Computer Science Unplugged

Computer Science Unplugged is a series of learning activities that reveals a little-known secret: computer science isn't really about computers at all!
Unplugged teaches principles of computer science such as binary numbers, algorithms and data compression through games and puzzles that use cards, string, crayons and lots of running around.

Unplugged is suitable for people of all ages, from elementary school to university, and from many countries and backgrounds. Unplugged has been used around the world for over fifteen years, in classrooms, science centers, homes, and even for holiday events in a park!

You can download Unplugged activities as individual PDF files from their pages on this site, or download a teachers' version of the collection as a single file.
