Google Meet allows you to have conversations in a simple way where you see the names of people you are talking to, but without clutter. It is similar to Google Hangouts but is for larger groups of people. You need a Google account to use Google Meet. Teachers can make themselves available at agreed times on Google Meet to support students.
