Grade 10 Economics: Supply and Demand

Introduction

Imagine why the price of gasoline suddenly increases or why gadgets become cheaper after a few months. These changes are not random—they are influenced by supply and demand, two of the most important concepts in economics. In this lesson, students will explore how these forces interact to determine prices in the market and affect everyday decisions.

Task

Students will analyze a real-life product (e.g., rice, smartphones, or clothing) and create a short presentation or infographic explaining how supply and demand affect its price.

End Product:

A visual presentation (PowerPoint, Canva, or poster) showing:

  • Definition of supply and demand
  • Factors affecting each
  • A real-life example
  • A simple supply and demand graph
Process
  1. Understand the Concepts

    Study the basic meaning of supply and demand and how they interact.
  2. Choose a Product

    Select a common product relevant to daily life.
  3. Research Factors

    Identify factors affecting supply (e.g., cost of production) and demand (e.g., consumer preference).
  4. Analyze the Market

    Explain how these factors affect the price of your chosen product.
  5. Create a Visual Output

    Prepare a presentation or infographic with explanations and a simple graph.
  6. Present Findings

    Share your work with the class.

Resources

  • Online articles on supply and demand (e.g., Investopedia, Khan Academy)
  • YouTube videos explaining supply and demand
  • Textbook (Economics Grade 10)
  • Graphing tools (Excel, Canva, or paper)
Evaluation

Evaluation (Rubric)

Criteria Excellent (4) Good (3) Fair (2) Needs Improvement (1)
Understanding of Concepts Clear and accurate explanation Mostly correct Some errors Limited understanding

Conclusion

In this lesson, students learned how supply and demand influence prices in real life. By analyzing real-world products, they developed a deeper understanding of economic behavior and decision-making. This activity also encouraged critical thinking, collaboration, and practical application of concepts, helping students connect economics to everyday experiences.
