First and one of the biggest some people are poor and dont have the money to get a computer. There for you can not do work, and my other point that having no contact backs this up. Like this if you send home papers the student can not learn, put it this way there is no teacher they have know idea how do they get help. Some parents don't get the new math they have other methods. So they can not help either. This is a valid point this is like trying to do math when you never learned it.
