This is how most schools are handling it. Some combo of things like Google Classroom, zoom/webex/meet meetings, and various other apps & sites and online activities. They prescribe book reading, art & PE, but those are hard to track so they're typically not part of an online curriculum.

You also need to understand that if a kid has 2hr worth of work online, the odds are good they'll sit in front of the computer all day unless someone is supervising them. This is the real issue, especially for younger children.
