**Activity Procedures**

**Lesson 2, Activity 5**

**Days 1 & 2:**

I. Warm-up (Written on board. Students follow along on their laptops).

Letâ€™s set up some key items in our spreadsheet together:

1. Name the file (Excel Tattoo Transformations)

2. Name Sheet 1 (1^{st} transf)

3. Name Sheet 2 (2^{nd} transf)

4. Title Column A (x)

4. Title Column B (y)

5. Save the file to your thumb drive or desktop

II. Classwork:

Hand out the Using Excel to Transform Your Tattoo worksheet. Students will work in their master artist groups to complete the task. Although students will be using their own design coordinates, they will be grouped according to the transformations they have been assigned. Therefore, they will communicate and collaborate with each other to create their spreadsheets, which will be embedded with mathematical formulas to perform the transformations.

##### Differentiation

If entering all of the coordinates of the tattoo design is overwhelming for students, decreasing the requirement to the first ten coordinates is an option.

Students may compare their formulas with a neighbor before actually typing them in the spreadsheet.
