Any time my 6th grader (stepson) asks me a question, I say "that sounds like a great thing to look into" and make him go look it up for himself, then tell us about what he found out, what his source was, if there are any other things he learned that were interesting/might want to look into more...
He's groaning every time, and I just remind him this is basically school right now; how lucky for him he's getting to research things he actually wanted to know. 4th grader is doing ok with BrainQuest books and things like that, plus some online stuff they already had available.
At this point the state is basically putting their hands up; there isn't enough equitable opportunity for them to mandate online curriculum. Teachers are sending out some resources, but it can't be for grades. I won't be surprised if they just call the school year from here and then pick things back up in the fall. It's a very frustrating thing to imagine, but it also makes sense - otherwise we're basically endorsing systemic favoritism of those who can 'afford' to be educated that way. Usually I'm not a fan of sacrificing the good for the perfect, but from a public education standpoint I truly don't know how they could set standards/expectations in place KNOWING that the most underserved/at-risk populations couldn't comply.
