As a best practice, we recommend for this first session that you are monitoring all students and are able to see their screen view for at least the first session to help them through the program. They'll pick it up quickly, but being mindful about the first session and taking some time will save time and energy down the road.
For your student's first session, be sure to walk them through the program, highlighting the times that you will be reading to them, when they will be reading, and the different buttons they will be asked to use throughout.
