Introduce students to some great mystery books AND have them use their reading comprehension and library skills in this card matching activity. This set of 24 books/cards are to be cut apart and mixed up. Place them face up on a table and have students work together to match the title and author to its summary and call number. Cards are self-checking; colors and halves will fit together if matched correctly. When they have all the Mystery Match-Ups completed, encourage students to find the mysteries that appeal to them, then look for them in your library catalog or on your library shelves. Great independent center activity!
