I learned about code.org in 5th grade in a coding club after school on Thursdays. I also learned about scratch.mit.edu in 4th grade. Anyways, code.org really teached us how to code, do some art, repeat 1 single command, and I really liked that when you completed one of those mini-levels (I forgot what they are called) You had the opportunity to see the lines of code that you created! Basicly, code.org is a really fun tutorial on how to learn to write lines of code.
