Form a Line using TI-Navigator™

Published on 06/09/2008

Activity Overview

In this lesson concept we use the Activity Center to build some basics in students understanding of linear functions. The linear relationship is clearly one of the big ideas of the algebra curriculum, and it paves the way for a deeper and more rounded understanding of the concept of function in general.

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

    Students will:

  • Gain a qualitative, experience-based sense of slope and y-intercept as attributes of the rules that correspond to linear functions
  • Investigate slope as a relationship between the coordinates of two points that obey a linear rule
  • Gain familiarity and fluency with the linear functions and their equations, by doing manual linear fits of class-created data
  • After the Activity

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