Activity Objectives

Students will write transformation rules.

Students will perform the given transformation of their tattoo designs on the coordinate plane.

Guiding Questions
  1. How do you write a transformation rule using words?  Using notation?
  2. How can the tattoo design be transformed to meet specific instructions?
Unit Academic Standards 


G-CO.2: Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).

G-CO.5:  Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another. 

Activity Procedures

Lesson 2, Activity 4:

Key Vocabulary

Translation (slide) Rules

  • Horizontal H(x, y) = (x + h, y)
  • Vertical V(x, y) = (x, y +v)

Reflection (flip) Rules             

  • Across x-axis T(x, y) = (x, –y)
  • Across y-axis T(x, y) = (–x, y)

Rotation (turn) Rules               

  • 90° about the origin R(x, y) = (–y, x)
  • 180° about the origin R(x, y) = (–x, –y)

Days 1 & 2

I. Warm-up (Hand out or read to the students.  Students respond in their binders.)

Now that your apprentice has duplicated your tattoo design, you have revised your design to correct any errors, and you have refined it to make it better…it is ready for application!  Suppose you have a potential client who desires your tattoo. The potential customer loves the design, and specifies where he/she would like it applied. The customer leaves and says he/she will be back next week.  However, there is an issue—when the client returns, he/she has decided to change the original location desired for the tattoo.  So, you will have to TRANSFORM the original tattoo design in order to satisfy the client.  How will you do it?

II. Classwork: Transform Your Tattoo worksheet

Students will work in groups based on the transformation assigned to them by the teacher.  Teacher will hand out cards to designate the transformation that must be performed.

III. Homework:

Additional transformation practice as needed.

Formative Assessments

Transform Your Tattoo worksheet


It may be helpful for some students to number their coordinates before listing the new ones, so the same number corresponds to both the preimage and image points.

The activity may be modified so that only a part of the design has to be transformed, as opposed to the entire design.
