Make dividing by even numbers easier

Do you think dividing by 4 is tricky?

It can be easier if you split the number you are dividing in half.

Another way of saying this is dividing by 2

To turn this into dividing by 4, just split each half in half again.

So what you are doing is dividing by 2 and then dividing by 2 again.

Example

24 ÷ 4 = ?

First split 24 in half.

24 ÷ 2 = 12

Then split this in half again.

12 ÷ 2 = 6

So 24 ÷ 4 = 6

What about 8?

If you have to divide by 8, you just split your number in half again.

So you divide by 2 then divide by 2 again then divide by 2 another time.

24 ÷ 8 can be done as

24 ÷ 2 = 12

12 ÷ 2 = 6

6 ÷ 2 = 3
