Children are expected to work with even larger numbers in Year 5, including millions. Many will have difficulties in reading and writing such large numbers and will need a lot of help to appreciate the place value of each digit.

The easiest way to read large numbers is to think of them as blocks of three, starting on the right.

Each block of three is hundreds, tens and units, which keep repeating themselves.

**The first block of three are HUNDREDS, TENS AND UNITS of ones or units.**

So 456 is four hundred and fifty six (*units*).

**The second block of three are HUNDREDS, TENS AND UNITS of thousands.**

So 456 456 is four hundred and fifty six ** thousand** four hundred and fifty six.
