Ebooks and Audio Books would work well in the school room. The audio especially for the younger children who can not read yet. IT is a good way to show children another type of reading source. There are now so many titles both fiction and nonfiction it would assist the children to access books which can not be found anymore or located at their school or library.
being able to download means you can access a number of items at one item for your class or take it with you when moving around.
