Here is Amy’s explanation for why the commutative property of multiplication is true for counting numbers:
Whenever I take two counting numbers and multiply them, I always get the same answer as when I multiply them in the reverse order. For example,
It always works that way; no matter which numbers I multiply, I will get the same answer either way I multiply them.
Discuss why Amy’s explanation is not complete. Then explain why the commutative property of multiplication is valid by viewing arrays in two ways.
