How to do Lattice Multiplication

[@haley9503]

Everyone always says how teaching is done one way and how we need personalized methods...but the moment you show them another method they talk about how their way is easier and new stuff sucks. Which it doesn't. It's about providing a variety of methods so that children can find one that works for them. I do great with the "old" method, but I wish I had this one as a kid, simply because the "sliding down a mountain" thing makes it kind of fun! Plus regardless of what kids are taught, they'll try to figure out something that works for them (I did a lot of opposite methods, e.g. with finding percentages, instead of finding 20% of something I would find 80% and subtract to find the 20%). Anyway, this was awesome and a nice, simple explanation!

[@rachelteariki6999]

This method, had greatly help me leave my calculator at home. more so, numbers aren't a fan of mine. now, Im a bit more wider in the scope of numbers and a little confident. thanks to the help of those that freely give out their knowledge to me and others like myself

[@danielleharris4724]

Are you allow more time on your test, since it takes at least 3-5 min to set it up.

[@martinhammer7081]

I can't figure out why anyone would want to use any of the Common Core methods - they're all more time-consuming, more steps, and use more paper. What's the point?

[@carlossagastume4514]

I don't know who invented this method, it takes four times the amount of time to do it than the old method,why would I want to waste my time doing it this way.....but thanks for taking the time to explained this new method for multiplication.

[@MyTutoringBee]

First of all, thank you so much for watching and commenting. I do appreciate it. I get a ton of comments like this on my videos. I think it's interesting that so many people get hung up on the time that it takes over the fact that this is simply meant to help students who don't understand, or who process math differently and need a little bit more visual cues or scaffolding to help them achieve success. I completely agree that this method takes longer than the standard algorithm. But speed is not its goal, accuracy is. Sometimes students need this extra stepping stone to help them gain the self-confidence that they need. When students are forced to repetitively do something that they don't understand, that will only lead to frustration, and they will eventually shut down. If we have tools that can help get them going in the right direction, then let it take them a little longer. In the grand scheme of things, they will get there more quickly than if we just keep forcing them to do it one way.

THANK YOU!!!!!!!!!!!! helped me SOOOO MUCH ON HOMEWORK!!!!!!!!!!!!!!!!!!!!!!!!!

[@jseelig4330]

What I don't get with this is that you have to memorize what the multiplication tables are first in order to use this, so why add extra work just to make it more visually appealing? I understand the concept of using whatever way works for you, but it just seems a bit redundant to me to have to memorize the multiplication answers first and then to write it out this way. The same goes true with the common core methods. They are great for visually solving the problem, but in the end, you still have to memorize the calculations.

[@amirabdelli2295]

Initially I was on the same page. Seemed like a longer, yet less rigid, way to get to the right answer. Then I saw the beauty in it. It allows kids to work through the problem in whatever direction and order they please. Whereas with classic multiplication there is a rigid syntax that’s required. Just my $0.02.

[@natachalabadie155]

I love your channel I wish u were my teacher

[@hotforteacher7540]

So what if I place the 4 over the zero instead of zero over 4? what are the rules of this process? If I don't know the rules I will never figure this out. The original way the rules are simple.

YES

[@AlexanderScott66]

As a tutor, I tell everyone that needs help with this kind of stuff to just forget it and do it the normal way. They understand it immediately and solve the problem much faster than they ever would with the lattice method. That method is just so time consuming and you get distracted easily by all the artsiness. Schools should honestly stop teaching it because this way is just more complicated than it needs to be.

[@MyTutoringBee]

That's really great news for your students! I tutor a lot of kids who really struggle with the standard algorithm (the "normal" way) and they find this method really helps them. We eventually get back around to using the standard algorithm, but this has been a great bridge for them to begin to feel comfortable with multiplying multiple-digit numbers!

[@yourboypaged2020]

I thank you lady You’ve helped me alot

[@MyTutoringBee]

[@hernje]

Initially, I was so happy to here the voice of a female teacher. That feeling quickly dissipated once hearing this dizzying method of multiplication. It’s clear, men and women’s minds work differently.

