That’s pretty amazing. I wish we would have learned math this way when I was a kid, I know I would’ve picked up math more intuitively.

This is the stupidest way of doing multiplication. I hope Common Core stays in America.

3. Paul Colombo says:

This is how an idiot would teach multiplication to a moron.

4. Mike Rushing says:

…and that just added two extra steps to the math problem.

5. Eff Gaaglé says:

I gotta say, even though I already basically understood what the long multiplication was doing, and basically do the same thing whenever I do mental multiplication, seeing it laid out like this gives me renewed respect for it. It’s really an ingenious little algorithm for quickly computing a product by hand.

6. Captain Groovy says:

The graph paper explanation is a good tool to understand what a number represents as far as One’s, Ten’s, Hundred’s, etc however, this should of already been taught when teach basic Addition and Subtraction.  Once again educators are trying to put the cart before the horse.

16 x 27

Learn the multiplication and division tables and don’t worry.

8. Martin Dronesclub says:

this is making things way more complicated than they need to be. 16 x 30 you can do in your head. minus 16 x 3 and you get the answer.
areas of sections. math doesnt need a backstory?

Anyone make a “multiplication with the area model” t-shirt? I think the visual of connecting this to the standard algorithm is super compelling, especially with color coding for each of the partial products. I’d be stoked to wear that on my back!

We just released a music video which teaches you the area model through a song about a farmer planting green beans and black beans! It’s a great supplement to the excellent visual instruction you’re watching by Khan Academy.

Thanks needed it for school😀😀😀😀😀

This video was so helpful. I had to learn this to help my daughter with her homework. Other videos did not help, we kept getting wrong answers….we got 8/8!!! Thank you!

Thank you I need this for school I am learning it.
