THANK YOU! My son learned the technique but we want to understand WHY it works. This is beautiful. Great explanation - very thorough and easy to understand.
Thanks, you're explanation helped me realize that this is what my HS math teacher taught us as a shortcut, but they are just drawing lines instead of just doing the math individually and adding it up.
Best explanation I've ever seen. Now I actually understand why it works, I thought it was somewhat mystical or magical, yet I knew there had to be a concrete reason why stick multiplication works. By the way, at first 😆 I was thinking 🤔 wow I didn't know the Rated R Superstar teaches math, go Edge! 😅 You sounded just like him to me.
practical until you hit large numbers whose majority digits are 7-8-9's you have to assume the eye-hand and spatial coordination of the student is on point as they will make well and even spaced lines and "circling-lining the groups"...but still an awesome approach to learn...very visual :D
how do you represent zeros? for example 102 x 503, you draw a line, leave a gap, draw 2 more, then perpendicular draw 5, leave gap and draw 3 more, that would give us 664, because we basically just did 12 x 52. so what do we do with those zeros to get the right answer? would we leave 2 empty columns while counting up where it would be equal to zero except if the previous column adds up to more than 9?
nevermind figured it out, just imagine an invisible line for each zero, or draw it in another color, after that you just don't count the intersections with the invisible/ colored line. with this we should be able to multiply anything now.
Amazing to hear! Glad you found the video helpful and all the best as you gear up for teaching! You can learn more about problem based lessons here: makemathmoments.com/framework
@@KylePearceMathleteProbably because many of these videos put an emphasis on counting the intersections instead of multiplying the lines that intersect.
Lauren Robiadek you’d draw 9 lines with a big gap then 9 more parallel. Then, perpendicular to those two groups of 9 lines, draw the same thing. Count up your intersection points and you’re golden!
your playlist section needs A LOT of organization. it's very hard to look at, and i don't think you realize there are more built-in YT tools to further organize when someone views your playlist section on your channel.
Well I’m not advocating for us teaching this as I mentioned in the video... but if students understood the base 10 model, then it would make sense to try to build some generalizations like this stick method.

Actually it works the same way as an abacus. We Americans learned the hard way for some reason
So, after watching this, I’ve realized that school wasted 12 years of my life on “education”
So THIS is why it works. Makes much more sense now.
Sera Silva glad to hear it! Good luck!
Dude you need more views, this is beautiful
Don't we all?? :) A subscribe and a share would be appreciated! :)

Glad to hear that it made sense. Shortcuts are great, but when we don't know why they work, things get hard when we forget a step.
Absolut brilliant! Can't be done better.
Thanks 🎉
Your welcome! Thanks for stopping by!
The multiplication array examples is a good way to ease people to being introduced to it

This video is amazing, I am in college to be a middle school math teacher and I love this video

Exactly what I wanted to know!
10x10..? Basically you still need to know multiplication tables...no getting away from it...
Curious where you heard that we shouldn't become proficient with multiplication?

10:53 why this reminds me of the American box system
What about decimals?
I cannot believe you would try to suggest or say Canadians originated this method! Typical yt behavior.
Show how you do 99 x 99 please.

well done easy-peasy

pretty cool eh?
Here in united state it seems they don't give them time to learn multiplication
They don't. It's sad. They utilize the procedures but don't understand the principles behind them.

Great explanation! Thank you. In fact it is not a trick. Wich Maths is neuer.
Why don’t they teach this in America?
