Decimals to Fractions Song | Decimal Notation

Numberock's Decimals to Fractions Song will teach your 4th Graders how to connect decimals to fractions while providing the foundation for understanding decimal place value and further fractional relationships, which they will likely be exposed to in 5th Grade and beyond.

When this concept is mastered, your students should be able to understand that a decimal such as 0.7, for example, can also be represented by the fraction 7/10 and vice versa. Students in 4th Grade are suggested to be able to understand decimal to fraction relationships by moving to the right of the decimal point as much as two places, ie, the tenths and hundredths place.

It's also important to understand that any number can be represented in decimal notation. Think about how even a whole number such as 25, for example, can be represented as a decimal. 25.00 and 25.0 are examples of how the number 25 can be represented as a decimal, despite its whole number status. We actually see this example all the time in our daily activities when it comes to representing values of money. Oftentimes, a whole number value of money, such as $25, is represented in decimal notation as $25.00.

Decimals to Fractions Lyrics

Verse 1
If you split the number one into ten parts,
that’s where the decimal place values start.
They’re values less than one - they’re quite small -
like zero point one, which is a decimal, y’all.
This number as a fraction is one over ten,
and zero point one is it’s decimal equivalent.
Fractions over ten, one hundred, one thousand and on,
are all decimal numbers - it’s a phenomenon.

Prechorus 1
Decimals are fractions, just with different names.
They each have a value that’s exactly the same.

Chorus
Whole numbers to the left! Decimals to the right!
They get smaller and smaller, ’til they’re barely in sight.
Like whole numbers can get big, decimals can get small;
if you know place value, you can imagine them all.

Verse 2
On a place value chart, you’ll see a pattern starts
if you split one tenth into ten equal parts.
This new value is one hundredth, and in every case,
one hundred hundredths equals one whole in the one’s place.

Prechorus 2
When any denominator is a power of ten,
that fraction can be written as its decimal equivalent.

Bridge (rap)
We’ve got the tenths, the hundredths, and more…
Let’s imagine a number line to further explore.
You see, there’s a special land between zero and one
where you’ll find decimal numbers, and every fraction.
Between zero and one, make ten intervals:
these are tenths, written as fractions or decimals.
When counting by tenths, after you get to nine,
the tenth tenth makes one whole on the number line.

Let’s see what happens as the place value decreases,
and one tenth is divided into ten equal pieces.
We get a hundredth; written as point zero one;
and ten of these make a tenth, but we’re not done!
Every ten hundredths makes another tenth on the chart
then something special happens at the ninety-ninth equal part...
Because at ninety-nine hundredths we’re one hundredth away
From one whole, or one hundred hundredths, you could say.
