Differentiation with the iPad - ESL

I have a student who is a native of China and has limited English.  He can be quite shy and doesn't like speaking in class.  He feels pretty unsure of himself.  I have handed him my iPad to look up things he may be confused about like vocabularly, slang, and American references.    I have downloaded a couple of apps that I hope will be useful to him.  The tool aids his reading comprehension by providing over 25 graphic organizers.

Another app that I plan to use is "Daily Grammar".  This app will allow my ESL student to practice basic English grammar and as his skills build, the exercises will become more challenging.
