One plus one is two
Two plus two is four
Three plus three is six
And four plus four equals eight
Five plus five is ten
Six plus six is twelve
Seven plus seven is fourteen
And eight plus eight equals sixteen
Nine plus nine is eighteen
Ten plus ten is twenty
Eleven plus eleven is twenty-two
And twelve plus twelve is twenty-four
Let's learn how to double on the space shuttle
We'll discover stars never seen by the Hubble
And count them in couples to add the double
Now we're touching down on land
Finding doubles wherever we can
Two koalas in a huddle
Two is one plus one's double
Two crabs with four pinchers
Come out of their little tunnel
Three-toad rhino feet make six
Toes making the ground rumble
Two cats with four legs make eight
Legs in a cuddle
Two starfish with five arms
Make ten arms in a puddle
Two ducks lay six eggs
As all twelve start to rustle
Two branches with seven leaves make fourteen
As pandas chuckle
Two octopi's eight arms make sixteen
Moving near a bubble
On the beach two buckets of nine
Make eighteen mussels
Two sheep's ten fingers make twenty
Hairy monkey knuckles
Seven ants on two hills make twenty-two
Ants that bustle
Four frogs on each of two lily pads
Twenty-four frogs croak and grumble
Let's learn how to double on the space shuttle
We'll discover stars never seen by the Hubble
And count them in couples to add the double
One plus one is two
Two plus two is four
Three plus three is six
And four plus four equals eight
Five plus five is ten
Six plus six is twelve
Seven plus seven is fourteen
And eight plus eight equals sixteen
Nine plus nine is eighteen
Ten plus ten is twenty
Eleven plus eleven is twenty-two
And twelve plus twelve is twenty-four
