If your students have iPads, smartphones, video recording/editing software...and if you have a way for them to submit or show their work to the class, then this is an incredible unit review activity for YOU...!
This activity can be used with ANY subject matter, as long as you have something you need to review/re-learn, and a way to record, edit and present.
-One, fully editable, Word document with a checklist for actions to capture on video.
-Funny ideas to capture students' creativity as they review for one of your chapters, or even as they review for a semester or annual exam.
-Several open-ended spaces (within the checklist) for student input. This has been intentionally left blank to encourage a whole-class pre-discussion and earn student buy-in of the project.
-Length of time (you decide, but I'd allow a couple of weeks)...?
