fun multiplication

Hi, I want to share the fun way to learn table’s multiplication.
This video above, give us information how to learn table multiplication by song. That's so wonderful. Let’s see

From the video, you can also conclude that multiplication is repeated addition. Yeah...

Let’s start by thinking about a simple problem like 3 x 2 (“three times two”). it means that meaning the same thing as “three of the quantity two.” By that I mean if you have a box with two balls in it, then 3 x 2 is the total number of ball contained in three boxes that each contain two ball. In other words, 3 x 2 is the same as 2 + 2 + 2, which of course is 6. Aha! So we can just think of multiplication as adding some number together some other number of times, right? Multiplication is just repeated addition.

 And also, you can learn multiplication by games. It's interesting for children to learn about this here
