Middle Grades Math: Transforming Fish
by Texas Instruments

Published on September 24, 2014

Overview

In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.

Key Steps

  • Image

    Students will list the ordered pairs for the fish on the graph. As students perform repeated operations on the coordinates of each figure, have them think about the more general rules that map coordinates from one figure onto another in translations and dilations.

  • Image

    Students will understand that a figure is congruent to a transformed figure if congruency transformations such as translations are done to the coordinates.
