I would circle the problem as a reminder to your DD to ask the teacher to show her how to solve it. Whenever my DD gets a correct answer marked as incorrect, I have her do this and two results usually occur: 1) She learns what she was missing and is able to fix her mistake (whether it be in calculation or in the process if the actual bottom line answer was correct) or 2) She is able to discuss with the teacher and the teacher realizes she does know what she is doing and changes it to correct. Math is usually black and white, but sometimes a little shade of grey creeps in.
