Fraction Rap. Using rap music, two 6th graders teach fractions, percentages, decimals, ratios and rates for a math project in the Academic Arts Academy program at their school.

The Fraction Rap
Lyrics:

Let's get this party started with the parts of fraction
Set your mind at ease so there's no distraction
Numerator on top lookin' mighty fine
While the cool denominator's chillin' under the line

If a number can go into both multiple times
It's livin' too large you gotta simplify
Though they look different don't be goin' insane
They're really just equivalents that means they're the same

If the top number's equal to or greater than the bottom
They're improper fractions, mixed numbers don't got 'em
How many times the bottom goes into the top
Makes a whole number plus a fraction... that rocks!

The number's mixed, the number's mixed
A whole number and a fraction is a number that's mixed

Everybody knows that two halves make a whole
Add a third and a half, now that's not so simple
First you gotta go find the lowest denomin-
Nator that the numbers under both have in common

Two goes into four, but three does not
Three goes into six, so does two... that's hot!
What you do to the bottom, gotta do to the top
Two-sixths and three-sixths is five-sixths... now that pops!

Adding fractions, adding fractions
Lowest common denominator, same with subtraction
Adding fractions, adding fractions
Lowest common denominator, same with subtraction

When you multiply fractions start with the two numerators
Write the answer down and move on to the denominators
Now you simplify, or cross-simplify 'em first
Like equivalent fractions in our earlier verse

When dividing two fractions flip the second one around
It's reciprocal, just multiply 'em now
When dividing one fraction with the top number smaller
It's a decimal like pennies from a dollar

When there's a percentage you can write a hundred under
Now it's called a ratio comparing two numbers
If it took two minutes forty verses from the top
Our rate is twenty verses per minute... non-stop!

Twenty to one, Twenty to one
Our verse-to-minute ratio is twenty to one
Twenty to one, Twenty to one
Twenty outta forty equals fifty percent

Fractions
We use 'em everyday
Fractions
We'll help you get an 'A'
Fractions
A shout to Miss Solie
Fractions
While I'm drinking some tea
(which I do almost every day in Ms. Solie's class) :-)
