Where’s the Point?

Activity Overview

This activity can be used to introduce students to the Cartesian plane. They should have some familiarity with how points are located in the plane using two coordinates, but the emphasis in this activity is solidifying students' understanding of just how that is done. As configured, the activity is restricted to the first quadrant (positive x- and y-coordinates).

Key Steps

  • Image

    Students will use the file POINT1 in Cabri Jr to determine which direction the points needs to move in order for the first coordinate, or x-coordinate, to stay the same

  • Image

    Students will use the files POINT3, POINT4, and POINT5 to investigate different scoring situations for the game described in Problem 2.
