My daughter, 5th grader, had a shit ton of homework tonight.
She worked on it non-stop from the time she got home until bedtime, with short breaks and dinner in between. She wasn't fooling around, and I could see her getting stressed and anxious.
Her last worksheet had 5 unfinished math problems left, so I finished them after she went to bed. That shit was hard! It's been quite a long time since I was a student and I guess I am NOT smarter than a 5th grader! ;)
