Lesson: Function Machines Mathematics

Students will be able to

• use one-step function machines to
  • input a number into a function machine and calculate an output,
  • work out the function rule from a set of inputs and outputs,
  • calculate an input from the function rule and the output,
• use two-step function machines to
  • input a number into a function machine and calculate an output,
  • calculate an input from the function rules and the output,
• solve more complex problems, such as replacing a two-step function machine with a one-step function machine, choosing the correct function rules for a two-step function machine from a set of multiple choices, or calculating an output for a three-step function machine.
