Our 15-year-old must wear a mask at school. “Fortunately”, he only goes two days a week with it. I say “fortunately” because my biggest complaint is his seeming lack of education content versus going five days a week. Now, he goes two days, does two days of online, and apparently Wednesday is completely off. On any one day, he works approximately 2 hours and has no homework. We’re seriously considering doing home school next year if they continue this crap, as he’s not being well prepared for college.
Now, to your point: He doesn’t seem to be suffering any ill effects to his two days of mask wearing. My preference would be he not wear them at all — another benefit of home schooling that is appealing...
Homeschool him now. He is not getting content because he is not being taught anything. Get him home and into some meaty Interesting things and some work
