Dyscalculia Explained: The Difficulty Affecting 6% of Pupils

In this episode of The Primary Maths Podcast, Jon is joined by Cat Eadle from The Dyscalculia Network and Baroness Deborah Bull to explore one of the most overlooked areas in maths education: dyscalculia. Dyscalculia affects around 6% of learners, yet many teachers will go through their entire career without hearing it mentioned in training. So what is it? How does it present in the classroom? And what can we do to better support the pupils who are struggling to make sense of number? Together, Jon, Cat and Deborah unpack what dyscalculia is and what it isn’t, including the difference between general difficulty in maths and a specific learning difficulty. They explore why dyscalculia has historically received far less attention than dyslexia, despite similar prevalence, and how cultural attitudes towards maths may be part of the problem. The conversation moves into the classroom, where Cat shares practical insights into what teachers might notice, from persistent counting in ones to difficulties with number sense, time and memory. The discussion also explores the role of maths anxiety, the importance of early identification, and why some pupils may appear to understand in the moment but struggle to retain learning over time. Jon and his guests also reflect on the wider system, including teacher training, curriculum pressures and the need for greater awareness at policy level. Baroness Bull shares her work in the House of Lords to raise the profile of dyscalculia, including calls for improved recognition, early screening and increased support for schools. This episode is a powerful reminder that for some pupils, maths is not just difficult, it can feel inaccessible. With greater awareness and the right support, that can change.

AfterMaths: From Apollo to Artemis - The Maths Behind Space Travel

In this episode of The Primary Maths Podcast, Jon and Becky explore the mathematics behind space travel, inspired by the recent Artemis mission and the return of astronauts from their journey around the Moon. Starting with the sheer scale of the challenge, they unpack the numbers, distances, and precision required to send humans into space and bring them safely home again. The conversation compares the Apollo missions of the 1960s with today’s Artemis programme, highlighting how technology has advanced dramatically while the underlying mathematics has remained the same. From trajectory calculations and launch angles to predicting where the Moon will be, this episode brings big mathematical ideas into a form that teachers can share with their pupils. The episode then focuses on the remarkable story of Katherine Johnson, whose calculations were critical to the success of early space missions, including Apollo 11. Her work reminds us that mathematics is far more than arithmetic. It is about reasoning, modelling, and solving real problems that matter. Along the way, Jon and Becky reflect on what this means for the classroom, why the maths we teach in primary school matters more than we might think, and how stories like this can inspire children to see themselves as mathematicians.

Financial Literacy, Inequality and the Role of Parents - With Dr Paula Fieldhouse

Hello and welcome to this interview episode of The Primary Maths Podcast, the show where we talk all things primary maths. I’m Jon Cripwell. In this episode, I’m joined by Paula Fieldhouse for a wide-ranging conversation about financial literacy, parental engagement, and what it really means to prepare children for the financial decisions they will face later in life. We explore what financial literacy actually is, beyond budgeting worksheets and coin recognition, and why children’s early experiences of money at home play such a powerful role in shaping their attitudes, confidence and behaviours. Paula shares insights from her research into how families talk about money, how inequality shows up long before formal financial education begins, and why schools on their own cannot solve this issue. We also discuss common misconceptions, including the idea that financial education is something that can be bolted on later, or that it sits outside the maths curriculum. Paula explains why parental engagement matters so much, what meaningful support for families can look like, and how initiatives like Learning with Parents are helping to bridge the gap between home and school in a practical, respectful way. This episode will be particularly relevant for teachers, maths leads and school leaders thinking about inclusion, equity and real-world application in mathematics, as well as anyone interested in how education systems can support families rather than work around them.

AfterMaths: Kaprekar’s Constant, Odd Numbers and Everyday Problem Solving

In this Aftermaths episode of The Primary Maths Podcast, Jon and Becky return after the Easter break with a lighter, curiosity-driven conversation that blends real mathematics with everyday life. Jon introduces a fascinating mathematical quirk known as Kaprekar’s constant. Starting with almost any four-digit number and following a simple process of rearranging and subtracting digits, you will always arrive at 6174. It is a brilliant example of how pattern, structure and curiosity can bring maths to life, and offers a simple but engaging classroom investigation. The conversation then shifts into “Maths of Life”, as Becky shares a very relatable problem: calculating the area of an awkwardly shaped driveway. What follows is a great discussion about different ways to break down complex shapes, and how mathematical thinking allows us to approach the same problem in multiple valid ways. Finally, Becky brings back “Etymathsology”, exploring the origins of mathematical language. This week includes the surprising Norse roots of the word “odd”, the evolution of “even”, and the historical meaning of “score” as a way of counting in twenties. As ever, the episode is a reminder that maths is everywhere, from number curiosities to home improvements to the words we use every day.

