Fill in the Blanks
Here is a fact we should be familiar with...
What is the value of 'a' ?
Type answer...
5
Fill in the Blanks
If we know 6 x 2 = 12
Then we should be able to find
12 ÷ 6 = 'b'
Type answer...

Find the unknown 'A'

Fill in the Blanks
What is the value of A
Type answer...

Fill in the Blanks
If we know
We should be then be able to find out what

We can also use multiplication to solve division and Division to solve Multiplication.
Since we know that 3 x 6 = 18, we also know the related division fact 18 ÷ 3 = 6 or 18 ÷ 6 = 3

Commutative Property Strategy
If we know then we know
11
Distributive Property
We need to find out what 6 x 8 =
but maybe we don't know that fact off the top of our head.
We can break 8 up which could be
5 + 3 since we know our 5 facts.
What would 6 x 5 = ?
What would 6 x 3 = ?
12
Now we know...
What do we do with the 30 and 18 ?
13
We add the totals together...
We broke down the original factor to find smaller familiar factors and added the two totals together.
