You know better than I, but I think you mentioned that you live in Gulf Shores. Is there a reason you and a few other parents can't get together at least once or twice a week in the evenings on the beach or wherever and let the kids be kids as best as possible under the circumstances? Also, as much as possible, have your daughter use Zoom or Meet to talk to friends, rather than using Snapchat or texting. It's not the same as being in-person, but it's better than faceless, limited communication. I had students who stayed on or arrived early before class started to talk on Meet. It helped.
Talk with the gifted and talented teacher. They're trained to invidualize instruction. Tell her/him your concerns and ask how you and she/he can plan meaningful and challenging lessons. It's very hard for a teacher to not rise to the occasion when a parent says, "How can I help?"
Don't expect any word on how your school will plan to run classes for another week or more. They're watching this second wave closely and waiting on state and county health departments/agencies to give more guidance.
