Use Mental Division

In this activity, we will be learning to divide numbers mentally.

Division and multiplication are the inverses of each other. 

This can be really helpful when dividing!

When we know a multiplication fact, we can use this to find two related division facts. 

Let's try an example together. 

Example

Write the missing number

8 ÷ __ = 2

Answer

We know that 2 × 4 = 8

So, using the inverse we can say that 8 ÷ 2 = 4 and 8 ÷ 4 = 2

So the answer is

8 ÷ 4 = 2

Now you know how to use related facts, it's time to try some more questions like this.
