If he is reading beginner books then it isnt too hard to teach the same reading skills using games. Basically at the beginner books level of reading the idea is to increase fluency in the most commonly seem words. Words like the Dolch List (google it) and other sight word lists. Once the fluency is automatic for these words the reading itself becomes more enjoyable and less of a challenge. I would spend some time figureing out the end goal then focus on other ways to achieve it. Mrs Perkins has a great set of printable games for sight word fluency that all my kids loved. Spend your reading time playing these games for a few weeks and then begin a read every day routine. When you go back to every day reading start at a level you think will be easy so that the success is garenteed. Then creep up until you hit some resistence. Its OK if not every book they read is hard work for them. Its a delicate balance.
I also think those Dr Zuess interactive Ipad apps are a good idea. there are pleny to choose from and they are even more interesting than a book.
Continue to read to your child to make sure the opinion of books stays positive over all.
