    Can Maths Help You Win at Games?

    Can maths help you win at games? In this AfterMaths Summer Special, Jon and Becky explore the line between luck and strategy — and whether understanding the maths behind a game can actually give you an advantage. They take in Rock Paper Scissors, Noughts & Crosses, chess, a deceptively simple counting game, the chessboard-and-rice problem, expected value, roulette and the mathematics hiding inside Monopoly. Along the way: why some apparently random games aren’t quite random, why exponential growth gets ridiculous remarkably quickly, why the house tends to win at casinos, and how a little probability might improve your chances during family game night. Maths can’t guarantee that you’ll win every game. But it might make people considerably less keen to play Monopoly with you.

    Can Maths Predict the Future?

    Can maths really predict the future? We can predict the return of a comet decades in advance, but tomorrow's weather can still catch us completely by surprise. In this AfterMaths Summer Special, Jon and Becky explore why some futures are easier to calculate than others. From probability, forecasts and projections to Halley’s Comet, the phantom planet Vulcan and Edward Lorenz's discovery of chaos theory, they ask how much mathematics can genuinely tell us about what happens next. There's also the butterfly effect, an unexpectedly important rounding error, the difference between chaos and randomness — and the small problem that human beings refuse to behave like nice, predictable mathematical models. Especially children. So, can maths predict the future? Sort of. Which is perhaps the most mathematically appropriate answer possible.

    The Maths of Getting Away: Routes, Queues & Google Maps

    Podcast Show Notes What makes a route the best route? The shortest distance? The quickest journey? The cheapest option? Or simply whichever one Google tells you to take? In this AfterMaths Summer Special, Jon and Becky explore the maths of getting away — from Google Maps and traffic predictions to queues, theme parks and an 18th-century puzzle that helped create an entirely new area of mathematics. Along the way, they discuss the Seven Bridges of Königsberg, Euler's ingenious solution and what it can teach us about problem solving: representing problems, working systematically, spotting patterns, simplifying and knowing when there might not actually be a solution at all. Plus: why the other supermarket queue is always faster, whether you should ever switch queues, 99 smartphones causing a fake traffic jam in Berlin, and the deeply troubling emergence of people forming orderly queues at pub bars. It's maths. It's holidays. It's considerably more Euler than your average trip to Orlando.

    Who Decided How Long a Metre Is? AfterMaths Summer Special 3

    Who decided how long a metre should be? Why is a mile 1,760 yards? And what connects the French Revolution, an expedition from Dunkirk to Barcelona and the speed of light? In this AfterMaths Summer Special, Jon and Becky explore the messy, surprising and occasionally bewildering history of measurement. They begin in a world before standard units, when lengths were measured using hands, feet, cubits, spans and paces. These methods were convenient and widely understood, but rather less useful when accuracy mattered and everybody’s body produced a different answer. From there, they investigate the historical accumulation that gave us imperial units, including the supposed connections between inches and barleycorns, feet and actual human feet, and miles and Roman paces. The story then moves to revolutionary France, where mathematicians and astronomers attempted to create a universal decimal system based on the dimensions of the Earth. Their effort to establish the metre involved years of surveying, triangulation, political upheaval, arrests and the inconvenient discovery that neither the Earth nor their measurements were quite as perfect as hoped. The metre was later represented by a platinum-iridium bar, then by a wavelength of light and, finally, by the distance light travels through a vacuum in a precisely defined fraction of a second. It is a journey from body parts to universal constants, with plenty of mathematical history, questionable conversions and the inevitable disagreement about whether a pace and a “dolly step” are the same thing.

    The Probability Problems That Make Your Brain Hurt - AfterMaths Summer Special 2 2026

    Probability often feels as though it should be intuitive, right up until the mathematics tells us that our instincts are completely wrong. In this AfterMaths Summer Special, Jon and Becky explore the strange mathematics of chance. From rainy-day board games and rolling two dice to coin-toss streaks, lottery numbers and casino myths, they investigate why humans are so determined to find patterns in genuinely random events. Why is seven the most likely total when rolling two dice? How can just 23 people produce a better-than-even chance of two sharing a birthday? Are 1, 2, 3, 4, 5 and 6 genuinely bad lottery numbers? And after choosing between three mysterious doors, why should you abandon your original choice? The episode concludes with the famously counterintuitive Monty Hall problem: three doors, two goats, one car and a very good mathematical reason to switch. Expect hidden maths, questionable gambling strategies and several probability problems capable of making your brain hurt.

    Why Do Summer Holidays Feel Shorter As We Get Older? Summer Special 1 2026

    Why did the six-week summer holiday feel endless when we were children, yet now seems to disappear almost as soon as it begins? In the first of the 2026 Aftermaths Summer Specials, Jon and Becky explore the strange relationship between time, age and memory. They consider the popular proportional theory of time, the role of novelty in creating richer memories and the “return-trip effect”, which can make the journey home feel shorter even when the distance is the same. The conversation also takes in unusually long post-GCSE summers, children’s television, World Cup statistics and the role of the railways in creating standardised time across Britain. Before that, Jon and Becky discuss Andy Burnham’s arrival in Downing Street and Lucy Powell’s appointment as education secretary. What might the change mean for schools—and can the sector retain some much-needed continuity around SEND, curriculum reform, funding, recruitment and retention?

    KS2 SATs Results, AI and Outsourcing Mathematical Thinking

    What do this year’s KS2 SATs results really tell us about primary maths—and what might they be hiding? Jon and Becky examine the newly released national data, including the rise in maths attainment, the return of greater-depth results to pre-pandemic levels and the growing number of pupils working below the level of the tests. They discuss why a single score can never tell the whole story, why missing the expected standard does not mean a child “can’t do maths”, and whether the improving headline figures may be masking a widening gap between different groups of pupils. They also explore new research into pupils’ use of AI for mathematical word problems. Homework accuracy increased and answers were completed in seconds—but performance fell when pupils had to work independently under supervision. Are pupils using AI as a helpful learning tool, or simply outsourcing the thinking that helps learning happen?

    Teaching in a Heatwave and is there a Place for Maths Hacks?

    In this episode of the Primary Maths Podcast, Jon and Becky ask whether we need to change the way we teach maths during a heatwave. With classrooms getting hotter and the end of term in sight, they explore what heat can do to attention, working memory, processing speed and classroom engagement. Is it just children being tired and sticky, or is there a genuine cognitive load issue at play? They also tackle one of the classic primary maths debates: when multiplying by 10, is it ever OK to say you “put a zero on the end”? Jon and Becky discuss place value, mathematical shortcuts, misconceptions, decimals, fluency, relational understanding and why seeing the structure matters more than simply getting the answer quickly. Plus, there’s ice cream ratios, hydration breaks, the Fosbury Flop, Richard Skemp, Jerome Bruner and a reminder that the brand-new PlanIt Maths Place Value resources are now available.
