Sinusoidal Functions Unit Plan

Assessment For Learning

Journal Prompts [C]

  • In your own words, explain what it means for a function to be "periodic".
  • What is the relationship between the amplitude, midline, maximum value and minimum value of a periodic function?
  • In this lesson, we have been introduced to some real life examples that model periodic behavior, including number of daylight hours during a year.  Describe a real world situation that you can think of that can be represented by a periodic function and explain why this situation is periodic.

Learning from Mistakes
Show students graphs created by other students or graphs you've created with mistakes and ask them to correct them. For example, flip the sine graph vertically across the x-axis and ask students how they know it is wrong.
Extension
Similar activities can be done for tangent.
