Don't practice TOO much. Open the Door to Reading. Decorate your classroom door as a book. Take time to vote. Build a trivia contest around students' favorite books and book characters.
Classes compete to win donated books for their classrooms.
Each class gets a BIG bingo card drawn on poster paper. Each teacher has a master list of possible authors and titles. From this list, each class selects 24 choices and writes each one in one of their game card squares. Graph your guests' favorite books. Keep a guest register at the front door of the school.
