Computer Science in Elementary Schools

In my endless search for what's on the web about how educators should teach technology I came across this interesting page about the importance of teaching Computer Science in elementary schools. CSTA Blog Scroll down on this page to the title  Montessori and CS in K-8    What do you think about this?  Is it important to change / push elementary ed technology by adding a computer science component to K-6 curriculum?  Patrice Gans seems to have a lot of interesting things to say.  Note too her links to Scratch and Scratch Jr.  "There has recently been a lot of discussion about improving computer science education and the need to include the elementary and middle school students in the process. As a K-8 technology teacher, this age group is always on my mind. After attending a recent Scratch Conference at MIT, I am convinced, more than ever, that 21st century computing skills have an important place in even the earliest rungs of the K-8 ladder."
