Again, absolutely! Google Classroom is already a part of your Google ID account and only needs accessed by you to begin setting it up. Google Classrooms can even be used while at school such that it creates a one-stop shop for all documents that your students may need. The students can even go in to the Google Classroom and download the material to his/her Chromebook prior to going home if he/she does not have internet access so that he/she can be prepared for class the next day. Click here on Google Classroom to access the site, sign in with your Google ID and a wizard will appear and walk you through the process of setting up your Google Classroom.
