3rd grade.
Kiddo went to his teacher to see why his answer was incorrect.

He asked if he could have partial credit for the question, and said that his reasoning was that gravity attracts everything with mass while magnets only attract metal.

She said she wanted him to say “because magnets repel” for question 11. I’m not sure the question is worded specifically enough to warrant that exact answer.

Son is still wondering why his reasoning is wrong.

Thoughts?
