Of course grades are fairly meaningless in elementary school, unless they are so bad you're needing to repeat a year. Being sick for a few days won't cause that. At that level grades are mostly just feedback to the parents. As a parent, if my 4th or 6th grader got a lower grade due to missing homework as a result of being sick, it wouldn't concern me. In high school it starts to matter more due to grades being a component of college admissions, but unless you're targeting really elite schools a couple of days of missed work isn't going to move the needle much. And if you are targeting elite schools, you're already working very hard and including a lot of AP courses and extracuricular activities and you will just buckle down and make up the work.
