Adding materials is a great option when needing to store something on the About page where students can come back and reference to whenever they need. For example, many people add their daily schedule, classroom norms, and a syllabus just to name a few. Here is the process to add resources to your About page.
When adding a resource, Classroom gives you the ability to attach a document from your computer, pull from your Google Drive, attach a YouTube video, or attach a link to somewhere on the web. All options can be very effective in sharing digital content with your students in one central location.
