Unless the problem stated that they are supposed to solve it a certain way, then that doesn't make a whole lot of sense. I would take a red pen and circle the problem and put a question mark and send it back in.
Nope, no requirements to solve it a certain way. It was a story problem and no specific directions except to put the answer in the blank space.
I thought about sending it back in with a note asking why it was marked wrong. She is not the most flexible teacher. Dd says she reminds her of the cheerleading coach from Glee.
