One thing that was useful for me this year was the ability to have people sign up for times on my calendar so we can meet. They could easily see if I was available or not and when they selected the time they wanted to meet, that time was automatically added to my calendar. I used https://gb.youcanbook.me/ for my site but you can do a very similar thing just using Google Calendar.
This could be very useful for teachers who have students sign up for times to present or to take a final. By using a digital version this means that it will be added to both calendars and reminders could even be set up. You can have a digital file that is visible to everyone you want it to be so that everyone knows when they can sign up.
Watch the video to see how to do this using both Google Calendars and Youcanbook.me.
