Abstract
In the current reform of mathematics classrooms teachers are required to develop discourse communities in which all students have equitable opportunities to engage in productive discourse. The challenge is for teachers to engage students in the mathematics talk across a range of classroom situations. In this paper I address how a teacher used interactional strategies to scaffold participation of her diverse students in small group interactions. I report on the actions the teacher took to shift the patterns of discourse from a disputational form to one in which the students collectively constructed group explanations and
justification.
