There are quizes and activities associated with the books. They have some that work on the iPad. And the language section looks really interesting. I showed it to my teenager who is in Spanish and French class, may help him practice. http://www.tumblebooks.com/library/asp/book_details.asp?category=Language&subcategory=Spanish
Enjoy reading in KANSAS. Check your state or local library if you are outside of KS.
