Reading comprehension and fluency go hand in hand.  One program that has worked for many kids I have worked with is listening to a book on tape and reading aloud with it at the same time.  By working with the same book for a short time period the student is able to concentrate more on what they are reading about, instead of just trying to read the words individually.  Plus being able to start and stop the tape by themselves help when they are not sure of a word. 

 

You can do this at home for your child by just making a recording of a book for them.  Start out with books that are easy to read, short in length, and able to be finished in one sitting.  This will help build confidence in your child's reading ability.  Then gradually increase the level of book as they build their vocabulary.  Make sure you are reading in natural phrases and breaks, as well as the punctuation with differences in your voice tone.

 

I hope it helps!
