Hour of Code

Challenge yourself during the Hour of Code!
Create an app, game or web page project and share what you have done with your friends and family. This will test your HTML, CSS, JavaScript and Python knowledge.

The Hour of Code is a global movement by Computer Science Education Week and Code.org.

It reaches tens of millions of students in 180+ countries through a one-hour introduction to computer science and computer programming.

Every year we make courses freely available to the public so that they can challenge themselves to create amazing programs, apps and web pages. We love being a part of Code.org's initiative!

There is a wide variety of activities and suitable for a younger audience. Children as young as 5 have completed some of these courses, with adult support (Food Frenzy is a good lesson to start off with).
