California Becomes a State

Grade 4 students explore the events that led to California becoming a U.S. state in 1850, including the roles of the Mexican-American War, the Gold Rush, and the Bear Flag Revolt. Using Social Studies Alive! California's Promise, students examine how foreign interest from Russia and increasing American migration transformed California from a sparsely settled territory into a booming region seeking statehood. The lesson introduces key vocabulary such as forty-niner, pioneer, republic, and constitution within the context of California's path from Mexican rule to U.S. membership.
