My Take
I really like its ease of use, and the possibility of creating collaborative books. Finally, the sharing on the net of the books created is fantastic!
How I Use It
I use: Book Creator daily in all my math, French, English, history, science, literature, etc.
Indeed, Book Creator offers the possibility of creating awesome digital books with very many media: text, videos, photos, games, cards, drawings, etc.
It's a lot of fun to use and the pupils are very quickly proud of the result!
