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

Let’s take it to the right of the decimal point

We’ve got tenths, hundredths, thousandths, ten thousandths

Smaller than a 1 with a T H Vocabulary ten-thousandths

number that can be written as a product of tens

base

the number that is used as a factor when evaluating powers

the large sized number exponents

the number in a power that tells how many times the base is used as a factor

the small sized raised number Tips If the exponent is a positive draw that many blanks with the base in front

1 x 10 to the 4 is 1_ _ _ _

Then you are ready to add the other numbers in their spots. Remember what ever is the exponent that is the number of blanks that need to be behind it! if the exponent is negative then that is exactly the number of spaces behind the decimal.

1 x 10 to the negative 4 is ._ _ _1
