S03E12 - Daniel Ansari on Number Sense, Fluency and Understanding Math Difficulties
Knowledge for Teachers
Exploring the Connection Between Dyslexia and Dyscalculia
This chapter explores the significant overlap between dyslexia and dyscalculia, revealing that many students face challenges in both reading and math. It emphasizes the need for tailored interventions and a more integrated understanding of these learning disorders.
What do young children really need to understand about numbers? And why do some students struggle so much with maths—even from the very beginning?
In this insightful episode, I’m joined by Professor Daniel Ansari, a leading cognitive neuroscientist whose work has shaped how we understand early mathematical development. We explore what number sense actually is, why symbolic understanding is so important and how to build arithmetic fluency without creating anxiety.
Daniel also unpacks key ideas around subitising, dyscalculia and the role of spatial reasoning in maths success. If you teach in the early years or support students who find maths difficult, this episode is packed with practical insights you can take straight into your classroom.
Tune in for an evidence-based conversation that will empower you to better support every child's mathematical journey, fostering confidence, fluency and a genuine love for maths!
