While we might not be able to see our coworkers in person, remember that our kiddos cannot see their friends face-to-face, either. So online apps can be a critical component of connection.
Schedule a time once or twice a week (or more if your student can handle it) to connect online with their peers. They can chat about schoolwork or nothing pertaining to learning, but transition to homeschooling can be hard on them so the connection is important.
For us, too, we can do an online conference call to connect with our coworkers, ask questions, and check in.
