I would be using the newspaper. Simply reading a few articles together can help for a number of skills:
Pronunciation by reading out loud. As you listen, circle the words he mispronounced. Then, go over the words and show him how to say them properly.This may lead into a lesson on certain pronunciation topics.
Vocabulary. After reading, have him tell you which words he didn't understand. This leads into a vocabulary exercise.
Reading the newspaper will also help his writing and speaking, as he will see real sentences in use.
I find there is no substitute for real English in context.
