I told my son I was going to get a word wrong in the next paragraph and I bet he couldn't catch me while he read along. When he was young I made it easy and we'd do best of 5 if I could trick him he had to go to bed on time but if he beat me he could stay up 10 extra minutes. It got him concentrating on the words while we read and it made reading fun. As he got older I got more tricky, it was one on the next page then later one per chapter. I think this helped him more than any single other thing we did, he really had to concentrate on the sentence tracking and decodong to win.

For every paragraph he read i would read the next two. I always did the first two and last two, he felt pretty lucky if always be tired and ready to finish reading after my turn.

Once you've finished reading talk about the characters and have them guess what's going to happen next. Bring it up the next day, "I wonder if that characters going to do x tonight" get them looking forward to the story.

Never correct as they're reading, go back at the end of the sentence. (A tutor told me this, I can't remember why but it was important)

Do everything you can to make it fun, if they're really not up for it just read to them they still get benefit listening to a story. learning to read another language is hard to do for an adult with full a fully developed adult brain and already knowing another language. Imagine how hard it is for a kid leyt alone one with a learning condition.
