Google Classroom: Schedule ahead, post later

Schedule ahead, post later
"Starting today, teachers can plan ahead by scheduling announcements, assignments and questions to post at a later date or a specific time (great for the early birds who want to get a head start on school planning during the summer ;). Just look for the scheduling option when posting new assignments, questions and announcements. You can find scheduled and draft posts in the “Saved posts” section of your class stream, and you’ll get email and mobile notifications when your scheduled posts go live." -http://googleforeducation.blogspot.com/
