Have you invited parents to your Google Classroom? The Add Guardian feature came out in the fall. You need the parent's email address to invite them and then they need to have a Google (but not necessarily a Gmail) account to accept. They do not have access to your classroom but rather can select a daily or weekly summary of events. Here’s a sample of a weekly summary (yes, I signed up as a parent). If the student is in more than one Google Classroom, all the summaries will appear in one email.
