Making the Dewey Decimal System Fun: Engaging Ideas to Liven Up Your Library Lessons

Let’s be honest—teaching the Dewey Decimal System isn’t always the most thrilling part of being a school librarian. While it’s essential for helping students navigate nonfiction books and keeping the library organized, it’s not exactly a topic that sparks instant excitement.

Over the years, I’ve experimented with countless ways to teach Dewey – from interactive games to hands-on activities, with mixed results. Some methods became instant hits with my students… and others didn’t make the cut!

In my TpT store, you’ll find a variety of Dewey Decimal resources, including editable PowerPoint and Google slies presentations, engaging bingo games, printable worksheets, and my best-selling Dewey Decimal Task Cards. But today, I want to focus on sharing a few free and fun ideas (minus a few basic supplies) to help you spice up your Dewey Decimal lessons – no extra purchase required.

I’ll be totally transparent—some of these ideas are gems I’ve picked up from Pinterest or seen floating around on teacher forums and social media. I’ve adapted them over time to fit my classroom needs, and I hope they can bring some fresh energy to your library skills lessons too!

1. Dewey Book Scavenger Hunt

Turn your students into Dewey detectives! Create a simple scavenger hunt that requires students to locate books in each of the 10 Dewey categories. You can hand them a list with clues like “Find a book about planets (500s)” or “Find a book about inventions (600s).” This gets students moving and familiar with the layout of your library.

2. Dewey Relay Races

This one’s a student favorite! Write a variety of topics (e.g., dinosaurs, poetry, presidents) on slips of paper. Divide students into teams. One by one, they draw a topic and race to place it in the correct Dewey category bin or poster. You can use labeled folders, baskets, or signs for each of the 10 main categories.

Or you can try a more advanced version. Create a set of index cards with different Dewey Decimal call numbers written on them. Divide your class into small teams and have each team line up. Hand the first student in each line a card with a call number.

When you say “Go!”, those students race to the shelves to find a book that matches their assigned call number. Once they locate the correct book, they race back and tag the next person in line, who then repeats the process with a new call number.

Continue the relay until everyone has had a turn or until time runs out.

Tip: If you’re verifying each book for accuracy, consider setting aside a few minutes at the end of the activity for students to help re-shelve the books and tidy up the library. It’s a great way to teach responsibility and keep your space organized!

3. Stack & Sort: A Hands-On Dewey Building Challenge

This interactive activity is a student favorite—and all you need are some building blocks! (Duplo blocks work especially well due to their size, but any kind will do.)

Tape a small label onto each block featuring a book title, subject, or even a Dewey call number. Then, challenge your students to “stack and sort” the blocks by grouping together those that belong in the same Dewey Decimal category.

For an extra level of difficulty, use full call numbers and have students practice putting them in correct numerical order -right down to the second or third decimal point!

It’s a fantastic way to bring a tactile, visual element to Dewey Decimal practice—perfect for kinesthetic learners.

4. Popcorn Dewey

This hands-on sorting activity is perfect for a library center or small group rotation.

Start by printing the popcorn bag template. On each bag label, write (or type) the Dewey Decimal category you want students to review. Then, print and cut out the popcorn pieces. On each popcorn piece, write a book title that fits into one of the categories.

Students will “sort the snacks” by placing each popcorn piece into the correct Dewey bag. It’s a simple and engaging way to reinforce category recognition!

You can also adapt this activity for genre sorting – just label the bags with different genres and have students group titles accordingly.

To make prep even easier, I’ve included an editable PowerPoint template in my free resource library. Just type in your titles and print – available in both color and black-and-white versions to suit your printing needs. Click here to access the resource library.

5. Dewey Ring Toss: A Movement-Based Review Game

Borrow cones from your P.E. teacher or grab an inexpensive set from the Dollar Store or Oriental Trading. Label each cone with one of the 10 Dewey Decimal categories and set them up in a row or scattered formation.

Students take turns tossing a ring toward the cones. Whichever cone their ring lands on, they must name a book title or subject that fits into that Dewey category. It’s a great way to get students moving while reinforcing their understanding of nonfiction organization.

6. Pictionary and Charades

Use Dewey topics for a quick and silly review game. Students take turns drawing or acting out a topic while their teammates guess both the subject and its Dewey category. Laughter guaranteed!

7. Create a Dewey Decimal Mural

Make the Dewey System visual! Assign each group a Dewey category and have them illustrate examples of what belongs there. Put the finished posters together to create a colorful class mural or bulletin board that doubles as a reference tool.

Final Thoughts

You don’t need a big budget or a complicated lesson plan to make the Dewey Decimal System engaging. With a little creativity (and a few borrowed ideas from fellow educators), you can turn a dry subject into one your students actually look forward to.
