Teaching Students About Classification of Industry

Classification of industry is an important topic that should be taught to students as it helps them understand the various types of industries and their functions. The classification of industry can be divided into three categories: primary, secondary, and tertiary. In this article, we will discuss each category and provide examples to help students better understand the concept.

Primary Industry

The primary industry includes activities that involve extracting natural resources directly from the earth. This includes agriculture, mining, fishing, and forestry. These industries are concerned with the extraction of raw materials that are then processed into products that can be used by other industries. For example, the mining industry extracts minerals that are then processed into metals by secondary industries.

Secondary Industry

The secondary industry involves the manufacturing of products from raw materials extracted by primary industries. This sector includes industries that produce goods such as cars, textiles, steel, and electronics. It is often known as the industrial sector due to its focus on mass production. The products produced in this sector are then sold to retailers or wholesalers who sell them to consumers.

Tertiary Industry

The tertiary industry is also known as the service sector and includes industries that provide services to individuals and businesses. This sector includes industries such as healthcare, education, finance, tourism, and hospitality. These industries are concerned with providing services that support other industries or individuals.

Importance of Classification of Industry

The classification of industry is important as it helps us understand the role of different industries in the economy. It also helps policymakers in making decisions as they can understand the impact of different industries on the environment, employment, and economic growth. The classification of industry can also help students choose a career as they can identify the industries that interest them.

Tips for Teaching Classification of Industry

When teaching classification of industry, it is important to use real-world examples to help students better understand the concept. For example, you can use the mining industry to explain the primary sector, the automobile industry to explain the secondary sector, and the healthcare industry to explain the tertiary sector. It is also important to encourage students to ask questions and engage in discussions about the classification of industry.


Teaching students about the classification of industry is important as it helps them develop a better understanding of the economy and the various industries that drive it. The primary, secondary, and tertiary industry classification system provides a useful framework for understanding the different roles that industries play in the economy. By using real-world examples and encouraging discussion, teachers can help students develop a deeper understanding of this topic.
