3. Place Value: Hundreds Tens and Units It is difficult to see how many objects there are above without counting them. It would be easier to tell how many there were if they had been grouped into Hundreds, Tens and Units.

4. HUNDREDS TENS UNITS So we write: 2 3 4 H T U In this case the 2 is the Hundreds (H), the 3 is the Tens (T) and the 4 is the units (U).

5. Place Value: Hundreds Tens and Units 2 3 4 H T U The place where the digits are put is very important. If we swap the hundreds and tens digit in our example we get a number with a different value. 3 2 4 H T U Remember: If you change the PLACE of the digits you change the VALUE of the number.
