A Place Value Story
sung to the tune of
Old MacDonald Had a Farm
The Place Value Community
When reading place value
Think of houses
Lined up in a row
And in each house are families of three
Their first names are all the same
Ones, Tens, Hundreds
Ones, Tens, Hundreds
Ones, Tens, Hundreds
And on it goes
100
Hundreds
10
Tens
1
Ones
All family members have the same first names
Ones, Tens, Hundreds are they
The Whole Numbers
Decimal
Now find the decimal,
Then look to the left
That’s where the whole numbers live

The
Billions
Millions
Thousands
Units
Each house has a different family
All with a different surname
(Last name)

To the right of the decimal,
The houses are mirrored
So the families reflect those of the left
100

Ones
They also have family
Named Ones, Tens, Hundreds,
Except for that very first house……..

It’s a sad story……..

No surname

Tenths
