Ten Fingers

If I didn't have 10 fingers,
I couldn't count to 10...

I always use my fingers,
They're better than a pen!

If I didn't have 10 fingers,
I couldn't even add,
Without my trusty fingers,
My math is really sad!
I use those handy fingers,
Please don't ask me why,
I use those handy fingers,
Like stars light-up the sky!!!
But now my teach is saying,
Do it in my head!
If fingers are forbidden,
I'll use my toes instead!
