In this activity, we will be learning a method to divide by 4 to find one quarter of a number.
One quarter means 1 out of 4 parts.
So find one-quarter of a number, we need to divide it into 4 equal parts, as shown in this bar model.
To work out a quarter of a number quickly, we can use a mental method to divide by 4.
First, we halve the number.
Then we halve that answer.
This diagram shows how to use this method to find one-quarter of 24.
Half of | 24 | is |

Half of |

A quarter of | 24 | is |
|
||
24 ÷ 4 = |
|
Let's try an example question together.
Example
Use this table to find 64 ÷ 4 by finding A and B.
Half of | 64 | is |
|
||
Half of |
|
is |
|
||
A quarter of | 64 | is |
|
||
64 ÷ 4 = |
|
Answer
First, we find half of 64. This is A. A is worth 32.
Next, we find half of A (32), which is 16.
Half of | 64 | is |
|
||
Half of |
|
is |
|
||
A quarter of | 64 | is |
|
||
64 ÷ 4 = |
|
So A is 32 and B is 16.
One-quarter of 64 is 16.
Now that you know this method, it's time to try dividing some numbers by 4.
Good luck!