AfterMaths - The Easter Special: Eggs, Estimates and Everyday Maths

In this Easter special of The Primary Maths Podcast, Jon and Becky take a slightly lighter turn while still keeping one foot firmly in the world of maths. Recorded on Good Friday, the episode reflects on the welcome arrival of the Easter break and the importance of slowing down after a busy term. The conversation explores a familiar classroom question: what do we do with seasonal contexts like Easter? Jon and Becky discuss the difference between simply dressing up maths with a theme and genuinely finding the mathematics within real-life situations. From hot cross buns to chocolate eggs, they consider how context can support engagement, while also reflecting on the challenge of finding time to explore it properly. There is, of course, an Easter quiz. Jon puts Becky on the spot with a series of statistics, including how many Easter eggs are eaten in the UK each year, the scale of chocolate production and the surprisingly specific history of the first chocolate eggs in Britain. Expect a mix of sensible estimates, near misses and the occasional wildly inaccurate guess. Along the way, the episode returns to a key idea that runs through the podcast: maths is everywhere. Even if there is not always time to build a full lesson around it, simply noticing and talking about the maths in everyday life can make a real difference. To finish, Jon and Becky share their Easter preferences, reflect on how traditions have changed, and make a strong case for bringing back Easter eggs that come with a mug.

AfterMaths: From Capybara Escapes to The MTC: Real World Maths

In this Aftermaths episode of The Primary Maths Podcast, Jon and Becky catch up after a short break and reflect on this week’s interview with Professor Lucy Cragg on multiplication and how children learn times tables. The conversation turns to the Multiplication Tables Check (MTC), exploring its origins, purpose and impact since its introduction. Jon shares a short history of the check, from its announcement in 2017 through to its first full national rollout in 2022, and discusses what the latest data and Teacher Tapp findings suggest about its influence on teaching and learning. They consider the benefits of increased focus on multiplication fluency, alongside some of the tensions around assessment, accountability and the risk of prioritising speed over understanding. The discussion raises an important question: does rapid recall alone support deeper mathematical thinking, or are we missing something? Becky then brings this week’s Maths of Life, inspired by a real-life capybara escape near her home. Using the scenario, she explores how maths can be used to model search areas, introducing ideas around radius, area and real-world problem solving. It’s a reminder of how powerful local and engaging contexts can be in the classroom. The episode finishes with Research in 60 Seconds, focusing on Mary Budd Rowe’s work on wait time. Increasing thinking time from one second to three seconds can significantly improve the quality of pupil responses, increase participation and deepen reasoning. Jon and Becky reflect on how this simple shift can have a meaningful impact in everyday classroom practice. As always, the episode blends practical insight, research and a few lighter moments along the way.

What Cognitive Science Tells Us About Learning Times Tables - with Professor Lucy Cragg

In this episode of The Primary Maths Podcast, Jon speaks with Lucy Cragg, Professor of Developmental Psychology at the University of Nottingham, about what cognitive science reveals about how children learn multiplication facts. Lucy’s research explores executive function skills such as working memory, inhibitory control and cognitive flexibility, and how these shape children’s mathematical learning. The conversation dives into how multiplication facts are stored and retrieved, why certain errors (like 6 × 7 = 42) are so common, and what this tells us about the structure of memory. Together, Jon and Lucy explore the distinction between fluency and understanding. While more pupils are improving their scores on England’s Multiplication Tables Check, Lucy explains why improved recall does not automatically translate into stronger applied mathematical reasoning. Drawing on findings from the ESRC-funded SUM Project, she discusses how children can improve fact recall without a corresponding gain in multiplicative understanding. The episode also tackles maths anxiety, the impact of timed practice, and why speed may matter for testing but not necessarily for learning. Lucy shares practical insights for teachers, including the benefits of varied practice, careful use of multiple-choice formats, and ensuring that multiplication facts are connected to meaningful mathematical structures rather than learned in isolation. This is a thoughtful and research-informed conversation for teachers and leaders who want to understand not just how to help children remember their times tables, but how to help them truly understand multiplication.

Helping Every Child Feel Like a Mathematician - with Tom Oakley

In this episode of The Primary Maths Podcast, Jon Cripwell speaks with Tom Oakley about one of the most important — and often overlooked — aspects of mathematics education: belonging. Why do some pupils decide that maths “isn’t for them”? Why do confident learners sometimes disengage from mathematics? And what can teachers do to help every child feel like they belong in the maths classroom? Tom draws on research around motivation, self-perception and classroom culture to explore how children develop their identity as mathematicians. The conversation looks at how pupils’ beliefs about themselves are shaped over time through small classroom experiences — and how teachers can design lessons that help pupils feel successful, valued and able to contribute. The discussion also explores the difference between behavioural engagement and cognitive engagement, why success and motivation reinforce each other, and how carefully designed routines and questioning can help pupils build confidence in mathematics. Along the way, Tom shares practical strategies teachers can use straight away, including partner discussion routines, improving the use of mini whiteboards, and structuring lessons so that pupils experience meaningful success before encountering challenge. If you want to create maths lessons where every child feels like they matter — and where thinking is valued as much as answers — this episode is packed with ideas you can take straight back to the classroom. About Tom OakleyTom Oakley is a Deputy Headteacher at a primary school in Suffolk, England. Previously, Tom worked as a lead teacher for mathematics in south-west London and later as a Local Authority Maths Adviser in Cambridge for six years.
