  • Summer Special: How far can you get from the sea in the UK? And early maths notation
    Aug 26 2025

    This week’s bite-sized summer special takes us from the sun-drenched costas of Spain to the seagull-infested arcades of Whitby, with some fascinating insights into how young children record their maths along the way.

    Jon and Becky swap holiday stories and uncover the surprising maths that follows you everywhere – even when you’re meant to be switching off. From suitcase scales gone wrong (pounds versus kilos, anyone?) to crazy golf “unitising,” estimating watermelons, and the enduring mystery of why the furthest you can get from the sea in the UK is only ...(spoilers!), it turns out that holidays are full of mathematical moments.

    Jon also introduces a new segment: Research in 60 Seconds (ish), sharing a fresh study about how young children represent quantity and order in their early notations – and why we should never dismiss unconventional jottings.

    Expect classic British seaside nostalgia, a dash of self-deprecating humour, and plenty of practical ways you can bring real-world maths (and early maths research) into your classroom.

    If you enjoy the show, please share it with a colleague and leave us a rating or review – it really helps other teachers find us.

  • Summer Special: Leading Maths - Why Subject Leadership Matters More Than Ever
    Aug 19 2025

    In this episode of The Primary Maths Podcast, Jon and Becky celebrate the role of the maths subject leader. Whether you’ve been leading maths for years or have just been handed the responsibility as September looms, this conversation explores the challenges and opportunities of the role.

    Jon shares his own journey of unexpectedly becoming a maths lead during his NQT year, while Becky reflects on her experiences leading maths in a large junior school. Together they consider how subject leaders can shape school culture, raise the profile of maths, and drive meaningful change in teaching and learning.

    This week’s Maths of Life takes us on a journey from Ancient Rome to Renaissance Italy to uncover the origins of percentages, why we use them instead of fractions in shops, and why “25% off” feels like more of a bargain than “a quarter off.”

    Topics covered include:

    • Why percentages became the language of bargains
    • The commutative property of percentages (and why it matters)
    • First steps for new maths leads in September
    • Building a positive maths culture in your school
    • Practical ideas for parental engagement
    • Where to find support, training, and inspiration

    If you’re stepping into maths leadership this year, or simply want to reflect on your own practice, this episode offers encouragement, practical strategies, and a reminder that you are not alone in the role.

  • Summer Special: Making Sense of Time: Why Teaching Time Is Harder Than You Think
    Aug 12 2025

    In this bite-sized summer special of The Primary Maths Podcast, Jon and Becky tackle one of the trickiest topics in primary maths: telling the time. From the quirks of analogue clocks to the ubiquity of digital displays, they explore how our approach to teaching time might need a rethink in light of how children experience the modern world.

    They discuss:

    • Why telling the time is more cognitively demanding than many realise
    • The case for introducing digital time first and why it might make life easier for everyone
    • How language, fractions, and number line concepts all come into play when learning analogue clocks
    • What other education systems (like Singapore and Shanghai) do differently
    • Why developmental readiness matters more than curriculum speed

    Plus, in this week’s Maths of Life, Jon dives into the fascinating history of temperature scales from Celsius and Fahrenheit to Kelvin and why zero means very different things depending on the thermometer you’re looking at.

    Whether you’re teaching EYFS pupils to recognise o’clock, guiding Year 2s through quarter past, or still wrestling with 24-hour conversions yourself, this episode is packed with practical insights and a few laughs along the way.

    Listen now and make your next ‘time’ lesson a little less stressful.

  • How Big Is a Billion? And Can You Plan Around a Scheme Without Losing Yourself?
    Aug 5 2025

    Summer Special #2: Mastery Schemes vs Teacher Subject Knowledge – and the Maths of Big Numbers

    This week, Sally Cole joins Jon as guest co-host while Becky continues her well-earned beach break. Sally is an Education Content Lead at Twinkl, working on digital maths resources including the Twinkl Maths app.