[@voodewmoondragon]

What was wrong with the first method? Faster, easier, less BS to understand

[@MyTutoringBee]

That's the beauty of it; nothing is wrong with the first method! There are just so many ways. Pick the best one for you! :)

[@johnramocan543]

VooDew MoonDragon exactly i fully agree

[@TheBrycat]

I see all kinds of problems with the first method. I've tried teaching it to a couple of my non-mathematical kids and they cannot get the right answers when you get up to 3 and 4 digit multiplication. There are simply too many places to go wrong. They forget to add in the number that they carried over from the multiplication or their columns get too messy. And when they make a mistake, it is very hard to pinpoint exactly where the problem went awry. With this method, you reduce the problem down to a bunch of single, independent multiplication transactions. Then you do all the addition separately. Everything has it's place. My kids can do large digit multiplication problems accurately with this method whereas they cannot with the first method. I doubt that this method will work for all kids, but it works beautifully for mine. Far better than the traditional method.

[@janedar9701]

I teach High School Math and some students can't remember the algorithm or "old fashioned" way. But they understand this method.

[@Jayson1940D14]

I dont want to get into a debate on education principles on your how to video, but increasing the methods of solving math problems only increasing the workload of our educators exponentially at a time when they're already the lowest paid and least respected.

[@swishsquish9726]

My teacher taught me this and I really find this helpful cause I never understood her

[@Luv4duckies]

same me too

[@dennisodell4923]

Kids learn in different ways. Some learn visually. Some tactile. Some verbal. This is just another way to do multiplication. The more ways you can show how to work a problem the more kids you bring on board. As a teacher, I wouldn't show this on a daily basis, but it does help them bridge connections and it's fun to boot.

[@MyTutoringBee]

Thanks for that input! I agree! This is, by no means, the only method I teach the students I tutor. But it does come in handy when they are just so frustrated and overwhelmed with the standard algorithm! It's like a breath of fresh air for them that they don't have to keep trying at something they don't yet feel comfortable with.

[@anonymousone3998]

As a non visual learner (I'm kinesthetic) I would have zoned out after the third step as a student. I get it now that I'm an adult, but it's still more difficult to grasp because I naturally think, "What connection to the big picture does this have?" and it's not clear. (To me.) But it's definitely helpful to some. :-)

[@MyTutoringBee]

I agree! This isn't my favorite method, but some of my students just LOVE it! I prefer the Box Method (Partial Products) out of all of the "alternative methods" of multiplication!

[@vaisata]

How young are the kids learning this? I'm was very good at math and this is just plain confusing. Turing one of the simplest of actions - multiplication - into a multi stage process with helper drawings, just blows my mind.

[@MyTutoringBee]

I agree that this method takes a bit of set-up and space on the paper! However, some of my students find this method so much more manageable over the standard algorithm. You are very luck to be good at math and find multiplication simple! Not everyone feels that way about math, so I really like to be able to show them different methods and find one that works for them so that they can enjoy math more!

[@vaisata]

@@MyTutoringBee Certainly it's good for students to understand and be able to do multiplication. But I hope they don't come to rely only on this method as it takes very long, especially for something so foundational. But as a stepping stone, it sure might be helpful for some!

[@ghoulishtheories7979]

@vaisata - It may seem long because there’s a lot of extra steps in the video that are out there to try to make it easier to understand how to go about it. I never personally used the dots/X’s, and you just simply count out the digits in each number, and translate that into columns/rows. (Although I would always put the larger digit number at the top, as it just makes it look a bit neater, and less jumbled in my opinion. But where this method shines, is when multiplying large numbers, or numbers with decimals. For example, say we used the numbers in the video, and turned 47 into “4.7”, and 15 into “1.5” - You would put the decimal point still in between the numbers, but above the line (in the case of 4.7), or to the right of the line (in the case of 1.5). The lines that divide the columns/rows. Then you take both decimals to where they run into each other, then let them ride down the chute at that point. And you have your decimal place figured out before you even have the numbers put in. (Or you could do it after), it’s really up to the user, which also helps make it more personalized.

