and you may lose some but overall you will better students in the long run.

Ah, I see. We used the right side some as well but definitely worked with the first part more.

there is definitely an issue with overhauling any system overnight. there is going to be a lot of drag and inefficiency
but over time, this will decrease and the new generation taught in this method will be running full steam ahead
it's kind of like switching from english standard to metric in the 70s. it was rough at first and we rejected it, which has hurt us in the long run. we have to get over this hump for the results down the road
we're not good at seeing the big picture in the west. it's just a cultural trait

I like this new way of teaching. Honestly, I heard about how schools were teaching kids a new way of math, but I didn't really understand what that meant. I'm curious to see how it'll make a difference. Math is basically a different language, and I'm glad that they are teaching the actual fundamentals as opposed to deriving a number.

This isn't the first time a 'new math' sham has been pulled. In the 60's some Yale Mathematician rewrote the Algebra texts to be more abstract, and therefore *better*. Everyone who learned the old way was worried their Algebra skills were obsolete. Everyone who learned the new way felt they were on the cutting edge. There really isn't anything new here. If anything, they are introducing skills found in Algebra to teach basic math.
Remember FOIL? (First, Outer, Inner, Last)
45X24 = (40+5)X(20+4) = 40x20 + 40X4 + 5X20 + 5x4

Having to help my kids with algebra homework may be the reason I don't have kids.

I wish Louisiana educational system would undergo a radical change. That the teaching would start to challenge the students more.... right now some schools what they teach/test doesn't properly prepare all students for PARCC or LEAP

My daughter came home with some of this hippy division the other day. I then taught her how to do long division in about 2 minutes.

I'm really good at simple math, but that was an awesome video. This is how they should be teaching kids.

People who are good at mental math have always used this method. The 4 box way of thinking is ok but if you can get good at mental math involving numbers below 100 you can use a 2 box method. I know it isn't difficult at all but for instance.
In the problem he did. Just simply do 45 times 2 and add a 0 to the end giving you 900. Then add 45x4. If you can't do things like that quickly you can think of it a couple different ways. 50 times 4 is 200 and since 45 is 5 less than 50 it will be 20 less than 200.
Or.
45 times 2 is ninety then just double that.
It's all about seeing the big picture.
