There are a lot of great reading sites. The following are some that help your child read better while others are just for pleasure.
Starfall Learn to Read is a great fun site to supplement your child’s reading curriculum. There is more if you want to become a member but the free stuff is so great that you don’t need a membership. http://www.starfall.com/
Children’s Storybooks Online is a fun site with different stories to read. The stories are not narrated however. http://www.magickeys.com/books/
Progect Gutenbeg is a website dedicated to free e-books. Enough said. http://www.gutenberg.org/
Ancient Faith Radio is an Orthadox Christian website giving you access to podcasts and a lot more. I am a Christian but I do not associate myself as an Orthadox. The main reason for posting this site is that they have a free audio download for the Chronicles of Narnia. http://ancientfaith.com/
I will rarely recommend a resource that you will have to buy or pay a membership fee. However, when I find one that I truly love I recommend it. Shurley English is such a resource. My daughter thrives on this program. It is fun enough that my son, who is at tactile/kinesthetic learner, will like it too. https://www.shurley.com/
Free Language Stuff website is good. It isn’t the greatest but if you need some extra worksheets for grammar and language it is a good place to go, for free. http://freelanguagestuff.com/
