As of January 2021, Adaptive Learning modules (blue tiles in the content gallery) are available only through an app available for iPads and Chromebooks. You can learn more about downloading the iOS app here and the Chromebook app here.
Students must have the app installed on their compatible device in order to complete Adaptive Learning assignments. Teachers do not require the app, but can use the web-based teacher dashboard.
