While studying genres with 3rd grade, I used genre passports as a reading incentive program. Kids were able to get a genre "passport" during library class. After we discussed each of 5 genres - fantasy, realistic fiction, historical fiction, mystery, and science fiction - students could read the genre and fill out their passport. On the passport, I asked students for the book title and genre clues - how did they know their book fit into this genre? I added a sticker to their passports as each genre was completed. A full passport equaled a prize from the prize box and their picture on the genre passport bulletin board outside the library.
