A fun way to practice call number order "Scrabble" style! 2-4 students compete to see who can be the first to build a "shelf" of 7 books in Everybody, Nonfiction or Fiction call number order. Over 100 call numbers in all three categories are included, along with rules for playing the game. Call number squares can be attached to "Scrabble" wood letter tiles, or simply glue them to card stock, laminate for durability, and cut them out. Each player will need a "Scrabble" letter rack, or something similar on which to build their bookshelf.
