     Six Ways to Improve Reading Comprehension

     Help your child keep what he reads --- a crucial skill, especially as he gets older and needs to

gain important information from textbooks. 

     Let him read aloud.

     This forces him to go slower, which gives him more time to process what he reads.   1  

     Provide the right kinds of books. 

       2   He should recognize at least 90 percent of the words without any help. Stopping to figure

out a word makes it tough for him to focus on the overall meaning of the story. 

       3   To gain meaning from text, your child needs to read quickly and smoothly- a skill known

as fluency. Rereading familiar, simple books gives your child practice at decoding words quickly,

so he'll become more fluent.

     Talk to the teacher.

     If your child is struggling strongly with comprehension, he may need more help with his reading-for

example, building his vocabulary or practicing phonics skills.

     Supplement class reading.

     If his class is studying a particular theme, look for easy-to-read books or magazines on the topic

. Some previous knowledge will help him get better prepared and make his way through tougher

classroom texts.

     Talk about what he's reading.

     This "talking processing" helps him remember and think through the themes of the book.   4  . For

example:

     Before: "What interests you in this book?"

     During: "   5   . Is it turning out the way you thought it would?"

     After: "Can you summarize the book? What did you like about it?"

A. Reread to build fluency.

B. Plus, he's not only seeing the words, he's hearing them, too.

C. What's going on in the book?

D. Do you know all the characters' names in the story?

E. Make sure your child gets lots of practice of reading books that aren't too hard.

F. He should recognize at least 90 percent of the words without any help.

G. Ask questions before, during, and after a reading session.
