This foldable teaches students what is a function. It starts with an input/output function machine that defines the term function, then moves to a real world example (a vending machine) of a function vs. a "malfunction", then it discusses how to identify a function from a table and graph. This foldable also contains mapping diagrams.
Included is an animated PowerPoint that can be played in class to help the students fill out the foldable and a printable template with the image included. It is a great combo of having students take their own notes, but with a time-saving template.
