Numbers to 999

Read, write, compare and order numbers up to 999, and say what each digit is worth.

Every number up to 999 is built from hundreds, tens and ones. In 462 there are 4 hundreds, 6 tens and 2 ones.

The place tells you the worth

The same digit is worth different amounts in different places. In 300 the 3 is worth three hundred, but in 30 it is worth thirty.

This line runs from 0 to 1000. Move along it and watch the hundreds grow.

Worked example

What is the tens digit in 675?

  1. Read the places from the front: 6 is hundreds, 7 is tens, 5 is ones.

    The place a digit sits in is what gives it its worth.

Try it together

Let us build four hundred and six.

It has 4 hundreds, no tens and 6 ones.

    1.Four hundreds — what is 4 × 100?

    Have a go

    Your turn — what is the hundreds digit in 738?

    Hint: Count the places from the front.
