How educational, exactly, are prom, senior picnic, or the yearbook? Senior pics? Senior trip? No. None of those are included in the "education" part of "free public education", and they're most assuredly not covered in the "free" part, either.
I doubt you've been told that she won't graduate if she doesn't pay for extra-currics and a yearbook. That's illegal in every state in the Union. If you don't pay, she doesn't get a yearbook, doesn't participate in senior week. She not entitled to those unless she pays for them.
