This is a detailed introductory powerpoint that explains some of the causes for documented and undocumented immigration of Latin Americans to the United States. The powerpoint is fully in Spanish and includes 3 full lessons and 70 slides. It delves into the causes of immigration going back to colonialism, neocolonialism (with four main examples explored including an example in Chile, Nicaragua, Mexico, and Guatemala), and the dependency theory. The powerpoint also introduces the idea of social hierarchy which existed during colonial times and asks students to discuss whether or not they believe a social hierarchy still exists today. This powerpoint is an excellent introduction for a heritage speakers/native speakers class or an AP Spanish class to a political debate that many of our students can relate to or have even experienced on a personal level. It has clear definitions of key terms, questions for discussion in class, warm ups and exit tickets, maps to clarify geography, and detailed explanations with visuals throughout. It provides students with the historical background needed to understand the current political and social context. It also has students draw their own conclusions and explain their opinions using either historical evidence or evidence from their own life.
