I wanted to show a quick view of the Google Classroom on the iPhone from the student perspective. I've been doing a bit of experimenting to see exactly what students can and can't do. In the end, there is very little in the can't category when you realize that photos can take the place of nearly anything.
So go ahead, take a quick tour as though you are a student and see what the app can do. Also, as a teacher, you will be able to add Announcements into the stream directly from your mobile device. I'm sure you'll be able to add assignments soon but as of this video, not yet.
