Lesson Plan: Scarcity, Choice, Scale of Preference, Opportunity Cost

Grade Level: Senior High School (First Year)

Previous Knowledge: - Students should have a basic understanding of economics and the concept of resources. - Students should be familiar with the concept of supply and demand.

Objective: By the end of the lesson, students will be able to: 1. Define and explain the concepts of scarcity, choice, scale of preference, and opportunity cost. 2. Understand the relationship between scarcity, choice, and opportunity cost. 3. Apply the concepts to real-life scenarios and make informed decisions based on opportunity cost.

Teaching Learning Materials: - Whiteboard and markers - Handouts with definitions and examples - Real-life scenarios for group activities - Chart paper and markers for group presentations

Teacher Activities: 1. Begin the lesson by asking students if they have ever experienced a situation where they had to make a choice due to limited resources. Discuss their responses briefly. 2. Introduce the concept of scarcity and explain that it refers to the limited availability of resources compared to unlimited wants and needs. 3. Define choice as the act of selecting one option over another when faced with scarcity. 4. Explain the concept of scale of preference, which refers to the ranking of wants and needs based on their importance to an individual. 5. Discuss the concept of opportunity cost, which is the value of the next best alternative that is given up when making a choice. 6. Provide examples and scenarios to illustrate each concept, allowing students to actively participate in the discussion. 7. Distribute handouts with definitions and examples for students to refer to during the lesson. 8. Divide students into small groups and provide each group with a real-life scenario where they have to make a choice. Ask them to identify the scarcity, list their scale of preference, and determine the opportunity cost of their choice. 9. Give each group chart paper and markers to create a visual representation of their scenario, including the concepts of scarcity, choice, scale of preference, and opportunity cost. 10. Ask each group to present their scenario and explain their decision-making process to the class. 11. Facilitate a class discussion on the different scenarios and the concepts applied. Encourage students to ask questions and provide feedback to their peers.

Student Activities: 1. Participate in the class discussion by sharing personal experiences related to scarcity and choice. 2. Take notes during the teacher’s explanation of the concepts. 3. Engage in group activities to apply the concepts to real-life scenarios. 4. Collaborate with group members to create a visual representation of their scenario. 5. Present their scenario and explain their decision-making process to the class. 6. Actively participate in the class discussion by asking questions and providing feedback to their peers.

Assessment: - Observe students’ participation and engagement during class activities and discussions. - Review students’ group presentations and assess their understanding of the concepts. - Assign a short written reflection where students explain a personal experience related to scarcity, choice, and opportunity cost.
