## Resource

Summary In this episode of Chalk Dust , Rebecca Birch and Nathaniel Swain are joined by instructional coach and Knowledge for Teachers podcast host Brendan Lee. Together, they step inside a Year 3/4 classroom at Morwell Central Primary School, where Brendan delivers a real-time maths lesson on the commutative property of multiplication. They unpack the anatomy of a high-impact lesson, covering how mistake analysis can build reasoning, why mini whiteboard routines make or break lesson flow, and how classroom culture can be shaped in real time, even with a class you've never met. They explore the role of motivation, including how framing content as a “cheat code” gives students a reason to care, and why explicitly teaching mathematical vocabulary supports fluency and retention. Brendan explains how and when to fade scaffolds, the value of concrete–pictorial–abstract progressions, and how this links to dual coding and cognitive load theory. The episode also teases apart the subtle differences between checks for listening, understanding, and thinking, and offers practical strategies for maximising participation and feedback without overcomplicating the lesson. Whether you’re a primary or secondary teacher, maths specialist or not, this episode highlights just how responsive, structured teaching can lift engagement and understanding.
