What Are Categories?

Categories are groups of words that belong together because they share something in common. Learning about categories helps us organize words and ideas.

Examples:
  • Apples, bananas, and oranges are all in the fruit category.
  • Chairs, tables, and desks are in the furniture category.
Helpful Hint

When you see a list of words, ask yourself: “What do these have in common?” That will help you find the category.

Why Do We Use Categories?

Categories help us organize our thinking. They make it easier to remember words, sort ideas, and talk about groups of things.

Examples:
  • Dog, cat, and rabbit belong to the animal category.
  • Shirt, pants, and jacket belong to the clothing category.
Helpful Hint

Thinking in categories helps us group words together so we can compare, sort, and describe them more clearly.

Different Kinds of Categories

Some categories are about things we see every day, like food or animals. Others are about ideas, like colors, shapes, or places.

Examples:
  • Red, blue, green → color category.
  • Circle, square, triangle → shape category.
  • School, park, store → place category.
Helpful Hint

Categories can be big or small. A big category like “animals” can have smaller categories, such as “farm animals” or “pets.”

Using Categories in Sentences

We can use categories to make our writing and speaking clearer. When we know the category, we can describe things in groups instead of one by one.

Examples:
  • Lions, tigers, and bears are all wild animals.
  • Milk, cheese, and yogurt belong in the dairy foods category.
Helpful Hint

When you write, think about whether words can be grouped. This helps your reader see how they belong together.

Practicing with Categories

Practicing categories makes it easier to learn new words and connect them with what you already know.

Examples:
  • Carrots, potatoes, and peas → vegetables category.
  • Bus, train, and airplane → transportation category.
Helpful Hint

Make lists of words and sort them into categories. This practice helps you remember and understand words better.
