The Montana Heritage Project was created to teach young people to care about the places in which they live, including both the natural and the cultural environment. The project encourages students and teachers to better appreciate their community by making it the subject of serious study. Students are invited to think deeply and clearly about the world around them as they explore the place they live: its relationship to the natural environment, its connections to national and world events, and the many cultural beliefs and practices that shape its unique character. Several of the activities in Montana: Stories of the Land refer to Montana Heritage Project methods. Teachers may find these heritage project links useful: Teaching the ALERT processes and What is a Learning Expedition?
