Clear your lesson progress before 1st day of each new class so that you can complete activities 1-4 together as a class. You can find the "Clear Lesson Progress" by clicking "Preview Lessons" to enter lesson 1 and it will be at the top right of the platform above the progress bubbles. All of the lesson progress will be deleted except for the "create" project if you have completed one. You "create" project will remain on the class page.
