These fun and simple scavenger hunts are a great way to introduce or review the Dewey Decimal System. Cut out and place the pictures cards on the corresponding bookshelves. Give students the scavenger hunt sheet and have them look for the picture cards. Students can write the section number, where the card was found, in the box. For younger students, you can leave small stickers at each location. Students can fill their boxes with stickers. Includes two scavenger hunts.
