How do I interact with the teacher?

You will be able to interact with your teacher much the same way as you do in a classroom. You and your teacher will be able to see and hear one another via video. If you have any issues, then you can also write to your teacher in the chat box privately to make them aware of these. Likewise, you can also write to classmates in the chat box if you are doing a group activity, like brainstorming.
