How to Teach the Dewey Decimal System Without Boring Your Students
Let’s be honest—explaining the Dewey Decimal System can feel dry if it’s just a lecture. But this essential skill doesn’t have to be boring! With the right hands-on activities, games, and challenges, students can learn how to navigate the library while having fun.
Here’s how to make Dewey exciting, engaging, and unforgettable for your elementary students!
1. Turn Dewey Into a Treasure Hunt 🏴☠️
Transform your library into an adventure zone with a Dewey Decimal scavenger hunt!
Thank you for choosing Detective Booksy’s Research Missions for your students. Inside this Library Scavenger Hunt, you will find:
Complete instructions for printing and using the materials
50 missions with 6 questions in each mission
A log for tracking any missions a participant completes
Printable sticker templates to mark the missions on the log
Printable certificate of completion
Detective Booksy’s Research Missions
Each mission has six tasks for students to complete. Each task will lead the students around the library or classroom to find materials based on the topic, format, or genre of the book. In order to complete the missions, students should be able to find (independently or with assistance):
definitions in a dictionary,
synonyms in a thesaurus,
facts in an almanac,
maps in an atlas,
titles and authors of fiction and nonfiction books,
Dewey Decimal call numbers,
subjects of biographies and nonfiction books,
and more.
NOTE: THIS ITEM IS INCLUDED IN DETECTIVE BOOKSY’S RESEARCH VAULT.
How It Works:
Hide clues in different sections of the library.
Create a map where students must use Dewey numbers to find each clue.
The final clue leads to a “treasure”—a prize, a special book, or a fun library privilege!
💡 Example: “Find a book about planets. Look in the 520s!” 🌍🚀

2. Make It a Team Relay Race 🏃♀️📚
A little competition can make learning more exciting!
Print this mini book, fold it, and put it in your pocket on library day. Have students make one to take home, too! Kids need to know how to use the Dewey Decimal System in order to find nonfiction books in the media center or library.
These are the 10 main classifications in the Dewey Decimal System:
000 Computer science, information & general works
100 Philosophy & psychology
200 Religion
300 Social sciences
400 Language
500 Science
600 Technology
700 Arts & recreation
800 Literature
900 History & geography
Need a Dewey Decimal System guide that students can carry around in the library? This mini book is pocket-sized! Print it, fold it, and carry it with you to help you find what you need according to call number. When folded, you will have an 8-page booklet that lists all of the 10 Dewey Decimal classifications and subclasses.
You are purchasing a printable guide to the Dewey Decimal Classifications. I created this mini book in PowerPoint and saved it as a PDF, so you can seamlessly print it and copy it.
Includes complete printable instructions for cutting and folding the mini book, PLUS links to an instructional video and an instructional Google Slides presentation. So, you have 3 options for how to show students to fold the guide.

How It Works:
Split students into teams.
Call out a Dewey Decimal category (e.g., "Find a book about dinosaurs – 560s!").
One student from each team races to find a book from that section.
First team to bring back the correct book earns a point!
✅ Why It Works: Gets students moving, thinking, and engaged!

I first created this library game a decade ago when I was a media specialist for grades K-5. It was easy to pull out a game card (bookmark) whenever I needed something for students to do. You can also use the bookmarks if you are a classroom teacher to scaffold your Language Arts curriculum, and to help students get started on research projects in elementary.
