## Imagining Pi

##### Sponsored by

#### RECOMMENDED AGE LEVEL

Recommended for ages 5 and up with adult supervision.

#### PROJECT DESCRIPTION

March 14th is International Pi Day! In honor of this mystical symbol—and in tandem with the virtual exhibition, Imagining Data—take a deep dive into the complex, irrational, and beautiful world of pi. Turn this abstract notion into a visible form with a little bit of color coding and a little bit of math!

#### MATERIALS

#### INSTRUCTIONS

- Using a pencil and ruler, make a square graph equal in length and width.
*EXAMPLE*: 5in. x 5in., 6in. x 6in., etc.

- Refer to the resource listed and select a number of digits of pi equal to the number of squares in the graph.
- For example, a 5in. x 5in. graph will contain 25 squares.

- In this case, 25 digits of pi would be necessary.
- A larger number of digits will result in a more challenging project.

- Either on the back of your sheet or on a separate piece of paper, create a key to match each digit from 0-9 to a color of your choice.
*EXAMPLE*: 1=red, 2=brown, 3=orange, etc.*OPTIONAL*: On the same page as the color key, write down the digits of pi you will be using. This might make it easier to remember and keep track of the pattern.

- Choose an order in which to fill the squares.
- This example begins from the top-left corner and moves left-to-right, top-to-bottom.

- Color in each square according to its corresponding color and digit until you have filled your entire graph.
- When the graph has been completely filled, cut off the empty space around it.
- Congratulations, you now have just created a physical representation of pi!

**Visualize beyond:**

- Use a lazy susan or a drafting compass to create a Jill Baroff inspired creation where each digit corresponding color is represented by concentric circles.
- Assign each digit to a different color of yarn and weave a wall tapestry on a homemade loom.
- Artist John Sims quilted an entire series using this concept, demonstrating in just how many ways the process can be interpreted!
