Elementary and secondary school teachers interested in developing a local history unit can adapt this fourth grade program created for three school districts in Cortland County, New York. Material is divided into 13 chapters. Chapter 1 charts the New York fourth grade curriculum by concept and content and outlines specific community study activities integrated into the curriculum. Chapters 2 through 9 contain individual maps and histories of each of the four locales studied in the unit: Cortland County, Cincinnatus, Homer, and McGraw. Chapters 10-13 consist of indexes of local history topics, resource persons, historians, and sites for these four areas. An appendix contains Cortland County Historical Society resources, materials prices, and educational services. (LP)
