Do you know this song?

My American Cuz is trying to remember this song from like 50 years ago. He knows the first verse and then gets muddled.

Can you help please!!

Cuz poem

I’d buy up every school in the nation

And write upon the blackboard big and clear

Indtead of one there will be two vacations

Each vacation 6 months twice a year

And there wouldn’t be no school when it was raining

And I would let you stay at home when it was clear.

Goes on… he can’t remember

If you can please help identify this song, we would greatly appreciate it.

Thanks!!
