Look at the following place value chart.

Periods → Thousands Ones

Places → Ten Thousands Thousands Hundreds Tens Ones
(TTh) (Th) (H) (T) (O)
Value of places → 10000 1000 100 10 1

The ones period has three places – Ones, Tens and Hundreds.
The thousands period has two places – Thousands and Ten Thousands.

Let us write 51648 in the place value chart and see how it helps in us read the number.

Thousands Ones

Ten Thousands Thousands Hundreds Tens Ones
