What is place value?
We use place value headings like 10, 100, 1000. These help us do sums and see which numbers are bigger than others.
A number is made of one or more digits. The number 6379, for example, is made of the digits 6, 3, 7 and 9.
6 thousands, 3 hundreds, 7 tens and 9 ones (ones can also be known as units).
