Using your school's G Suite For Education domain, you can start creating your classes for your students.
Go to classroom.google.com
At the upper left of your screen, click the + sign to create a class. In case you only see the Join Class option, coordinate with your Google Classroom administrator for assistance.
A popup window will appear. You will be asked to input the Class name, which is required. Other types of information such as Section, Subject and Room are optional and will be dependent on the standards that your school may have set for the online learning set up. Click Create when you're done.
Take note of the class code that Classroom automatically generated. You will use this in inviting students to your class. This code is also displayed on the banner of the class Stream.
