You can view all of the curriculum, lesson plans, tutorials, etc available to you and assign tutorials to your classes from the "Curriculum" tab when viewing a classroom.
From this page you can go into the different units we provide to view the lesson plans, activities, materials, and tutorials. Here's what CS.1 Getting to Know GameSalad looks like:
You're dropped on the lesson plan for the unit, with the options to view the required materials for each section or to view the tutorial that your students will see once it has been assigned to them.
When you're viewing a unit, you can assign it to your class by clicking the "Assign" button in the upper right (it will turn green once it's assigned).
Any units you have assigned to your classes will show up as green from the top level of the Curriculum tab as well.
