This collection comes from a set of lessons plans to introduce students to the culture of Puerto Rico by looking at customs and objects - specifically masks - connected to the annual celebration of Carnival. The lessons are split into four levels, covering grades K-2, 3-5, 6-8, and 9-12. They were originally adapted from a set of activities that appeared in Our Story in History: A Puerto Rican Carnival, a website produced by the Smithsonian's National Museum of American History - also shown in a link inside the collection, along with instructions for students to make their own masks. The lessons include objects from the Smithsonian's National Museum of the American Indian in New York, the George Gustav Heye Center, and the Department of Anthropology, National Museum of Natural History.
