Overview Students take a “van and airplane tour” of the West region of the United States. In the Preview activity, a Geography Challenge introduces students to the West. Then, in a Writing for Understanding activity, students listen to a tour guide and view nine images of places in the West. The tour stops at three sites, where students learn more through interactive experiences that teach key concepts of the chapter. Students then use their notes to write a letter about their excursions in the West. In Reading Further, students create a brochure to promote the Pacific Crest Trail. The letter-writing activity serves as the Processing assignment for the chapter
