Computer Science... without a Computer!
Free activities for classroom or home
Computer Science 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.
The activities introduce students to underlying concepts such as binary numbers, algorithms and data compression, separated from the distractions and technical details we usually see with computers.
Computer Science Unplugged is suitable for people of all ages, from elementary school to seniors, and from many countries and backgrounds. CS Unplugged has been used around the world for over fifteen years, in classrooms, science centers, homes, and even for holiday events in a park!
The best resource we know for popularizing the mathematics behind computing is in the book Computer Science Unplugged! by Tim Bell, Ian Witten and Mike Fellows. Unplugged! has been translated into over ten languages, including Chinese, Korean, Spanish.
Google has sponsored videos and additional material to make the book useful for teachers and workshop leaders.
Unplugged! is available by download over the internet at Computer Science Unplugged!
