This mixed-method study examines the relationship between classroom discussion and student performance in twenty 3rd and 4th grade classrooms in northern California with 50% English language learners (ELLs). Discussions were scored on features including use of multiple approaches for solving problems, students’ opportunities to speak, equitable participation, explanations, and connections between ideas. A linguistically-modified math assessment measured student performance. Quantitative analysis using hierarchical linear modeling (HLM) showed that the discussion features variety of approaches and equitable participation significantly contributed to the explanation of between-class variation in assessment scores, above and beyond that explained by prior mathematics performance and English proficiency. Importantly, mathematical discussion was equally beneficial for students classified as ELLs and those not classified as ELLs. Two classroom vignettes illustrate the different features of discussion and offer insight into ways ELLs contributed to the discussion in different contexts.

This conceptual paper presents a framework for supporting multilingual students’ mathematical discourse through teacher professional development grounded in design-based research (DBR). Drawing on sociocultural learning theory, the Integrated Language and Mathematics Project (ILMP) was co-developed with elementary educators to promote integrated instruction that simultaneously advances students’ mathematical understanding, language development, and cultural identity. The ILMP framework centers around three instructional pillars: attention to language, attention to mathematical thinking, and cultural responsiveness. Through collaborative inquiry cycles, educators engaged as learners, contributors, and designers of practice, iteratively enacting and reflecting on instructional strategies rooted in students’ linguistic and cultural assets. Teachers implemented discussion-rich mathematical tasks, supported by language scaffolds and culturally relevant contexts, to foster students’ mathematical reasoning and communication. This approach was particularly impactful for multilingual learners, whose language use and problem-solving strategies were both valued and elevated. This paper also discusses the opportunities and challenges of DBR and research–practice partnerships, including flexibility in implementation and navigating district-level priorities. Insights underscore the importance of practitioner agency, asset-based pedagogy, and the co-construction of professional learning. The ILMP framework offers a scalable, equity-oriented model for improving integrated language and mathematics instruction in diverse elementary classrooms and beyond.

This article explores how multicultural children’s literature for elementary classrooms can be leveraged to develop students’ mathematical understanding and foster positive math identities, particularly for multilingual learners. By integrating diverse stories into mathematics instruction, teachers can create culturally relevant contexts that invite meaningful problem-solving in tandem with rich mathematical discourse. This article features a classroom vignette in which a third-grade teacher uses Too Many Tamales to engage students in an equal share task, demonstrating how students' cultural experiences enhance their conceptual mathematical understanding. Several pedagogical strategies are highlighted as effective ways to support mathematical reasoning and understanding through authentic mathematical discourse. Drawing from classroom practice and supported by research, the authors advocate for the use of multicultural texts to provide meaningful opportunities for students to connect their lived experiences to mathematical ideas, empowering them to see themselves as capable mathematicians.

While peer-to-peer conversations can be beneficial for children’s linguistic and mathematical development, the specific conditions needed to support optimal conversations remain elusive. As part of a larger project to infuse peer-to-peer interactions into mathematics instruction for multilingual students, 8- to 11-year-old children in the U.S. were videotaped by their teachers interviewing one another about their solution strategies to equal sharing problems. Partner Interviews were analyzed to determine the quality of the interactions between pairs using Barwell’s (2023) definition of negotiating meaning. This study examines the relationships among the quality of student negotiations, accuracy of strategies, similarities between strategies, and grade levels. Findings indicate that the degree to which students negotiated each other’s ideas varied, and the accuracy of students’ solutions was related to the quality of their negotiations. We provide a framework for assessing the quality of the peer-to-peer negotiations as well as concrete examples of the structures and scaffolds used to elicit these conversations.
