This is a fun site for children to publish their own writing and actually have a book in their hand. Students can write digital books, keep them on a "bookshelf", and parents can log in to purchase their favorites to keep forever. I also like the worksheet feature that allows children to write down their ideas according to a template and then transfer it to the book.
I would also use this to create projects for parents for Mother's Day, etc. It allows you to upload your own photos or use a gallery of clip art.
