Chromebooks allow for offline access to documents, enabling students to create and update their work when they are without an Internet connection. In order to set this up, students must enable Offline mode on their Chromebook. This will only sync part of your recent files.
Any file that is accessible in Google Drive can be made available for offline use. Directions are shown below.
