Functions

These activities are designed for any classroom where students are working on the definition of function.

Grades: 8th - 11th Grade

• Introducing Functions

  Graphs of position over time help introduce the idea that functions have a single output for each value of the input.

• Turtle Crossing
• Graphing Stories

• Functions and Not Functions

  Not everything you can graph is a function; how can we tell the difference?

• Guess My Rule
• Commuting Times
• Card Sort: Functions

• Domain and Range

  The domain of a function is the set of all possible inputs; the range of a function is the set of all possible outputs. Restricting the domain or range of a function is sometimes a useful mathematical technique.
