educational family co-ops
Schools have a lot of educational support structures built in — classrooms, desks, bells, easy access to teachers… food. Online schools are different, even if we treat them as if they are identical.
The reason you are probably considering starting your own educational family co-op right now is that either your school district is shut down OR you are not comfortable sending the kids to school due to fears of infection. Remember, ultimately flexibility is what will make this arrangement work.
