Cartesian Exploration using the TI-Navigator™ System

Activity Overview

In this activity sequence, using the TI-Navigator™ system, students control points in the xy-plane. Exploring this space freely and responding to prompts, the students will develop understanding and intuition that will guide their use of graphing in Algebra throughout the year.

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:

  • Collectively explore the Cartesian coordinate
  • Draw conclusions about the coordinate system based on their exploration
  • Begin to make connections between their individual point on the grid with the collective classes? points
  • After the Activity

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