How confident are you that you can fluently multiply multi-digit expressions at this point?

If you are not fluent with your multiplication facts, use a multiplication chart.

Lets start off with 2 by 1 multiplication expressions.

Lets try one a little more complex.

Now lets work on multi-digit multiplication expressions.

The first step is just like you did with a single digit expression. Now, add your zero and do the same process but with the tens place number. Find the sum of both products to get your final answer.
