This article draws on qualitative data from two Spanish-English dual language elementary classrooms to explore how teachers in these classrooms made sense of the everyday practice of bilingualism. Methodologically, this study relied on participant observation, video recording, and semi-structured interviews. Conceptually, this article draws on the notion of "translanguaging" to describe how these teachers and their students moved fluidly across multiple languages and dialects in their everyday interactions. Drawing on "language ideological inquiry", this article illustrates that these teachers' perspectives on translanguaging sometimes echoed ideologies of linguistic purism that emphasize language separation, while also reflecting counterhegemonic ideologies that privilege Spanish and promote bilingualism. Teachers' everyday language use and instructional practices both reflected and contrasted with their stated ideologies. It is argued that a more nuanced understanding of teachers' complex language ideologies can inform efforts to help them embrace translanguaging pedagogies that recognize and build on students' everyday bilingualism.
