Last weekend I had a great time attending #BCME10 @bcmeconference However, I was left with some questions about the emphasis on behaviour in discussions about maths policy and practice, compared with its impact in the classroom. So I've written this: interwovenmaths.com/behaviou…
Why is nobody talking about behaviour?

Why is nobody talking about behaviour?

Behaviour is a factor across maths education's biggest issues: how we teach, who stays in teaching and who gets left behind. So why is nobody talking about it?

📐 Simultaneous Equations: Take Your Teaching Deeper! with @mathsjem Ready to explore simultaneous equations beyond the usual methods and procedures? Join this brand-new workshop from the Topics in Depth series for a closer look at one of the key topics in secondary mathematics. This session will unpack simultaneous equations from multiple perspectives, helping you strengthen your subject knowledge, anticipate pupil difficulties and reflect on how best to teach the topic. 🎯 What will we explore? ✅ Curriculum: Where simultaneous equations fit into the wider maths curriculum. ✅ Misconceptions: Common stumbling blocks and why pupils find them challenging. ✅ Explanations: How to communicate the underlying mathematics clearly and effectively. ✅ Subject knowledge: Deepen your understanding of the topic and its connections. ✅ History: Explore the development of simultaneous equations and the ideas behind them. ✅ Resources: Discover materials and approaches to support effective classroom teaching. Whether you’re looking to refresh your knowledge, refine your explanations or find new ways to approach familiar content, this workshop offers an opportunity to examine simultaneous equations in depth. Come ready to question, reflect and develop your teaching with this new addition to the Topics in Depth series! 🎟️ Book your place: completemaths.com/community #MathsConf42

Looking forward to catching up with people at two upcoming events: BCME is this week: a 2 day conference with a focus on academia/research. #mathsconf42 is a Saturday conference in November with a very different teacher-led vibe, where I’m presenting on simultaneous equations
