I teach AP Micro/Macro, I'd like to assign some videos as an introduction before the class starts. A suggestion for the Micro course, I think it would be better to have some of the "basic economic concepts" videos before you start supply and demand, some of them are listed in section 5 under Price System. It is done this way on the AP Micro page under Teacher Resources, but not in the main Micro course for students: https://mru.org/teacher-resources/courses/ap-microenonomics
