There are three main ways to use Mote with Google Classroom:
1. Providing Private Comments for individual students, using the Document view (See below) or 'Student Work' view.
2. Making an announcement, or providing Class comments on assignments.
3. Creating an assignment, using 'Sticky motes' and our Share to Classroom functionality. For more on this, check out this article
IMPORTANT - One limitation of Google Classroom is that comments added to a Docs or Slides template are not copied when you use the 'Create a copy for each student' option in Google Classroom. Read more here
Document view private comments (for any document including pdfs and images)
