Computer Science Unplugged is my find of the week.  It houses a collection of free learning activities that teach Computer Science through innovative games and puzzles that use cards, string, crayons and lots of fun and action.

CS unplugged 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.

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