Classification facts for kids
Classification is like sorting things into groups based on what they have in common. Imagine sorting your toys: all your LEGOs go in one box, and all your action figures go in another. That's classification! It helps us understand the world better by organizing information. We use classification in many parts of our lives, from how libraries arrange books to how scientists study animals.

What is Classification?
Classification is the process of arranging things into categories or groups. We do this based on shared features or rules. For example, you might classify your school subjects into "math," "science," and "arts." This makes it easier to find what you need and to learn about different topics.
Why Do We Classify Things?
People classify things for many reasons. It helps us to:
- Organize information: Like a library sorting books by topic.
- Understand relationships: Seeing how different animals are related.
- Make decisions: Knowing what type of movie you want to watch.
- Solve problems: Grouping similar problems to find common solutions.
Types of Classification
There are many ways we classify things in different areas of life.
Biological Classification
Biological classification is how scientists group living things. This system helps us understand how different plants, animals, fungi, and other organisms are related. The main groups, from largest to smallest, are:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
For example, humans belong to the Animal Kingdom, the Mammal Class, and the Homo sapiens species. This system was largely developed by a scientist named Carl Linnaeus.
Library Classification
Libraries use classification systems to organize their books and other materials. This helps you find the books you are looking for quickly. Two common systems are:
- Dewey Decimal Classification: This system uses numbers to group books by subject. For example, all books about history might start with a certain number.
- Library of Congress Classification: This system uses letters and numbers and is often found in larger academic libraries.
Both systems help librarians place books in a logical order on the shelves.
Film Classification
Film classification, also known as film ratings, tells you if a movie is suitable for certain age groups. These ratings help parents decide what movies their children can watch. For example, a movie might be rated "PG" (Parental Guidance Suggested) or "PG-13" (Parents Strongly Cautioned for ages under 13). These ratings are given based on the movie's content, like its language or themes.
Security Classification
Security classification is about keeping information safe. Governments and organizations use this to protect important secrets. Information is given different levels of classification, like "Confidential," "Secret," or "Top Secret." This means only people with the right permission can see or use that information. It helps protect national security and other sensitive data.
Classification in Literature
In literature, classification can mean grouping different types of stories or books. For example, books can be classified by:
- Genre: Such as fantasy, science fiction, mystery, or historical fiction.
- Target audience: Like children's books, young adult novels, or adult fiction.
- Form: Such as poetry, plays, or novels.
This helps readers find books they will enjoy and helps writers understand different styles.
