This is a generic STAGE COMBAT project that can work with a lot of moves that you've probably taught your class.
It includes both a simple story scenario (about a credit card being declined), and criteria for the assignment.
They're encouraged to be comedic, not serious. More fun this way!
Also included is the rubric that I use for their performance. There's a mark that they give themselves for rehearsal too - I like to do some self-assessments for rehearsals, because they're usually brutally honest with themselves.
TIP - Show them famous fight scenes beforehand to get them pumped! Jim Carrey has a lot of great ones - from Liar Liar, Dumb and Dumber, The Mask, etc!
