Integrating concepts of basic citizenship education with community involvement, this experiential curriculum provides a means for developing decision making and critical thinking skills within the existing second grade social studies curriculum. The 10 lessons, translated into Spanish, cover the following concepts: friendly, unfriendly and dependable behaviors; friendship responsibilities; trust; individual, group and public ownership; loaned property; conflict over joint ownership; sharing use and responsibility of co-owned property; taxes; community helpers; public services, jobs and workers; authority; rules; penalties; law; police; crime; and helpful and harmful citizenship behaviors. The lessons aim to: develop the ideas that friendships do not last if people are selfish and inconsiderate, owners of shared property must find ways to share use and responsibility of property, some property is used and owned by everyone in the community, and some people are paid by everyone to provide helpful services for the community; explore personal concepts of responsibility and trust; develop respect for property ownership; investigate the roles of a librarian and a police officer as public authorities; and stimulate the use of public service and discriminate between helpful and harmful citizenship behaviors. Each lesson includes a purpose statement, concepts to be learned, materials needed, student objectives, suggested activities and black and white illustrations. (NQA)
