Computer Science Unplugged

Computer Science without a computer

CS Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. We originally developed this so that young students could dive head-first into Computer Science, experiencing the kinds of questions and challenges that computer scientists experience, but without having to learn programming first.

The collection was originally intended as a resource for outreach and extension, but with the adoption of computing and computational thinking into many classrooms around the world, it is now widely used for teaching. The material has been used in many contexts outside the classroom as well, including science shows, talks for senior citizens, and special events.
