Google has just announced some awesome updates for Google Classroom.
The mobile app allows students and teachers to take a photo and attach it to their assignment (really useful), attach images, PDFs and web pages from other apps to their assignments, and offline access to their assignments and streams.
Another new feature is the Teacher Assignments Page. This page gives quick access to all assignments and status across all classes.
The other new feature is another heavily requested one, Archive Classes. This allows you to move your old classes out of the main page, but still allow you to access information in them. Teachers and members can view archived classes, but cannot make any changes or turn in assignments.
