First off thank you all for your resources in the trying times.
We flipped our classrooms a few years ago, not fully, but here is a link to our blog with access to lessons and videos we have recorded. Hopefully some of these will help you out as well.
Under the teacher resources page there is a video presentation on how to use Google Classroom to teach art.
Also feel free to use our youtube channel: https://www.youtube.com/channel/UCuHwR8jtrcf-jOp7kI4OH-A
