Classroom is available to anyone with Google Apps for Education. Google Classroom helps teachers create, assign, and collect student classwork and homework paperlessly. With Google Classroom, teachers can seamlessly integrate Google Docs, Google Drive, and Gmail to create assignments, provide feedback for in progress and completed work, and communicate with their students directly and with whole class announcements--all without using a single piece of paper. Students can work on assignments in Google Docs and turn it in with a few clicks.
When teachers create assignments, folders are automatically created in Google Drive for each student. They can choose to share a single document (like project instructions), or automatically make a copy for each student (like a project template). They can see who has completed the work at a glance and assign grades. Students can easily see due dates on their assignments page, so they can stay organized and submit work on time.