[@sweet158]

I like that there are more than 1 way to figure out the total. If children use this method, wont they have a harder time in adulthood to calculate?

[@MyTutoringBee]

Like a lot of the methods that I teach with these videos, these methods are not designed to be the ONLY method students learn how to use. This is a great method to help students who are really struggling to understand the standard algorithm (the method I quickly used on the left), but I eventually teach my students that method as well. The Lattice Method is sometimes a great bridge between the two methods for students who are struggling.

Very good video really helped me out

[@MyTutoringBee]

Glad it helped!

[@user-fk4tc9nf9w]

Please please please, could anyone let me know what is the theory to do the math in this way? Thank you!

[@MyTutoringBee]

It just provides a different way for students to re-group place values. With the standard method, we are basically multiplying the ones place of the lower number by each place value in the top number. Then we move on to multiply the tens place of the lower number by each place value in the top number. We then stack those multiples underneath and add the values together. With the lattice method, we are regrouping in a slightly different order and eliminating the need to add up all of the multiples at the end. In this video it does take a while for me to complete the problem, but that is because I am taking my time to explain how to do it. I've seen students use this method much faster (although the standard algorithm is ultimately the fastest method) once they get the hang of it. This method usually works as a great "bridge" for students to get comfortable with the idea of multiplication with multi-digit numbers and they learn the standard algorithm later on as well.

[@FM-Patriot]

We home school our daughter and I teach her math, and this is one of the main reasons why. I am not trying to be rude or aggressive in any way, but why would anyone choose to teach a child this method? I can't imagine a situation in the "real world" where an adult would ever use this method. What is your opinion in this matter? Thanks

[@MyTutoringBee]

I understand where you're coming from. Honestly, I really don't like this method either. It gets too jumbled up for me. That being said, I have taught this (along with other methods) to my students and some of them pick this one as the "easiest" for them. It's all about giving students options and letting them pick which one works best for them. And let's face it, adults in the "real world" use calculators - myself included! :) Thanks for your comment!

[@snazzyengineering]

...except when they have to augment a nine-by-nine matrix on a Linear Algebra final. No calculators there! There's simply no chance that they'd be able to perform this method fast enough to compete with other students. Giving them a choice, and showing them different methods of doing things is great, but eventually they're going to have to either use a distributive model to do hand calculations, or better yet, they'll have to develop really, really good mental math strategies to be successful in the long run. And then, once they pass their classes, they'll just use a calculator anyway, and those mental math strategies will be forgotten...

[@TheBrycat]

I homeschool my 5 kids and I just learned this method and I think that it is brilliant. Having spent several months on a single 1-week lesson of multi-digit multiplication (the American way) with my oldest child, and having graded countless pages where the poor child couldn't get a single question right, I think this is much simpler. It looks more complicated at first, but we forget how hard our method is at first as well. This method eliminates all those pesky carry overs that get put in the wrong place and the merging columns that kids with poor penmanship can't keep straight. Every digit has its proper place. And you only ever have to know your simple times tables and single digit addition. It really is much simpler when you get to large numbers. Just for fun, I multiplied 948,623 by 835,741 and in just a few minutes, I got the correct number, 792,803,134,643. I never, ever, ever could have done that using the American method of multiplication. My calculator couldn't even provide me with the full answer in order for me to check it. I had to find a high-powered multi-digit calculator online in order to see if I got it right. And I did. And, for me, it was fun. This method reminds me of doing a Sudoku puzzle. It may not be every person's cup of tea, but for a lot of people, this method is easier and more accurate.

[@janedar9701]

I teach high school math and some students have a difficult time remember the steps for the older method. Some prefer the lattice method or this one.

[@ericaselby9817]

MyTutoringBee that is very true. The only time I do not use a calculator is for basic math. My son is a very visual learner, so he may like this method better. Right now I just use basic shapes and have him count those to solve his problems.

