# Value for money

This sub-collection of materials of the dy/dan collection contains three resources that bring mathematical storytelling to the classroom in the context of ‘value for money’. Resources comprise:

• 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.
