I have worked at an independant children's bookstore for over a decade and have worked with hundreds of reluctant readers, from elementary school through high school as well as leading seminars for teachers.
It is early days yet. DO NOT PUSH IT! Right now you don't need your daughter to be a fluent reader- you need her to WANT to read and to learn that reading is FUN so she can learn to LOVE it. In all of my experience that one thing is the key to getting any kid to read well and read on their own.
I have worked with troubled kids, kids with learning disabilities and some kids who were good students, but just didn't enjoy reading and the one common factor is always finding what they are really interested in and what they like.
I am going to tell you the best thing you can do to get your child to like reading, and it isn't making her read books she doesn't want to read or trying to make her sound out words she doesn't want to sound out. It is SO SIMPLE some parents refuse to believe it, but it is true:
Read out loud with your child. Every day, at least half an hour a day. That is the number one, most important thing I know to get your daughter to become a life-long reader.
I recommend the Rosemary Wells book 'Read To Your Bunny' . It is a short, simple little book with charming pictures and it was one of the first books my son could read out loud on his own after having it read to him over and over.
Also, take her to the library and let HER pick out the books. If you are reading something together that she has chosen, she is much more likely to be interested in it.
Just set aside reading time with mommy or daddy every night or afternoon and go from there. My son is in the 4th grade now and reading at a high school level and is in gifted classes. However, when he began to read, he was not really an early reader- he was right along with all the other kindergarteners and first graders and we just kept reading out loud to him all the time.
In 2nd grade it just 'clicked' for him and he started to devour books and read on his own all the time. Now I know he will be a highly proficient reader who loves to read his entire life.
Don't waste you money on fancy gimmicks or systems and above all DON'T WORRY AND DON'T PUSH IT! I have seen so many kids get turned off of reading by parents who mean well, but push too hard for fluency and comprehension too early. It will come, but only if they learn to love to read and want to pick up the books on their own.
Good luck and just remember: Read out loud!
