Since I have been working with my son on writing, and it is impossible to separate reading with writing. I have found some great resources of free reading materials for kids.
The first one is Free Kids Books. It offers children’s books for purchase. Some books are free, but all books are available for free in PDF format. You can print out the PDF and put them in binders. The benefit of that is you can have your child draw or write on these pages, and it become the child’s creation too.
Read to Me is a website where kids can listen to books read by the authors. A nice feature is for some books they have lesson plans that provide talking point and activity ideas. It is a great help for parents.
Storyline Online is another site offers free books. It is run by Screen Actors Guild Foundation, all books are read aloud by some very famous actors and actresses. In addition to books, they also offer book related activities, which is always a welcoming feature for the busy parents who have no time to come up fun activity ideas for the kids.
Update: Now I find some more resources, and some are from comments.
Wegivebooks: is another great site for free children’s books. Seems they have a very large selections.
Memetales: not completely free, but when you sign up, you get 15 books for free, and each week you get a new free book. You can read it online, or on your iPhone/iPAD, or Android tablets, including Kindle.
Gutenberg project: it is a site with more than 30,000 free eBooks, either via Kindle or iBook. Although they are not all for kids, but there are a lot kids books, including picture books.
Do you use any online resources for reading? Would mind sharing with everyone?
