Consumer education and the differentiation between wants and needs is the focus of the third unit of the second grade Focus on Inner City Social Studies (FICSS) series (see SO 008 271). Activities center around five topics -- sources of income, how we know what to buy, how we develop wants, how we decide what to buy, and how we get more for less. The unit also discusses advertisements, businessmen and manufacturers, making choices, and students as consumers. The unit makes students become aware of the pressures of buying, in the hope of making them intelligent consumers. The format of the unit begins with an introduction; essential source materials to teach the unit; knowledge, skill, and behavioral objectives; and supplementary student and teacher resources. (JR)
