Today, City Year Milwaukee is participating in Hour of Code to celebrate Computer Science Week. Hour of Code is a one-hour introduction to computer science, designed to expose students to coding through fun and engaging activities. This global movement reaches tens of millions of students in 180+ countries every year… and this year nine City Year Milwaukee schools are participating.  


Computer science is the defining field of the 21st century, yet most young people do not have the chance to experience it. By sharing Hour of Code with Milwaukee Public School students we can help spread the word that computer science is a subject everyone can learn. 

Students participating in Hour of Code will build coding skills through a project called Traveling Circuit. This project consists of students using cups to build pyramids. But, instead of giving building directions using words, students will use codes which stand for specific actions such as "up", "down," and "arrow." 


By engaging students in this activity we hope to teach young people something new and to spark their interest in computer science, even if they are not in front of the computer! 

Below is some vocabulary that our students will become familiar with during this project: 

  • Binary - A notation that utilizes only two options for each selection.  

  • Bit - Short for “Binary Digit.” It is one digit’s location in a binary number.  

  • Code/Coding - Transformation from one representation to another.  

  • Decode - Convert a coded message into something familiar.  

  • Encode - Convert a familiar message into code.
