# Activity 3

 Activity Title:  Transformations Unit Title:  Tattoo Transformations Estimated Duration:  1 Day Setting:  Classroom Materials: Transformations Practice worksheet Graph paper desmos.com (online graphing website) Author:  Lakisha Edmondson Date:  July 2015
##### Activity Objectives

Students will transform figures on the coordinate plane.

Students will write transformation rules using appropriate notation.

##### Guiding Questions
1. How do you write a rule to perform a given transformation (translation, reflection, rotation, dilation) on an ordered pair (x, y)?
2. Do rigid transformations result in a change in size or shape?  Which transformations do?
3. How can a single rule be written to perform multiple transformations?

CCSS:

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 3:

I. Warm-up (Pair-Share)

Complete exercises #1-4 on the Transformations Practice worksheet.  Compare answers with your partner.  Class will discuss correct answers.

II. Classwork:

Students may work with a partner to complete the Transformations Practice worksheet.  As students are working, circulate the room to assist as needed.  Also advise students to think of ways that their tattoo design may be transformedâ€”what would it look like if it was translated, reflected, rotated, or dilated?

III. Homework:

Assign textbook exercises as additional practice.
