If you're wondering why there's a one on top

You'll know the answer when you realize I'm one big block, I'm one big perfect ten

I'm a ten block, I'm a ten block

You might think we're different, think again

We're more alike than you suppose

You're one, one, and I'm ten ones, which means

I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

Two is made of two blocks

I'll always be your friend

Three will entertain you, on that you can depend

I'm two ones, and I'm three ones

And I'm ten ones, which means

I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

Four is made of four blocks

I love to be a square

Five is made of five blocks

High-five there and there

I'm four ones, and I'm five ones

And I'm ten ones

Which means I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

But why have you got that round thing next to your one?

It's a zero

I need my zero hovering in space

It's there to keep my one in place

And if you're wondering what it's for

It shows you I'm not one

I'm one ten and nothing more

Six is made of six blocks

I like to roll the dice

Seven is made of seven

In a rainbow

That looks nice

I'm six ones, I'm seven ones

And I'm ten ones, which means

I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

Eight is made of, octoblock

And if you add one more

Nine is made of nine blocks

I'm a bigger square than four

I'm eight ones, and I'm nine ones

And I'm ten ones, which means

I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

I can be two lots of five or five lots of two

In other words, five pairs

I can be one and two and three and four

When you need to go upstairs

I'm a ten block, I'm a ten block

You might think we're different, think again

We're all just made of counting blocks

You're one, one, and you're ten ones

Which means I'm one ten

One, two, three, four, five, six, seven, eight, nine, ten

Yay! Hurray!
