Pi Day (March 14 or 3-14) is a day to celebrate our favorite number, 3.14159.... The marvelous mysteries of this number could be probed forever, but we will limit ourselves to some carols you can sing on our numbers own special day, perhaps even at Pi o'clock that afternoon.

These Pi Day songs were written by LaVern Christianson, when he was a math teacher at Windom Area High School, Windom, MN, USA, with some help from his colleagues. They have been sung by his classes, and by the classes of other math teachers in Windom for several years now. Since this site first appeared, we have recieved reports of many other teachers using them in thier classrooms, as well. We hope you enjoy. Sing heartily!

Happy Pi Day

Happy Pi day to you,
Happy Pi day to you,
Happy Pi day everybody,
Happy Pi day to you.

(to the tune of "Happy Birthday")

Oh Number PI

Oh, number Pi
Oh, number Pi
Your digits are unending,
Oh, number Pi
Oh, number Pi
No pattern are you sending.
You're three point one four one five nine,
And even more if we had time,
Oh, number Pi
Oh, number Pi
For circle lengths unbending.

Oh, number Pi
Oh, number Pi
You are a number very sweet,
Oh, number Pi
Oh, number Pi
Your uses are so very neat.
There's 2 Pi r and Pi r squared,
A half a circle and you're there,
Oh, number Pi
Oh, number Pi
We know that Pi's a tasty treat.

(to the tune of "Oh Christmas Tree")

Pi Day Song

Refrain:
Pi day songs
All day long.
Oh, what fun it is,
To sing a jolly pi day song
in a fun math class
like this. (Repeat )

Verse:
Circles in the snow,
Around and round we go.
How far did we have to run?
Diameter times pi! (Refrain )

(to the tune of "Jingle Bells")
