I am a complete beginner with this and need some help.  I tried a couple games at the Hour of Code website and those were fine.  I went to www.code.org and tried Course 2 (for students who can read) and found the unplugged activity, drawing on graph paper and writing an algorithm for it, difficult.  There didn't seem to be a help screen or explanation of the commands. If you are knowledgeable and available to give me some guidance, I'd appreciate it.
