If you are just starting out with Google Classroom then please read the 6 earlier posts from this year
It is great to see several new features that have been released such as the video shows above, where through the new app you can take pictures of work and instantly upload and attach to classroom. This is great for students who want to evidence something in their book or outside the physical classroom.
There are several other new features which you will be pleased about such as:
There is now a master teacher assignment page where all active assignments are aggregated in one place
There is now also a way of working on Google classroom offline which syncs when you connect.
You can read and watch the new features here
