My daughter had this problem on one of her tests. She forgot to ask her teacher what she did wrong. I understand she did not answer the question in full, but what she did answer I feel is right. Please explain to me the correct answer. Thank you.

question

Hi Mary,

From what I see it looks like your daughter drew the rectangle on the grid and the rest of the handwriting on the page comes from the teacher.

The teacher may have been looking for 4 arrangements

or maybe just the orange pair or the blue pair. I don't understand the relevance of the notation 2 × 4 = 8 so maybe I am missing something.

My suggestion is that your daughter talk to her teacher to determine what the teacher was expecting.
