The Domain and Range Song World Premiere! [Video]

Season 2, Episode 1:

Here are the lyrics to the song:
To the tune of “Irreplaceable” by Beyonce

To the right, to the right
To the right, to the right
Everything in the domain from the left to the right

On the graph, domain’s the x
From least to greatest, and here's what's next
I'm talking about the range--that's the y
how far up and down the graph goes at the same time
Put those in order from least to greatest too
So you can answer the questions that I gave you

Sitting in Mr. D's class, thinking bout how he's such a fool,
How we'll never ever forget how to do
domain and range yeah

You must now know domain, you must now know the range
I can help you understand in a minute
Matter fact, you’ll pass the test in a minute, baby

You must now know domain, you must now know the range
I can help you understand for tomorrow
So don’t you ever for a second ever forget, domain and range!

So when you have a coordinate point
A pair of (x, y), just remember this
Baby the first number’s the domain,
The second number’s the range
Cause the truth of the matter is… domain and range are so is easy!

Read about how I originally used this in class in Teaching Domain and Range (with a little help from Beyonce), and then read even more about it from my 2008 book, Ten Cheap Lessons: Easy, Engaging Ideas for Every Secondary Classroom.
