Use Classroom add-ons

This article is for teachers.

You can use add-ons within Classroom to share engaging activities and content with your class. Add-ons can be attached to assignments, quiz assignments, questions, materials, or announcements.

You can choose from any add-ons your admin has installed. You can also install add-ons yourself if your admin has allowlisted the add-on for you to install.

If you're looking to find more add-ons, contact your admin.

What you need to use add-ons in Classroom

  • You must be using Google Workspace for Education Plus or the Teaching and Learning upgrade.
  • You must install the third-party Classroom add-on in your account. You may need to contact your administrator to install the add-on. Learn more about admin permissions for Classroom add-ons.
  • Add-ons can only be created and assigned on the web version of Classroom.
  • Add-ons can be viewed, completed, and graded on both the web and mobile versions of Classroom

Create an add-on attachment with third-party integration

With third-party providers, you can create add-on attachments on their website or application. A new assignment is created with the selected content attached as an add-on if the provider supports the functionality.

Important: Add-on attachments can't be created with the Share to Classroom button.


My add-on isn’t working. What could be wrong?

If your add-on isn't working, it's possible that a pop-up blocker may have caused the issue. You can report the issue and check with your IT administrator to help investigate it.

I can’t create an add-on attachment from a third-party site or application.

Make sure you meet requirements for using Classroom add-ons. Learn what you need to use add-ons in Classroom.

If you meet the requirements and still cannot create add-ons from a third-party site or application:

  • The third-party add-on may not support creation of add-on attachments from their site.
  • The third-party add-on may need troubleshooting by the third-party creators. Reach out to the third-party provider directly to troubleshoot any assignment creation issues or to request support for add-on attachment creation from their site.
Important: If the third-party site or application doesn't create the assignment for you, you can still create the assignment and attach it in Classroom. Learn how to attach your content to a Classroom assignment.
Is any Classroom information shared with add-on attachments?

Add-on attachments can read and modify certain information about the Stream item to which they’re attached, such as the assignment title, description, due date, and maximum score. If attached to an assignment, they may turn in, unsubmit, or return a student’s submission.
