Set amidst an increasingly tense discourse about immigration and substantial pressures on educators, this study examines a three-week fourth-grade social studies unit as taught to a class with a large number of English learners located in a low-income school in the Pacific Northwest. Using ethnographic and sociolinguistic perspectives, we provide evidence of how the teacher leverages a wide array of instructional strategies and scaffolds to build language skills and content knowledge within a fast-paced unit on 19th-century Westward Migration. Embedded within such instruction is the construction of narratives that highlight regional examples of a linguistic and ethnically diverse community and that connect immigration trends on a global scale to local history. These strategies and narratives are then used in a summative lesson about immigration that affirms students' family stories as part of the U.S. history still being written.
