Reading is important. Kids won't be into reading when they are having trouble with reading so pick out some really simple books, but also pick out books that are a bit harder and read them to him. Some parents point out the words while reading. You can also take turns reading sentences. When he comes to a harder, longer word break it down for him by covering half the word and sounding out the syllables. There are also books that have no words, just pictures so you can make up the story according to how you interpret the illustrations. It can be something different every time.
