I am looking for a website on computational thinking. My plan is to teach computational thinking to the students using the four key techniques (cornerstones) to computational thinking: decomposition - breaking down a complex problem or system into smaller, more manageable parts pattern recognition – looking for similarities among and within problems abstraction – focusing on the important information only, ignoring irrelevant detail algorithms - developing a step-by-step solution to the problem, or the rules to follow to solve the problem Then the plan is to allow the students to play computational activities through games. Previously i used an online site delivered by Kiki http://games.thinkingmyself.com/ However this site is no longer live. I have tried different variations of the site and I am guessing it is no longer live as it is probably outdated and only available as a flash format. Can anyone help with a different computational website that has similar types of game challenges?
