By default, both you and your student will be able to view and work on different areas of the classroom, however if you'd like to make your student look at what you are viewing in the classroom, that's no problem at all!
All you need to do is to click the lock button in the top left hand corner - this will 'sync' both yours and your students view together, so as you move around the classroom, they'll see exactly what you see!
It's important to note that when you apply the lock as a tutor, the student will have limited functionality in the classroom, so they won't be able to draw on the whiteboard (they can still send messages via the chat when in the locked mode). However, all you'd need to do to allow them to have full access is to click on the lock once more, at which point the student will be able to draw or annotate the whiteboards!
