Good thought Richard.

I do think, based on the information given (and I'm not questioning you!! lol), that the assignment is not exactly appropriate. I understand that the teacher was probably giving and assignment that he/she thought the students would have fun with, but it seems to have backfired. I know at our school if a parent thinks an assignment is unfair, they usually first call the teacher in question to get an explanation and then if they are not satisfied they contact the principal.
