Explain how you can break apart 3times 9 to help you multiply.

Why would you want to break it apart? Memorizing the multiplication tables is by the far best way to multiply.

I suppose you could multiply 3 times 3 and then add the answer three times. But that seems like an awkward way to solve this problem.
