Abstract:	In this report, we examine the noticing of a group of secondary-school mathematics teachers of aspects of the mathematical discourse during the collaborative discussion of a task on teaching angles. Our framework integrates aspects of the mathematical discourse in content-specific teaching that are responsive to students' common challenges in learning angles, as a focus of mathematics teachers' noticing. The data were collected during a one-day workshop. Using hybrid methods of deductive and inductive analysis, we examine what teachers identify, interpret, and decide regarding mathematical vocabulary, mathematical explanations, and graphical examples for teaching angles. A result is that the teachers in the group engaged in noticing mathematical-linguistic explanations with multimodal examples for teaching angles with meaning in dynamic contexts and in relation to non-metric properties.
