A lesson is a page of content and questions that students work through, and that Mindjoy marks for you.
Making one
Open My Library, click Create, then Lesson. You can build it with the Educator Agent, copy one of your own, or start from scratch.
Writing it
Type into the page. Insert questions and media with the slash menu.
Checking and publishing
Use Preview to walk through it as a student, then Publish.
Assigning it
Click Assign and pick your classrooms. Set a start and end date if you want them.
Then watch the marking come in on the classroom's Assignments tab.
