Classification

In mathematics, classification is a method of sorting objects that have certain properties in common. For example, we classify 3 and 5 under odd numbers because they cannot be completely divided by 2. Here, numbers that cannot be divided by 2 are grouped as odd numbers.

Classification involves grouping data based on its shared properties. When classifying data, we look for shared features such as color, structure, or form.

For example, grouping ruled books together as one group and unruled books as another. 
On the other hand, sorting is a method of arranging things in order, but it does not require grouping based on shared features.

Classification depends on different parameters. Here, we will now discuss a few such classifications:

Classification Based on Shape: We classify objects into different groups based on their structure or shape.

For example, balls, oranges, and globes are classified as spherical objects.

Classification of Objects by Size: Objects can be grouped based on size or shape. This type of classification enables us to compare different objects based on how wide, tall, or long they are.

For example, clothing stores classify dresses as small, medium, large, etc.

Classification of Objects by Color: As we have learned, classification helps us compare and organize objects. One of the easiest ways to do this is by grouping objects based on their color. Items with the same color are grouped together. This classification even applies to a variety of objects, like animals, things, or birds, based on their common color.

For example, in flower shops flowers are arranged based on the colors 

Classification of Objects by Quantity: A given set of objects can be sorted into different categories based on the total number of items present in each set.

For example, groups of 2, 4, 8 cups arranged by numbers.

Classification of Numbers: Numbers can be grouped based on their shared features. Here, you’ll learn how they are classified:

• Whole numbers: Whole numbers include 0 and all positive numbers.
  For example: 0, 1, 2, 3, 4,…

• Natural numbers: Natural numbers include all positive counting numbers.
  For example: 1, 2, 3, 4, 5,…

• Integers:  Integers include negative numbers, zero, and positive numbers.
  For example: ..., –2, –1, 0, 1, 2, …

• Positive integers: Positive integers consist of only positive numbers such as 1, 2, 3,...

• Negative integers: Negative integers are always less than zero, such as –1, –2, –3,...

Learn how to classify objects, numbers, and ideas effectively helps students to identify key features, organize items, and understand relationships for better learning. Here, are a few tips and tricks to understand classification. 
 

• Before classifying, understand what classification means, whether grouping objects or items based on common characteristics or features.
   
• Look for defining features like size, shape, color, type, or function. For example, animals can be classified by habitat, diet, or body structure.
   
• Use charts, tables, or diagrams to organize items visually. This helps in comparing and understanding relationships between groups.
   
• When classifying, check for similarities and differences between groups to improve classification skills.
   
• Apply classification to everyday items like fruits, clothes, books, or vehicles. Visual examples make the concept easier to understand and remember.
   

Classification helps organize objects or information based on shared characteristics, making them easier to identify, use, and manage. Some applications of classifications are: 

• In libraries, arranging books by categories such as genre, author, or subject helps readers to quickly identify the book they need.

• In clothing stores, dresses are sorted by size and type, helping customers to select the right items. 

• In waste management, the waste is classified as biodegradable and non-biodegradable to ensure proper recycling, disposal, and environmental protection

• Vehicles are classified by type and size so that traffic rules, parking, and road planning can be effectively applied. 

• In supermarkets, groceries are arranged according to their type, like fruits, vegetables, dairy, or frozen products. It helps shoppers to find the items quickly.
