Points & Lines & Slopes (Oh My!)

Activity Overview

Students are introduced to key concepts of the Cartesian plane by moving a point and investigating its coordinates in different quadrants and on the axes.

Key Steps

  • Image

    Students place and label points P and Q anywhere in the coordinate system. Then, they label the coordinates of each point.

  • Image

    Next, students point P to the x-axis and point Q to the y axis.

  • Image

    Students use the Perpendicular tool to construct perpendiculars through point P to each axis.

    They then measure the length of each segment using the Length tool from the Measurement menu.
