Everybody's doin' the Action Fraction!
Gettin' mathematical satisfaction!
Dancin' a radical new sensation!
Sweepin' it's way across the nation!
Reach up high as you can go.
Bend down low and touch your toes.
Lift your hands half way up,
And mark the middle with a clap, clap,
clap.
Reach up high as you can go.
Bend down low and touch your toes.
Lift your hands one fourth the way.
Snap your fingers, step and sway.
Reach up high as you can go.
Bend down low and touch your toes.
Lift your hands three fourths the way,
Jiggle and shake 'em any old way.
Turn one third and wave your hand.
Turn another third and wave once more.
Turn another third and you're right back
home
Ready to what you did before.
Everybody's doin' the Action Fraction!
Gettin' mathematical satisfaction!
Dancin' a radical new sensation!
Sweepin' it's way across the nation!
