Promote reading outside of the classroom by rewarding students with a "Caught Reading Ticket" whenever an adult catches them reading on their own (hallway, cafeteria, bus area, etc). Have student fill out their ticket (name, grade, teacher).
Create a drop off box in a central location for students to drop their tickets in. Each Friday, randomly select a certain number of tickets and award the winners with a prize. I allow my winners to select a book of their choice from my book tub.
