Well it was introduced as "absolute value uses lines on each side. It means you drop the negative if there is one". I asked what the point of it was, cause it sounded sorta useless. Instead of saying "OK, well, how would you express distance, x1-x2?", she was just stuck. I suppose that's what happens when you have general teachers that don't really know maths or science, don't really feel that it's interesting and offers amazing ways to look at the world. In fact, I'd be surprised if she actually knew beyond what she was teaching. It's not like middle grade teachers have to take advanced courses, and they do have a wide workload.
