You can get step-by-step directions of how to use Classroom by Google by clicking the below links. Here is an example of how detailed Google's instructions are:
As a teacher, one of the first things you will do in Classroom is create a class for each of the classes you teach. In a class, you can add students, create assignments, post announcements, return reviewed assignments, and send messages to students.
Classes are interactive for students, too. They can comment on announcements that you make, share a post with classmates, or return an assignment.
To add a class:
- Sign in to Classroom at classroom.google.com.
- Click + at the top of the page and click Create class.
- Enter the class name in the first text box.
- Enter a short description in the second text box, such as section, grade level, or class time.
- Click CREATE.
After you create a class, you can choose the image that is displayed for the class in the stream. To change the image from the default:
- Open the class and click Change Photo at the bottom of the image.
- Select an image from the gallery and click Pick Course Image.
Note: At this time, only the teacher of a class can change the image in the class stream.
You can also display a profile photo next to your name in both the class stream and on the class card on the home screen. Classroom uses your Gmail profile photo as your Classroom profile photo. See Selecting your Gmail picture for instructions on adding a photo.
From the home screen, you can rename or delete a class using the menu icon (three vertical dots) in the upper-right corner of the class card:
- To rename a class, click the menu icon and select Rename. Enter a new name and click SAVE.
- To delete a class, click the menu icon, select Delete, and click DELETE.
