My district had already given all high school students Chromebooks; when they announced the closures they provided all students (K-12) with the same. For families without internet access, hotspots were acquired and distributed. It was great! Having done all this, though, they forbade the instruction of any new content and closed the grading system.

Teachers still do videoconferences via Google Meet and/or Zoom, but it's mostly for social interaction rather than teaching.
