Methods of Multiplication for the Mind

I remember learning multiplication in 3rd and 4th grade and having to do those dreaded time tables! Then, after time tables. we had to move on to two digit number multiplication! I remember only learning one way to do multiplication tables and that was the old fashioned long way of multiplying. Like you just saw in the video, this is the method I believe most of us learned, but I'm going to talk about other ways to multiply double digit numbers!

Here is a problem solved in the standard way:

Now there are many ways to solve this and not use the standard method! 

First there is a method called the Lattice Method of Multiplication. After learning more about this method, I realized that this is a very easy method to catch on to and teach! Learn how to do it in this short video! The Lattice Method I wish that I would have been exposed to this method as an elementary student! I believe that this method is simple and easy to understand! It is also a method you could use to help you check your answers and make sure they are correct!

Another method I believe is pretty cool, but a little more complicated to me, is the Russian Peasant Method of Multiplication. This method I believe takes more work than it should. If you don't know what I am talking about here is a short video example -> Russian Method. I think this method takes more thinking than need and I also believe it is more time consuming!

Overall, there are more methods for multiplying, but here are a few you might not have known about! Teaching and learning multiple ways to do a single math problem is important because you might not know what works best for you!

  1. Abby,

    I love the design of your layout. I like how you incorporated through the text links to that method. The images really add a lot as well. Clean and easy to read, yet love the pop of color in the background. With those dreaded times tables did you also have to do the speed tests too? I agree with you 100% that students need to be taught multiple methods. It gives students a way or multiple ways to understand how to compute said math problem.
