Families of Functions using TI-Navigator™ System

Activity Overview

In this Lesson Concept we use whole-class participation in the Activity Center to cultivate students understanding of how the graph of a basic function can vary through the change of a parameter. The classroom-group environment can provide a motivating introduction to this concept, as the students work can embody the range of motion of a base function, and this experience can offer a mental framework for more detailed investigation of particular parameters and values.

Before the Activity

If you are using the TI-Navigator System with the TI-73 you will need the attached .pdf file.

  • Make sure you are familiar with the following TI-Navigator system functions: Send to Class, Collect from Class, Screen Capture, Quick Poll and Activity Center
  • Download the attached activity resource files to your computer
  • During the Activity

    If you use all five Activity Space setting files, students will:

  • Explore Y-Intercept and Parallel Lines
  • Explore Slope
  • Stretch and Shift Parameters for a Trigonometric Function
  • Varying Both Slope and Y-Intercept in Linear Functions
  • After the Activity

    Assess your students understanding by using the Quick Poll feature as desired.
