Google's Computational Thinking Lessons

For those who teach upper middle school and higher math, Google has created a site for you that provides a number of lesson plans on computational thinking.  At first I was excited to see the title but found that much of what is available is above my grade level.  But i thought that it could be useful to some.  It came from an article from the Free Technology for Teachers site.  Check it out to see if it fits your need.