[@MyTutoringBee]

Thanks so much for watching and for your comment! Yes! That is exactly it! Just like this method seems confusing to you, the standard algorithm seems confusing to some of my students. That's the beauty of having alternative methods - some people just learn in different ways. I've sat with students who are in tears trying to learn and understand the standard algorithm thinking and saying things like "I'm so stupid" and "I hate math". Then I show them some alternative methods and the light blub flickers on for them. It's an amazing transformation in their attitude which then transforms their work! They suddenly have a tool that works for them and helps them to build their confidence in themselves! Thanks!

That's so interesting that you used this method for so long! I'm always encouraging my students to use the method that they are most comfortable with and have the most success with!

[@cagedraptor]

just may be that I'm getting old but I learned the first way, it works why confuse, change and alter something that works. Seems, because I'm getting older I think, that people change things just to be changing them. If it isn't broke don't fix it. Just maybe its me but that seems to be a heck of a lot more complicated, plus could get really lost. Again, maybe if you were originally taught that way it would seem ok. The carrying the 1 could really get confusing, I think. Over all I see how it works but it really seems more complicated and longer than the original way. Again, seems like today's society wants to change everything and make it more complicated than it needs to be.

[@MyTutoringBee]

I totally hear what you're saying. The standard algorithm is definitely faster and more direct. However, this method was certainly not just created to make things more complicated. I work with students one-on-one and I see first-hand how frustrating the standard algorithm can be for some learners. This method really works well for many of my students, and it's something they can do independently and feel accomplished at a skill that they would otherwise fail at over and over again. They do eventually learn the standard algorithm, as it is much more efficient, but methods like this can be a great bridge for those who need the extra support!

True, you would need a lot of boxes for that problem, and it would take a while.

Beth, I know you are a smart person but a conventional person could leave you in the dust with the old school methods.

[@MyTutoringBee]

Thanks! I appreciate the sentiment, but "smart" and "fast" are two mutually exclusive terms. And I'm not sure what you mean by "conventional person." This method is not meant to be fast. I agree that the standard algorithm is usually the quickest way. However, this method provides a visual structure and scaffolding to students who really struggle with the standard algorithm. I've worked with thousands of students over the years, and not everyone thinks the same or processes information in exactly the same way. When a student comes to me in literal tears every time they even LOOK at a multi-digit multiplication problem, forcing them to do it with "old school methods" just isn't going to cut it. Why not give them a method that works for them? Eventually, they can learn the standard algorithm, but this method can be a significant stepping stone to help them get there.

She did every problem the way you are showing it. But some how she kept coming up with the wrong answer. This girl needs some confidence. She gets so frustrated and discouraged. I try just drilling the multiplication table into her. But she freaks out and whines. Making it impossible to teach her. I honestly don't understand the taking 20 steps to find the answer to a simple question. Her 5yr old brother can add quicker than she can. You hold up 5 fingers on one hand and 3 on another and he yells out the answer. You do the same to her and she has to count from 1 and up. She can't just go 5,6,7,8! Or even just 8! Like her brother does. Her teacher tell my sister that my niece needs to work on her math facts. I am like okay isn't that the teachers job..TO TEACH HER? It's getting old fast.

The old method you were done in less than a minute, and the box way it took you over 4 minutes to explain....why would anyone want to use the box method ?

Thanks so much for your comment! This video gets that question a lot. With the standard algorithm, I didn't take a lot of time to explain that one, because it's the method a lot of people know how to do already. With the lattice method, it's new, so I slowed way down to make sure to explain all the steps. However, you're right that this method just generally takes longer to do - but for some of the students I work with, sacrificing a little time is worth it for them to get a more accurate answer. The standard algorithm can be frustrating to some students. They'll forget to multiply diagonally, regrouping numbers can get messy and lost, and the constant switching back and forth between multiplication facts and addition facts is too much. I like to teach multiple methods and let students decide which they like best!
