This Element provides an overview of research focusing on language teaching practices for young multilingual learners in primary classrooms in English-speaking contexts. The term 'young multilingual learner' refers to primary school children, with ages ranging from approximately 5 to 12 years old at various English language proficiency levels. Pedagogy-informed research studies conducted in K-5 classrooms are used to develop research-informed pedagogies for young multilingual learners in primary classrooms. The authors use the notion of culturally sustaining teaching practices to provide examples from pedagogy-informed research studies. The focus on early (K-3) and intermediate (4-5) grades provides a range of illustrations of such practices. The Element concludes with implications for teacher education and the preparation of teachers of young multilingual learners.
