The National Council of Teachers of Mathematics (NCTM 1991, 2000) recommends that students be positioned as sense makers who weigh one another's ideas and judge their mathematical validity. The instructional tool discussed in this article helps students engage in discussions that foster student reasoning, then settle on correct mathematics. The author developed a talk frame as a practical teaching and learning aid that values students' evolving thoughts as teachers guide them toward correct mathematical conclusions. The talk frame displays an organized written record of a discussion. It captures students' rewording of a question addressing a significant topic, their evolving reasoning, and the mathematically valid conclusions. The teacher paraphrases and records student thinking and regularly checks with students to make sure that he/she writes accurate representations. (Contains 12 figures.)
