very school subject has its distinctive ways of engaging with knowledge and its own disciplinary literacy practices of thinking, speaking, reading, and writing. Bi/multilingual learners, at all levels of English proficiency, have the potential to make important contributions to learning in all subjects as they engage with their peers in disciplinary literacy practices. They bring cultural knowledge and experience that can enrich classroom conversations and extend the worldviews and perspectives of other students. Supporting bi/multilingual students to participate fully in gradelevel activities is also the most important thing educators can do to help them make progress in achieving grade-level standards and developing disciplinary language and literacy (National Academies of Sciences, Engineering, and Medicine, 2018).An important way to support students' participation, even as newly arrived students, is to create a translanguaging classroom (García, Johnson, & Seltzer, 2017). In the translanguaging classroom, students are invited and encouraged to draw on all of their meaning-making resources: home/community language and English, as well as gestures, visuals, and any other means to share meaning, enact their identities, and participate in authentic ways. This recognizes that newly arrived bi/multilingual students come to classrooms as fully developed learners and affirms their home/community linguistic and cultural identities, while also acknowledging that those identities are dynamic and evolving in their new context. Translanguaging supports students' agency in making choices about how they learn and enables them to share their perspectives with others, using their home/ community language(s), cultural practices, and previous learning as resources for engaging in new practices in subject matter classrooms.
