This is a site that I’m very excited about. I’ve started dipping my toes in the water of teaching computer science to my students and am really enjoying it. The problem is that sometimes the concepts are too theoretical for my students to grasp. They needs something more hands on and something they can physically interact with to understand. Computer Science Unplugged is the answer to my problem. Here’s how they explain their site: 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. The activities introduce students to Computational Thinking through concepts such as binary numbers, algorithms and data compression, separated from the distractions and technical details of having to use computers. Importantly, no programming is required to engage with these ideas! 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!
