Place Value Lesson 1.1 REVIEW The Place Value Rap
Music by Ben Jacobs, Lyrics by Tim Bedley

The digits, the digits, they each have a name
Memorize ‘em, Understand ‘em is the game
We start at the decimal, to the left we move
Each place is 10 times bigger, multiply ‘em and we prove

The digits, the digits, they fit in so tight
Greater to the left and lesser to the right
Starting at the decimal, sandwiched in between
Zeroes hold the empty places, haven’t you seen?
The digits, the digits, each one means a lot
You can’t leave ‘em out of the place value spot
Reading big numbers each comma’s a word
“Thousand, Million, Billion,” commas, haven’t you heard? Word!

Ones, Tens, Hundreds, Comma
Thousands, Ten Thousands, Hundred Thousands, Comma
Millions, Ten Millions, Hundred Millions, Comma
Billions, Ten Billions, Hundred Billions, Comma
