Multiplication

Let's see what's really going on when we multiply two numbers.
2x3=
This means that you have two groups of 3!
6 triangles split into 2 sets of 3 triangles
Put the two groups together...  How many triangles do you have?
6 triangles
Count them...  One, two, three, four, five, six!
So, our answer is:
2x3=6

Let's do another one!  This one has the numbers switched around.
3x2=
This means that you have three groups of 2!
6 squares split into 3 sets of 2 squares
Put the three groups together...  How many squares do you have?
6 squares
Count them...  One, two, three, four, five, six!
So, our answer is:
3x2=6
Hey, that's the same answer we got with 2 x 3!  But, we put the six together a different way.  Look at them both again to see the difference!
