One of the issues I have with Google Classroom is the stream. While you can move things to the top, sometimes I feel students have a hard time locating information. Recently Google Classroom introduced the Topic feature. You can now tag (label) each stream item to make things easier to find. The topics appear on the left side on the Stream page (where the class code used to be- you can now find that on the Students page). Here’s a post from Alice Keeler with the details as well directions from Google.
