In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates.
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.
Students will understand that a figure is congruent to a transformed figure if congruency transformations such as translations are done to the coordinates.
