As of mid August the following in now possible in Classroom:

• Guardian summaries: Teachers and administrators can invite guardians to sign up for email summaries to keep up with their students. Guardians can choose how often to get a summary—daily or weekly—and can unsubscribe at any time. Summaries include a student’s missing or upcoming work as well as new announcements and questions posted by teachers in the class stream.

• Topics for stream organization: Teachers can organize the class stream by adding topics to posts. Teachers and students can filter the stream by topic.

• Teachers and students can preview materials attached to assignments or posts.

• Teachers and students can view email notifications by class using Inbox by Gmail. Important updates from recent emails are highlighted in each bundle.

• Teachers can add a subject when creating a class. (What’s New in Classroom Blog)
