Free? Really? Great!
Amazon occasionally has free-to-download Kindle titles for kids. But you have to remember to keep checking! Fortunately, Bethany Winston has created a children's lit blog called "No Twiddle Twaddle" where each day, she posts a list of the newest best free eBooks available for kids. All you need is a kindle app and account and you can read these great suggestions. (Your students can read them on any device that will run a kindle app, but they'll have to do individual downloads.)
