Lesson planning is a critical aspect of teachers’ planning for instruction. Research has shown that a mathematically robust lesson is one that has mathematics content that is focused and coherent, the cognitive demand of tasks students engage with is appropriate, and students have agency, authority and identity as learners. This study proposes a planning tool, for a lesson or sequences of lessons, that focuses on the core of mathematically robust lessons, i.e., the mathematics (content), tasks and discourse. The tool was found to facilitate the development of teachers, both novices and experts.
