My DD9 still does a fair bit of this (leaves her name off papers, accidentally skips problems, forgets to write units of measure or AM/PM, forgets little things like the fact that she is supposed to underline and circle certain things in certain math problems or write paragraph numbers next to reading comprehension answers). The substance of her answers is right 98% of the time, but she loses points for these little mistakes. It's annoying, but has never been mentioned as a serious concern. I think it's VERY common for the kids in her GT magnet, and in fact I know that she is not considered to have a rushing/careless work problem compared to others in her class. I often take it as a sign that the work is too easy and she's cruising. She doesn't do it enough to lose a lot of points. It's like, 2 points here, 2 points there.
