Objectives (5 - 10 minutes)

1. Understanding of Primary, Secondary, and Tertiary Industries: The teacher must ensure that students understand the differences between these three types of industries. This includes identifying the raw materials used, the production process, and the final product.

2. Identification of Practical Examples of Industries: Students should be able to identify real examples of primary, secondary, and tertiary industries. This can be done through case studies, classroom discussions, or individual research.

3. Understanding the Importance of Industries in the Economy: In addition to identifying and classifying industries, students must understand their importance in the economy of a country or region. This includes job creation, contribution to GDP, and impact on economic development.

Secondary Objectives:

• Development of Critical Thinking: By analyzing the characteristics and importance of industries, students will be encouraged to develop critical thinking skills.

• Encouragement of Active Participation: Through practical activities, group discussions, and presentations, students will be encouraged to actively participate in the class, contributing to a better understanding of the topic.

Introduction (10 - 15 minutes)

1. Review of Related Content: The teacher starts the lesson by reviewing key concepts about the economy and production, such as the difference between goods and services, the production chain, and the importance of economic activities for the development of a country or region. This review should be brief and interactive, encouraging students to participate with questions and comments.

2. Problem Situations: Next, the teacher presents two problem situations that will serve as a starting point for the discussion of the topic.

   • The first situation could be: "Imagine you are the mayor of a city undergoing industrialization. You need to decide which types of industries should be encouraged to establish themselves in the region. What factors would you consider in making this decision?"
   • The second situation could be: "Suppose you are a businessman in the commerce sector. How would you assess the importance of primary, secondary, and tertiary industries for your business?"

3. Contextualization: The teacher then contextualizes the importance of the topic, explaining how the classification of industries is fundamental to understanding the functioning of the economy, wealth distribution, and job creation. Real examples from different countries or regions can be used to illustrate how the industrial structure can vary and affect society.

4. Gaining Attention: To arouse students' interest, the teacher can present curiosities or historical facts related to the topic. Some possible examples are:

   • The Industrial Revolution, which marked the transition from an economy based on agriculture and craftsmanship to an industrialized economy, introducing new technologies and production methods.
   • The importance of primary industries for the colonization and exploration of territories, such as the California Gold Rush or rubber exploitation in the Amazon.
   • The transformation of the industrial sector in recent decades, with the growth of service industries and deindustrialization in some regions.

Development (20 - 25 minutes)

1. Activity 1 - Industrial Classification Game:

   • Objective: This activity aims to develop students' ability to identify and classify different types of industries.
   • Description: The teacher divides the class into groups of 4 to 5 students. Each group receives a set of cards, each representing a type of industry (primary, secondary, or tertiary), along with a brief description of the production process and the final product.
   • Step by step:
     1. The teacher must ensure that all students understand the rules of the game. Each group reads the description of a card and decides in which category it fits (primary, secondary, or tertiary).
     2. After all groups have made their choices, the teacher reveals the correct answer. The groups that answer correctly earn points.
     3. The activity continues until all cards have been classified. The group with the most points at the end is the winner.

2. Activity 2 - Creation of a Production Chain:

   • Objective: This activity aims for students to understand the interdependence between different industrial sectors and the importance of the production chain in the economy.
   • Description: The teacher provides each group with a set of cards, each representing a different stage of the production chain (raw material production, manufacturing, distribution, sale, etc.).
   • Step by step:
     1. Students must organize the cards in a logical sequence, representing the transition from one industry to the next in the production chain.
     2. After creating the chain, students should discuss and note the economic implications of each stage, such as job creation, value added to the product, dependence on natural resources, etc.
     3. Finally, each group must present its production chain to the class, explaining their choices and the economic consequences.

3. Activity 3 - Data Analysis:

   • Objective: This activity aims for students to apply the concepts learned in the analysis of real data about the industry.
   • Description: The teacher provides each group with a series of data about the industry of a country or region (for example, the share of each sector in GDP, the contribution to job creation, etc.).
   • Step by step:
     1. Students must analyze the data and identify trends and patterns.
     2. Then, they should discuss and note the possible reasons for these patterns, considering the concepts of primary, secondary, and tertiary industries.
     3. Finally, each group must present their conclusions to the class, highlighting the importance of classifying industries in understanding the economy.

The teacher should circulate around the room during the activities, assisting the groups and clarifying any doubts. At the end of each activity, there should be a discussion moment where students can share their findings and reflections. This will allow the teacher to make the connection between the activities and the theoretical concepts, reinforcing student learning.

Return (10 - 15 minutes)

1. Group Discussion (5 - 7 minutes): The teacher should promote a group discussion with all students to share the solutions or conclusions found by each group during the activities. This is an opportunity for students to learn from each other, see different perspectives, and apply what they have learned in different contexts. The teacher should encourage all students to actively participate in the discussion, asking questions, sharing doubts, and expressing their opinions.

   • Step by step:
     1. The teacher gathers all students and asks each group to briefly share their solutions or conclusions.
     2. The teacher facilitates the discussion by asking questions to deepen students' understanding, highlighting important points, and connecting the groups' contributions with the theoretical concepts.
     3. The teacher can also ask other groups to comment or complement the ideas presented, promoting a collaborative learning environment and respect for different opinions.

2. Connection with Theory (3 - 5 minutes): After the group discussion, the teacher should review the theoretical concepts covered in the lesson and make the connection with the practical activities. This will help students realize the relevance and applicability of the theoretical concepts, as well as reinforce learning.

   • Step by step:
     1. The teacher briefly reviews the main concepts and definitions presented in the lesson.
     2. Then, the teacher highlights how these concepts were applied in the practical activities, reinforcing the importance of classifying industries and understanding the production chain in the analysis and interpretation of economic data.
     3. The teacher can also ask students how they perceived the application of the concepts in practice, encouraging reflection and critical thinking.

3. Final Reflection (2 - 3 minutes): To conclude the lesson, the teacher proposes that students reflect individually on what they have learned. The teacher can ask guiding questions to help students organize their ideas and identify the most important points.

   • Step by step:
     1. The teacher asks students to silently think for a minute about the following questions:
        • What was the most important concept you learned today?
        • What questions have not been answered yet?
     2. After the reflection, the teacher invites some students to share their answers. The teacher should value all answers, even if they differ from expectations, and take the opportunity to clarify doubts or reinforce concepts.

This Return moment is crucial to consolidate learning, stimulate reflection and self-criticism, and identify possible gaps in students' understanding that can be addressed in future lessons.
