How I Use It
I used codeacademy as an adult and for kids who are ready to go the extra mile, especially after #hourofcode, it is tremendous. It is completely user paced and even those that seem disengaged on other things love codeacademy because it is 100% about acquiring the skills needed to be creative.
I love codeacademy and have even recommended it to my own personal children. I don't think that it has to be specifically used in a lesson but I think that every child and parent who is interested in coding should be not only aware but active in this environment. It should always be an option for extended learning.
