Would you rather teach children captivated by books? Children like the ones mentioned here who will read four or eight chapter books in a day, or children turned off by staid, dull, even boring books?
Kids love chapter books where there's time to tell an actual story. They love series where the characters can be developed and plots can build from book to book. Kids love these books, and I'm of the view that a love of reading is one of the most important things to encourage a quality education.
Do, however, feel free to mention any other book series that combine an imaginative and captivating storyline with good sentence structure and correct grammar. I'll be happy to add them to the bookshelf too.
