Wow. I really like what you're doing! I think it's great that you are providing that tool not only for the students but for the parents as well. I don't know how many times when I was a student my parents would look at what I was doing and have no idea what was going on. Fortunately I didn't need much help, but this is a great tool for students who need help whose parents have been out of school too long to remember how to do it!
