I have ten little fingers

and they all belong to me.

I can make them do things.

Would you like to see?

I can shut them up tight.

I can open them wide.

I can clap them together.

I can make them all hide.

I can jump them up high.

I can jump them down low.

I can fold them like this

and hold them like so.

(This rhyme is all over Google, but I don't know where it originated. My version differs slightly from the ones I've seen elsewhere.)
