In this activity, we will be halving numbers.

Example

Do these questions mentally and as quickly as you can.

What is 262 ÷ 2 ?

Answer 

131

The quickest way to do this in your head is to split the numbers into 200, 60 and 2.

Half of 200 is 100, half of 60 is 30 and half of 2 is 1.

We have 100, 30 and 1.

Add them together and we have 131.

Easy isn't it!!
