Using primary source documents, this teaching unit focuses on the problems Chinese immigrants had in the United States during the late 19th century. Each of three lessons presents issues regarding the decision of Chinese immigrants to come to the United States and their subsequent exclusion from and struggles to assimilate into the U.S. society. The unit offers a unit overview, unit context, correlation to National Standards for U.S. History, unit objectives, a lesson plan list, and a historical background of Chinese immigration and the process of exclusion. Lessons are: (1) "Making a Choice"; (2) "Debating Exclusion"; and (3) "Struggling to Survive." Each lesson includes a variety of ideas and approaches for implementation, student resources in the form of primary source documents, handouts, and a bibliography. (MM)
