Unit 1 Unit 1: Basic Concepts 1 Unit 1 Unit I [7 days] SECTIONS Basic Concepts 1. Scarcity and Opportunity Costs 2. Production Possibilities 3. Trade and Specialization Enduring understandings Students will take away from this unit the following understandings: 1) All resources (i.e. land, labor, capital, and entrepreneurship) are scarce, forcing societies to make economic decisions. 2) Any economic decision results in an opportunity costs and trade-offs. 3) Production possibilities curves demonstrate efficiency, growth, and marginal costs and benefits. 4) Production and consumption increase when individuals, businesses and governments specialize in what they can produce at the lowest opportunity cost and then trade. Key Vocabulary: need want economics Goods services scarcity Shortage factors of production trade-off opportunity cost marginal benefit marginal cost thinking at the margin production possibilities curve production possibilities frontier Efficiency underutilization cost law of increasing cost export import absolute advantage comparative advantage law of comparative advantage Skills Focus: Students will be able to: • Explain why limited productive resources and unlimited wants result in scarcity, opportunity costs and trade offs for individuals, businesses, and governments. • Define opportunity cost as the next best alternative given up when individuals, businesses and governments confront scarcity by making choices. • Give examples of how rational decision making entails comparing the marginal benefits and the marginal costs of an action. Explain that rational decisions occur when the marginal benefits of an action equal or exceed the marginal costs. • Illustrate by means of a production possibilities curve the trade offs between two options. • Define and distinguish between absolute advantage and comparative advantage. • Explain that most trade takes place because of comparative advantage in the production of goods and services. Prerequisites: SS2E1 The student will explain that because of scarcity, people must make choices and incur opportunity costs. SS3E1 The student will describe the four types of productive resources: SS3E3 The student will give examples of interdependence and trade and will explain how voluntary exchange benefits both parties. 2 Unit 1 SS4E1 The student will use the basic economic concepts of trade, opportunity cost, specialization, voluntary exchange, productivity, and price incentives to illustrate historical events. SS5E1 The student will use the basic economic concepts of trade, opportunity cost, specialization, voluntary exchange, productivity, and price incentives to illustrate historical events. Connections: Mathematics: Production possibilities curves relate well to the concept of graphing points on a plane. Absolute and comparative advantage utilizes the math skill of multiplying and dividing fractions. English: Choices made by characters in books read in English illustrate the concept of opportunity costs. Reading skills acquired in Language Arts are vital to understanding concepts in book. Science: Natural resources as discussed in Biology, Earth system, and Environmental Science classes are a type of productive resource. Marketing: In Marketing Principles, students learn about the types of economic resources and other basic economic principles. Suggested Performance Assessment: Students will create booklets that explain the concepts of productive resources, opportunity costs, marginal costs and benefits, production possibilities, and trade. Booklets will be structured as a welcome booklet for new employees at a fictional company. The welcome booklet will address the listed concepts by explaining the following things about the company: what the company produces or what it could produce (opportunity costs), what resources it uses in production (productive resources), how much of the product it produces and why it produces that amount (marginal costs and benefits), what the company could make if it didn’t make its product (production possibilities), and how the company and its products fits into the global economy (trade and specialization). 3 Unit 1 Unit I Basic Concepts SECTION 1 Scarcity and Opportunity Costs Aim: 1 of 3: How do limited productive resources and unlimited wants results in scarcity? SSEF1A Define scarcity as a basic condition that exists when unlimited wants exceed limited productive resources Key Vocabulary: Need, want, economics, goods, services, scarcity Content Expectation: The student will understand that… • limited productive resources and unlimited wants result in scarcity, opportunity costs and trade offs for individuals, businesses, and governments. Core Text: Prentice Hall, Economics pp 2 – 4 Skills Focus Instructional Strategy: (Warm Up) Ask students to name some of the goods and services that they have brought over the past few days. Make a list on the board as these products on the board. Then ask students to list the choices they made when deciding to buy these products (reasons for the purchases). Next, ask students which of the choices listed might be considered economic choices. Guide students in their responses to help them understand the meaning of the term economics. Other Instructional Suggestions: • (Lecture/Discussion) Discuss with students what they already know about the subject of economics. Suggest that they may be familiar with economic ideas, even if they do not know them as such. • (Power Point Presentation) Chapter 1-Section 1 • (Lesson Plan) Use sample lesson plan “Scarcity” (Unit 1 Supplemental Materials #1) • (Lesson Plan) Use sample lesson plan “Economic Choices”. This lesson emphasizes the concepts of scarcity and choice. People engage in economizing behavior; consciously or tacitly, they weigh the relative benefits and costs of each alternative and try to choose the one that will provide them with the greatest net benefits. This activity helps students to identify alternatives and anticipate their associated costs and benefits; it also requires them to make choices among given alternatives. • (Unit 1 Supplemental Materials #2) • (Wrap Up Question) What basic economic problem do both higher-income nations and lowerincome nations have in common? a. too many unskilled laborers b. lack of capital goods c. too much government d. scarcity of resources The answer is d. • (Lecture Notes) I. What is Economics? • • Economics is the study of how people make choices to satisfy their wants For example: 4 Unit 1 – – You must choose how to spend your time Businesses must choose how many people to hire II. Scarcity and Opportunity Cost • • Scarcity occurs when there are limited quantities of resources to meet unlimited needs or desires Shortages occur when producers will not or cannot offer goods or services at current prices Other Resources: • Source Articles Folder: High-Tech Homework, pp.3-5. • Unit 1 Folder: Careers in Economics, Economist, p.11. • Virtual Economics Disk: Document is Taken From: Capstone: Exemplary Lessons for High School Economics-Teachers Guide.

SSEF1b Define and give examples of productive resources (e.g., land (natural), labor (human), capital (capital goods), entrepreneurship Key Vocabulary: Scarcity, shortage, factors of production Content Expectation: The student will understand that… • limited productive resources and unlimited wants result in scarcity, opportunity costs and trade offs for individuals, businesses, and governments. Core Text: Prentice Hall: Economics, pp. 1 – 6 Skills Focus Instructional Strategy: (Warm up) Ask students to make a list of the items that comes to mind when they hear the word scarce. Have students to brainstorm a list of items that they think might be scarce. This will serve as review of the previous lesson. Other Instructional Suggestions: • (Lecture) Presentation Pro-Chapter 1-Section 1 • (Activity) Students are to create a web diagram that shows how entrepreneurs bring together the factors of production. Tell students to place the word “Entrepreneur” in the central oval and to place various factors of production in the other ovals. A template of the graphic organizer can be found in Chapter 1, Section 1 of the Section Reading Support Transparency System. Students should write a brief description of each factors of production that appears on the graph. • (Independent Study) Students are to create their own business, becoming entrepreneurs. They are to write a small business plan outlining the name of the business, the goods or services that they plan to produce, and their target market. Next students are to make a list of all of the human, capital, and natural resources that will be needed in order to run their business. • (Wrap Up Question) Which of the following is an example of an investment in human capital? a. A company builds a new factory. b. A state puts in a new highway. c. A person goes to college. d. A country builds new schools. The answer is c • (Lecture Notes) The Factors of Productions • • • Land - All natural resources that are used to produce goods and services.

SSEF1c List a variety of strategies for allocating scarce resources. (1d) Define opportunity cost as the next best alternative given up when individuals. Businesses, and governments confront scarcity by making choices Key Vocabulary: Trade-off, opportunity cost Content Expectation: The student will understand that… • opportunity cost is the next best alternative given up when individuals, businesses and governments confront scarcity by making choices. Core Text: Economics: Principles in Action – Chapter 1, Section 2 (pp 8-11) Instructional Suggestions: • (Warm – Up) Identify five appealing vacation destinations. On a decision making grid, fill in the benefits of each destination. Tell students that they can choose just one. Ask volunteers to explain their choices and to describe what they gave up by choosing that vacation over others. Explain that in this section they will learn about trade-offs. • (Lecture) From Presentation Pro – Chapter 1, section 2 – Present guiding questions about how we make decisions. Lecture/discuss bulleted points about the distinction between trade offs and opportunity costs • (Visual) Use transparency 1.2 as a visual aid for types of trade-offs. • (Activity) Using a story everyone should know (a fairy tale, story read for literature, etc.), have students analyze the story to find examples of opportunity costs and trade-offs. In addition, have students create their own short stories (real or imagined) that illustrate opportunity costs and tradeoffs. Have students share stories with classmates and have classmates pick out the opportunity costs and trade-offs in the student-created stories. • (Article) Have students read and summarize article on opportunity costs (Unit 1 Supplemental Materials #3) • (Lecture Notes) Opportunity Cost • • • Does every decision you make involve trade-offs? How can a decision-making grid help you identify the opportunity cost of a decision? How will thinking at the margin affect decisions you make? Tradeoffs and Opportunity Cost 8 • • Unit 1 Trade-offs are all the alternatives that we give up whenever we choose one course of action over others. The most desirable alternative given up as a result of a decision is known as opportunity cost. All individuals and groups of people make decisions that involve trade-offs.

SSEF2a Illustrate by means of a production possibilities curve the trade offs between two options. Key Vocabulary: Marginal benefit, marginal cost, thinking at the margin Content Expectation: The student will understand that… • rational decision making entails comparing the marginal benefits and the marginal costs of an action. • rational decisions occur when the marginal benefits of an action equal or exceed the marginal costs. Core Text: Economics: Principles in Action – Chapter 1, Section 2 (pp 8-11) Instructional Suggestions: • (Warm –Up) List the benefits and costs of one extra hour of study time, two extra hours of time, and three extra hours of study time. Use the student responses to introduce the idea of marginal cost and marginal benefit. • (Lecture) Questions to answer: What is thinking at the margin? Why do we think at the margin? How do we make effective decision at the margin? Use example from warm-up and other similar examples to reinforce the idea. • (Activity) Students come up with posters or transparencies that show the idea of thinking at the margin for a decision of their own choosing. If creating a chart, it should resemble the Marginal benefits chart displayed in the text and the Presentation Pro CD-Rom. If creating an illustration, it should clearly lay out the marginal benefits and costs of each marginal decision. Students should present posters to class. • (Lesson Plan) Use sample lesson plan “Making Choices” (Unit 1 Supplemental Materials #8) • (Lecture Notes) Examples: Decision Making Grid • Economists encourage us to consider the benefits and costs of our decisions. (Use the Karen Decision-making Grid in the textbook page 10 or the Presentation Pro-CD.) Thinking at the Margin • When you decide how much more or less to do, you are thinking at the margin. ( Use example in textbook on page 11) Other Resources: • Presentation Pro CD-Rom Differentiation: • Honors: Create a marginal decision making chart for a decision of your choice. Based on the chart, what option would you choose? What is the opportunity cost of making that decision? 10 Unit 1 • • Remediation: Look at Figure 1.3. Which decision would you make? Why? What is the opportunity cost of that decision? ELL: Have students copy the section headings and write a paragraph summarizing key information under each. Have students work in pairs or groups of three to create five questions generalizing the information and content of the sections. Suggest that the answer to each question involve at least one of the key terms. Have groups exchange questions and write out answers. 11 Unit 1 Unit I Basic Concepts SECTION 2 Production Possibilities Aim: 2 of 2: How does a production possibility curve illustrate the tradeoffs between two production possibilities and show efficiency, growth, and cost? SSEF2B Explain that rational decisions occur when the marginal benefits of an action equal or exceed the marginal costs. Key Vocabulary: Production possibilities curve, production possibilities frontier, trade-off, efficiency, underutilization, cost, law of increasing cost Content Expectation: The student will understand that… • a production possibilities curve illustrates the trade offs between two options Core Text: Economics: Principles in Action, pp 13 - 18 Skills Focus Instructional Strategy: (Warm-up) Have students name two products that a society can produce. Create a Venn diagram of the resources that are needed to produce both products, and the resources that are only needed to produce each separate product. Relate the warm-up to the concept of production possibilities (i.e. because shared resources are needed to produce each product, making more of one product means less resources can be used to make the other product) Other Instructional Suggestions: • (Lecture/Discussion) 1. Explain the concept of a production possibilities curve as a simplified model of the production choices that a society must make due to scarcity. 2. Relate the shape of a PPC to the concept of opportunity cost and marginal cost. 3. Explain why a PPC bows outward due to increasing marginal costs (diagram in book on page 15 explains this concept well). 4. Show how the points on a PPC illustrate efficient production points, the points inside a PPC illustrate inefficient production points (due to underutilization of resources), and the points outside of a PPC illustrate impossible production points unless economic growth occurs. 5. Demonstrate the difference between moving to a different production point on the PPC and increasing total production through economic growth. • (Activity) Worksheet with a blank production possibilities frontier. Have students label the x and y axis with two products of their choosing (different from the products chosen for the warm-up). Complete a Venn diagram for the two products such as the one completed as a warm-up. Explain why the opportunity costs of making one product increases as more of the product is produced (specific to the products chosen). Explain why society might want to produce at one point on the PPC versus at another point. Explain what it would take to move production to a point outside of the PPC (specific example). After students complete the worksheet, take all students through an example solution, using student input and participation to answer all the questions. • (Worksheet) Have students complete worksheet on Production Possibilities Curves (Unit 1 Supplemental Materials #4) 12 Unit 1 • (Lecture Notes) Production possibilities • What is a production possibilities graph? • How do production possibilities graphs show efficiency, growth, and cost? • Why are production possibilities frontiers curved lines? • • Production possibilities curve (graph) A production possibilities graph shows alternative ways that an economy can use its resources. The production possibilities frontier is the line that shows the maximum possible output for that economy. Use examples: fig. 1 & 1.5 pages 14 & 15 Efficiency, growth and cost • Efficiency means using resources in such a way as to maximize the production of goods and services. An economy producing output levels on the production possibilities frontier is operating efficiently. • Growth If more resources become available, or if technology improves, an economy can increase its level of output and grow. When this happens, the entire production possibilities curve “shifts to the right.” • Cost A production possibilities graph shows the cost of producing more of one item. To move from point c to point d on this graph has a cost of 3 million pairs of shoes. (Use example fig. 1.5 page 15) Differentiation: • Honors: Have students research the changes in production that occurred in the United States during World War II (for example, changing from producing automobiles to making military vehicles). Ask them to share their research with the class. Hold a discussion in class about what industries might change, during a war today. • Remediation: Have students make a brief outline of the material under the heading “Efficiency, Growth, and Cost” (pp. 15-17). Each of the three factors should be a major heading with descriptive information below it. • ELL: Have students copy the section headings and write a paragraph summarizing key information under each. Have students work in pairs or groups of three to create five questions generalizing the information and content of the sections. Suggest that the answer to each question involve at least one of the key terms. Have groups exchange questions and write out answers. 13 Unit 1 Unit I Basic Concepts SECTION 3 Trade and Specialization Aim 1 of 2: Why do individuals, business and governments trade goods and services? SSEF3a,b Give examples of how individuals and businesses specialize Explain that both parties gain as a result of voluntary, non-fraudulent exchange. Key Vocabulary: Absolute advantage, comparative advantage, law of comparative advantage, export, import Content Expectation: The student will understand that… • the concepts of absolute and comparative advantage can explain why and how individuals, businesses and governments trade. • U.S. imports and exports have an impact on the U.S. and its trading partners Core Text: Economics: Principles in Action, pp 441-447 Skills Focus Instructional Strategy: (Activity) Student groups of four or five skim over the chapter 17, section on resource distribution. After reading, students then create and perform a three to five minute skit that illustrates how unequal resource distribution affects trade. (This activity is one of the activities provided on p. 61 of Lesson Plan Resource). Other Instructional Suggestions: • (Warm-up) Ask students to list examples of times in which they have traded with other people. Have students volunteer to explain what motivated them to trade with others. Lead them to understand that because resources are not allocated equally, trade is necessary to satisfy wants and needs. This warm-up is suggested on p.441 of the text under bell-ringer. • (Lecture) Use the Presentation Pro CD-Rom ch. 17, section 1 to introduce the focal point of “Why Nation’s Trade?” The Presentation Pro will bring up several key questions to kick off the discussion. Do not go into the absolute and comparative advantage portion of section 1. Absolute and comparative will be included in tomorrow’s lesson. Discuss how unequal distribution of resources leads to trade. Help students understand how this distribution of resources helps trading partners determine which goods and services to produce. The Presentation Pro for this section will help present key concepts, initiate discussion and review section content for this topic. Transparencies 17B-U.S. Trade Partners and 17C-U.S. Exports and Imports are good visuals to use for supporting this lecture. • (Lesson Plan) Use sample lesson plan “Trade” (Unit 1 Supplemental Materials #7) • (Guided Reading) Have student complete guided reading questions and discuss (Unit 1 Supplemental Materials #5) • (Wrap-up) Without trade, what would happen to the economic growth of nations and why? (This question comes from the close and reteach suggestion on p. 441 in the text). • (Lecture Notes) Resource Distribution and Trade (Chart fig. 17.1 page 442) • Each country of the world possesses different types and quantities of land, labor, and capital resources. 14 Unit 1 • By specializing in the production of certain goods and services, nations can use their resources more efficiently. • Specialization and trade can benefit all nations. Imports and Exports of the United States (fig. 17.5 page 446) The United States is the world’s largest exporter. The United States is also the world’s largest importer. The United States’ main trading partners are Canada, Mexico and Japan. Trade and Employment • Workers who lose their jobs due to specialization face three options: – Unemployment: Inability to adapt and find a new job – Relocation: Moving to where current skills meet current jobs – Retraining: Gaining new human capital to meet the demands of specialized labor markets As nations begin to specialize in certain goods, dramatic changes in the nation’s employment patterns also occur. Other Resources: • Presentation Pro CD-Rom • Transparency Resource Package • Text Questions and an activity from the Lesson Plans Resource • Learning Styles Resource Folder • Lesson Plan Resource Folder • The Global Economy folder • Economic Simulations Booklet • Math Practice Booklet Differentiation: • Honors: Ask students to research and write about the roles played by President Millard Fillmore and Commodore Matthew Perry in opening Japanese ports to trade with the United States. Have students answer the following questions in their reports: Why did the United States believe that this trade was vital to its interests? How did Perry convince the reluctant Japanese to honor his respect? Was this trade based on mutual need? • Remediation: Outline the section on pages 441-443 titled “Resource Distribution”. • ELL: Have students copy the section headings and write a paragraph summarizing key information under each. Have students work in pairs or groups of three to create five questions generalizing the information and content of the sections. Suggest that the answer to each question involve at least one of the key terms. Have groups exchange questions and write out answers. 15 Unit 1 Unit I Basic Concepts SECTION 3 Trade and Specialization Aim: 2 of 2: How are the concepts of absolute and comparative advantage used to explain why and how countries trade? SSEIN1 Define and distinguish between absolute advantage and comparative advantage. Explain that most trade takes place because of comparative advantage in the production of a good or service. Key Vocabulary: Absolute advantage, comparative advantage, law of comparative advantage Content Expectation: The student will understand that… • most trade takes place because of comparative advantage in the production of goods and services. • having a comparative advantage means having a lower opportunity cost in the production of a good. Core Text: Economics: Principles in Action pp. 441- 447 Skills Focus Instructional Strategy: (Warm-up) Have students read the section titled “comparative advantage” and then answer the question on bottom page 444, which asks them to restate the law of comparative advantage. Other Instructional Suggestions: • (Discussion/lecture) Discuss the definitions of comparative advantage, absolute advantage and law of comparative advantage. Have students demonstrate comparative and absolute advantage using opportunity cost. • (Activity) Have students do activities demonstrating/calculating comparative and absolute advantage from word problems. Have students apply the concept of comparative advantage to explain why and how countries trade. • (Problem) Have students answer the Comparative Advantage problem (Unit 1 Supplemental Materials #6) • (Lecture Notes) Absolute and Comparative Advantage • A person or nation has an absolute advantage when it can produce a particular good at a lower cost than another person or nation. • Comparative advantage is the ability of one person or nation to produce a good at a lower opportunity cost than that of another person or nation. The law of comparative advantage states that nations are better off when they produce goods and services for which they have a comparative advantage in supplying. Benefits of Trade see Fig. 17.4 page 445. In this example, both Kate and Carlos benefit from specialization. Differentiation: 16 • • • Unit 1 Honors: Create an example of the opportunity costs of production of two goods for two different people. Determine who would have the comparative advantage in producing each good. Remediation: Write the law of comparative advantage. Give an example that illustrates this law. ELL: Have students copy the section headings and write a paragraph summarizing key information under each. Have students work in pairs or groups of three to create five questions generalizing the information and content of the sections. Suggest that the answer to each question involve at least one of the key terms. Have groups exchange questions and write out answers. 17
