Res. Math. Educ. 43, No. 2, 182-222 (2012).} \itemab Summary: A case study examines a 5th-grade teacher's orchestration of discourse and interaction to create opportunities for English language learners to participate in the repair of mathematical errors during a unit on finding the area of geometric shapes. The findings detail how the teacher used gestures in grounding her questioning, revoicing students' strategies, and narrating the meaning of geometric features.
