You are not smarter than a 5th-grader.
At least I can read well enough to know grateful was on the 288er side. She said she would agree it was equal to 2 IF the parentheses that the 2ers imagine were actually there.
The other teacher believes that multiplication is always done before division, which is simply ignorant. She is about as far away from my child as she can be, so I am not worried.
