Smithsonian: National Museum of The American Indian (Classroom Lessons)
The museum provides a variety of materials for use in the classroom. All have been developed by the museum's education staff in collaboration with Native community members. These materials offer rich Native perspectives on the history and contemporary life of many different Native tribes. Although these resources are grouped by category, they often address multiple themes.
