# Circle Algorithm Art Unplugged Coding Activity

This circle algorithm art activity introduces basic coding skills by giving kids a set of rules and steps to follow to create unique designs in each circle!

An algorithm is a set of specific steps that you can follow to solve a problem. In programming algorithms are used to create solutions to problems that can be reused, like when sorting or searching for something.

One way to teach your children about algorithms and unplugged coding is to have them create algorithm art drawings.

## Circles & Pi

Pi, or π, is the ratio of the circumference of a circle to the diameter. In case you need a refresher, the circumference of a circle is the distance all the way around and the diameter of a circle is the distance across the middle.

Pi begins 3.1415 and mathematicians have spent thousands of years studying this irrational number. Trillions of digits of Pi have been identified so far!

We love to geek out with Pi activities this time of year and this circle algorithm art is a great way to incorporate Pi with tech + art!

What is Pi?

Pi is the ratio of the circumference of any circle to the diameter of that circle. The approximate value of Pi is 3.14.

Who discovered Pi?

Archimedes of Syracuse was the first person to calculate Pi.

Does Pi ever end?

Pi is an irrational number and has no final digit.

## Circle Algorithm Art Drawing – Follow the Rule

The Rule: Every circle must be unique.

This means that each circle must be different. It doesn’t mean that the same line pattern cannot be reused. It just means that if horizontal lines, for example, are used twice then the colors must be different.

## Circle Algorithm Drawing – Use the Algorithm

Decorate each circle according to the instructions in the algorithm. The circle algorithm for this activity is:

1. Draw lines
2. Use more than 3 lines
3. Use at least 2 colors

This algorithm applies to each circle. To work through the activity, children should follow the complete algorithm before moving on to another circle. Every circle should look different.

## How to Solve the Circle Algorithm Art Activity

Start with the first circle and follow the algorithm listed. There must be more than three lines used in the circle and there must be at least two colors used.

After you have colored all circles, make sure that you have followed the rule and produced 9 different circle designs. You’ll find an example of possible answers for this activity below.

## WHY ARE UNPLUGGED CODING ACTIVITIES IMPORTANT?

Unplugged coding activities are designed to build the foundation of coding. These activities allow kids to participate in kinesthetic opportunities that help them relate the concepts they are learning to their own lives and teach children how to think logically about objects, how to break down large tasks into smaller tasks that are easier to complete, and how to identify errors.

Working hands-on makes coding concepts tangible and unplugged coding activities are ideal for young coders. Unplugged activities are great for classrooms or homes that don’t have access to the internet or a computer and ideal for young students who don’t have experience working with computers.

It’s never too early to start teaching the foundation of coding.

## WHAT IS COMPUTATIONAL THINKING?

Computational thinking can be used to solve problems in almost all areas of our lives and helps kids develop some pretty great life skills that can apply to a variety of situations.

A computational thinker approaches problems with a hands-on approach and playing to solve a problem. They work together with others to reach common goals and persevere when faced with difficult problems.

Computational thinkers find and fix errors in complex problems (debug!) and design solutions for open-ended problems.

We love incorporating books into our activities. Here are some great books about coding to read with your activity!
