Click the toggle from 'Unassigned' toggle to Assigned. It is as simple as that!
When a lesson is assigned to students, they can access the lesson video and the individual activities on their portal. You can assign the entire lesson by clicking on any of the toggles that are available in the lesson page.
If you do not have a group of students, you will first need to create a group and add students to the group before you can assign the lesson.
Please note that it is not possible to assign a lesson or a theme to an individual student within the group. This can only be done for the entire group.
