My DS also has this problem a little, but it seemed to be somewhat related to scanning ahead while reading. How does he do with reading aloud in terms of speed and intonation? DS reads aloud very fast and with beautiful intonation, but will have to go back and repeat bits because he's scanning forward too much. I had to tell him to read aloud more slowly. It helps. However, he still skips an occasional line or word. He is 6.5.