    In this second summer special, Jon and Sally explore two big ideas:

    The Maths of Life

    How big is a billion? Inspired by a question from Jon’s daughter, we unpack the history, scale and meaning of this often misunderstood number. From how long it takes to count to a billion, to what it would look like built out of base ten cubes, this is a place value conversation that starts with curiosity and ends with a cube the size of a school building.

    Main Discussion

    Can teachers follow a scheme and still teach responsively?

    We explore the benefits and challenges of using teaching for mastery schemes in schools, and ask:

    • What do maths schemes of work do well?
    • When might they restrict professional judgement or pedagogical flexibility?
    • How can we make sure that teachers remain confident, responsive and well-supported?

    If you're planning for September, reflecting on your maths curriculum, or thinking about teacher subject knowledge, this is an episode for you.

  • Summer Special: The Surprising History of School Holidays – and a Maths Question Answered
    Jul 29 2025

    This week on The Primary Maths Podcast, we're kicking off a special run of summer episodes with something a little different.

    I’m digging into the history of school summer holidays – where they came from, how they’ve changed, and whether they were really designed so children could help with the harvest. (Spoiler: not quite.) Along the way, I explore the rise of seaside holidays, the Grand Tour, and what steam trains had to do with it all.

    Then, I tackle a great listener question: how do we balance fluency with problem solving in maths? Should one come before the other – or is it more complicated than that? I explain how fluency, reasoning and problem solving each play a distinct role in effective maths teaching, and why they’re best taught in tandem.

    Whether you're listening from a sun lounger or sorting out your September plans, I hope you're having the best time – and that this episode keeps you company.

    In this episode:

    • The surprising origins of the school summer break
    • Why fluency isn’t just about speed
    • The case for teaching problem solving early and often
    • How to connect reasoning, fluency and real-world maths

  • Metacognition in Maths: The Secret To Building Resilient Learners - with Nathan Burns
    Jul 22 2025

    How do we help children become confident, independent mathematical thinkers, not just answer-getters?

    In this episode of the Primary Maths Podcast, Jon Cripwell and Becky Brown explore the surprisingly powerful concept of metacognition and what it looks like in real classrooms, from early years to upper Key Stage 2.

    Jon also explains why a 12-inch pizza is nearly four times the size of a six-inch one, and how that misconception links directly to our work as teachers.

    Later, Jon is joined by Nathan Burns, also known as Mr Metacognition, to discuss:



    • What metacognition really means, beyond just thinking about thinking



    • Why it is not just for older or high-attaining pupils



    • How to model thinking in maths lessons without overwhelming your students



    • Practical ways to build mathematical resilience and reflection into your teaching



    The conversation also covers curriculum pressures, classroom talk, and the small changes that can make a big difference to mathematical understanding.


    A quick note: There was a slight issue with Nathan's sound during the recording, which we have tried to clean up as much as possible. Apologies, and thank you for bearing with it.


    Key takeaways


    • Metacognition is more than a buzzword – it is a powerful tool for learning in maths



    • Modelling your thinking out loud helps pupils develop their own strategies



    • Resilience is built by teaching children what to do when they do not know what to do



    • Metacognitive strategies can be used from the early years upwards



    • Classroom talk and exploration matter just as much as correct answers



    • Relying solely on PowerPoint may limit modelling opportunities



    • Real-world contexts, such as pizza pricing, can help make abstract maths meaningful

  • Kate Frood Taught Maths Every Week as a Headteacher - Here's Why
    Jul 15 2025

    What happens when a headteacher keeps teaching? This week, Jon and Becky speak to Kate Frood OBE – a former headteacher who spent 22 years teaching weekly maths lessons alongside school leadership.

    Kate shares how her “Mrs Frood Maths” lessons became a model for coaching and inclusion, why stealth differentiation works better than labels, and how to reclaim joy and challenge in problem solving.

    Plus, in Maths of Life, Jon investigates why a 1/3 pounder burger failed in 1980s America – and what it teaches us about common fraction misconceptions. Becky takes us into the world of speedcubing, synchronised diving, and complex averages.

    It’s a jam-packed episode with stories, laughs and powerful reflections on leadership, subject knowledge and classroom culture.
