Good lesson planning is an important part of effective teaching, but it can be very challenging to plan lessons that focus on working with students’ reasoning In this project, we aimed to sharpen teachers’focus on facilitating students’ mathematical reasoning by making teachers’ mathematical noticing more productive. The key question guiding the inquiry was: How teachers could notice students’reasoning more productively? The project took place across two groups—a lower and an upper secondary group; involving 11 teachers at a Secondary School in Singapore. Guided by Choy’s (2013) framework of productive noticing, we incorporated lesson play into our existing lesson study protocol to plan teachers’ responses to students’ reasoning. More specifically, we applied the ‘Three-point Framework’ to help us focus on key ideas, students’ cognitive difficulties, and how we might support students in their learning of Set Language and Notation (lower secondary) and Solving Trigonometric Equations (upper secondary). Initial findings suggest that teachers began noticing salient mathematical features of students’ thinking during the study. The study has heightened our sensitivity towards students’ thinking and provided opportunities to hone our questioning techniques. In this round table discussion, we hope to seek suggestions to enhance our noticing for future iterations.
