I was helping one of my older school kids (grade 6) with homework this afternoon. She was doing her tables and other math and pages of a math 'text' book. Thing is, she is very bad at math, she was looking back a previous pages to get the answers. She can't help that she's bad at math, but who marks her work? The previous pages have alot of incorrect answers, so she is just copying the wrong thing all the time. She says they mark them themselves - the teacher reads out the answers and they mark if they are wrong or right, but nothing is corrected. She also says neither parent helps or checks her homework.

What's the benefit of it then? If the teacher doesn't check and have an idea of where she needs help, and she's just learning the wrong thing over and over again, then she may as well not do it at all really.

Please help me understand the point, perhaps this is just a bad teacher and this isn't normal, or perhaps there is some benefit I am missing....
