Here are a few tips when setting up your child's workspace:
-Noises-they may seem quiet to you, but background noises are easily picked up by microphones in online meetings. Try to limit as much background noise (TVs, siblings, wind chimes, etc).
-Distractions-having a sibling (or pet, or sometimes event a parent) moving around behind a student can be distracting to others in the meeting, try to set up in an area with few visual distractions for your child and others.
