here is a great online reading tool available to students through PA Power Library. There are two eBook collections, TrueFlix and BookFlix, as well as a fun database searching tool and a CyberSmarts book collection.

BookFlix is a collection of partnered videos and eBooks. The students watch a video of children's picture books, and then read (or listen to) a nonfiction eBook that partners with that title. TrueFlix is a collection of mostly science and social studies nonfiction ebooks that use videos to introduce some background info, and then the kids can read (or have read to them) various ebooks.
