To begin, Click the button below, then choose LET'S GO from the "Start from the Basics" course block. The videos will do the instruction. If you have older jr. high students, I can see this being something they could do independently, but otherwise, start as a class.
Click the photo to the right to see the Grade Level sorted full course catalog. There are Hour of Code links as well, but if you are looking for a more complete curriculum, this is a great place to start!
