One way to view
multiplication is as groups
of objects.
For example, 2 x 3 means
that there are  
two groups of three.
This shows that there are two groups of three, as 2 x 3
also can be read as two times three .
We can find the product of 2 x 3 by counting the number
of dots in the two groups of three. 
So, 2 x 3 = 6 3 + 3 = 6

So, 2 x 3 = 6 3 + 3 = 6
This shows that there are three groups of
two, or 3 x 2. 
So, 3 x 2 = 6
How about 3 x 2 ?
2 + 2 + 2 = 6

What can you say about this?
We can see that there
are three groups of three
