I am a very poor esl teacher and can´t afford the books that are available. These or any other free children´s books. I found two Golden Books a while ago, but can´t remember where it was. I appreciate all the help I can get. Thanks again.

Check out the books from a library. You can use a public library or the one in your school. These are free and anyone can get a library card.

Here's some books your students will love.

And this great interactive site gives you animated stories, letting the reader chose words for the narrator to pronounce. Check out the "I'm Reading" section!
