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.

Fill in the Blank

Solve this multiplication expression

25 x 3 = ?

Fill in the Blank

65 x 8 = ?

Lets try one a little more complex.

Fill in the Blank

1,256 x 7 = ?

Fill in the Blank

6,184 x 6 = ?

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.

Fill in the Blank

67 x 57 = ?
