How to make multiplication tables with the help of a grid
Now we’re going to take a look at how to make multiplication tables with the help of a grid. The first thing we’re going to do is create a 10×10 grid (if you want to make a multiplication table for numbers larger than 10, you’ll have to make a bigger table).
We put the zero in the bottom left corner, like so. This is the point that we start to count from.
Let’s look at an example: 3 x 4
To solve the multiplication, we need to count vertically the same number of squares as the first number that we’re multiplying. In this case, we’re going to count 3 squares.
Now we do the same with the second number that we’re multiplying, but this time we count horizontally. Once we’ve counted 4 square horizontally, we get something like this:
We color in the area outlined by the two numbers. To work out the result of the multiplication, we need to count the number of colored squares.
The result is 12 squares. Therefore, 3 x 4 = 12
