Here is a quick Scavenger Hunt for your library students that will get them up and moving. They should be able to complete this task without an OPAC system (I am currently helping in a small K-8 library that still uses the old school library cards in books to track who has what item). Students are asked to find a variety of books (sports, Civil War, mystery, and books by certain authors. They write down the title and move on to the next question.
Also included, is a "Pick a Good Book" poster. Along with the Scavenger Hunt, I like to review strategies for picking out a good book.
