Children return to school Mon 8th April

This week in Year 4, we have started our new topic ‘Decimals’.

Decimal numbers are numbers which are not whole. For example: 11.5 is a decimal number, between the numbers 11 and 12. That means that the number 11.5 is more than 11, but less than 12.

We use decimals for many different things, such as:
– Time (seconds)
– Money
– Weight
– Length

Take a look at this number

There are 3 ‘tens’, 4 ‘ones’ and 7 ‘tenths’.
The decimal point is placed between the numbers 4 and 7.
The decimal point separates the whole from parts of a whole.
Tenth = One whole is divided into 10 parts.
Hundredth = One whole is divided into 100 parts.

Have a go at completing the ‘What are decimals?’ quiz below:
