In this 9-week unit, students compare and contrast goods and services and discuss economic activities that occur in cities, sorting them into the production of goods or the provision of a service. Students examine how people use money to purchase goods and services. Wants are defined in terms of trade-offs or choices that must be made. Job specialization (manufacturing, transportation, and marketing of goods and services) is an additional focus. The lesson plan discusses the significance of the topic; lists focus questions; features literacy links; and provides information and student activities, dividing the topic into: "Beginning the Topic,""Developing the Topic," and "Culminating the Topic." It suggests assessment activities, offers extended/correlated activities, and lists extensive topic resources. Appended are sample worksheets. (BT)
