Act One: a video or photograph to provide a ‘hook’ to the problem

Act Two: further relevant information for solving the problem

Act Three: the payoff from the hard work of earlier acts in the form of a video or photograph that resolves the problem
Each resource employs whichever of the ‘acts’ are necessary to accomplish telling the mathematical story.
