Designed for use with fourth and fifth grade combination classes, this student worktext combines concepts and content from both California and U. S. history courses. Material is arranged into the following seven chapters: Discovery and Exploration; Colonizing a New Land; A New Nation and New Californians; Westward Expansion; Civil War, Reconstruction, and Industrial Growth; a New Century (1900-1950); and Modern Problems. Each chapter includes a student reading that places historical developments in California within the context of national development, reading comprehension questions, and a variety of chart, graph, map, and supplemental activities. Drawings and maps illustrate each chapter. An appendix contains the Preamble to the Constitution, the Bill of Rights, a list of California governors, and a list of U. S. presidents and vice-presidents. (LP)
