## Reflection: Connection to Prior Knowledge A New Kind of Graph: The Ferris Wheel Ride - Section 1: Opener: What do these functions look like?

With my mixed-ability and mixed-experience class, each student has a different level of experience and facility with functions.  No matter what, as we begin this new unit, I want to be able to situate periodic functions within whatever understandings my students bring to the table.  Not all of them have a firm grasp on just how important the idea of a function is, but today I will meet my students wherever they are as we practice reasoning abstractly and quantitatively (MP2)about different kinds of functions.  They understand that there are lines and parabolas, and that each of these can be represented with either an equation, a graph or a table.  We'll dip into theserepresentative tools (MP5) to construct a model (MP4) during today's class.
