Maths for Kids / Maths is Not Boring: The Kids Maths Podcast
Maths for Kids / Maths is Not Boring is a podcast for curious children aged 4 to 12. Each episode explores one big mathematical idea, from infinity and prime numbers to chance, shapes and patterns. It is hosted by fictional AI characters Mira, a nine-year-old, and her seven-year-old brother Finn. The show avoids arithmetic drills and instead uses stories to show how maths explains the world. It aims to make mathematical ideas feel simple, beautiful and relevant to kids.

What is the Collatz conjecture?
Have you ever heard of a math puzzle that acts like a wild weather storm? In 1937, a mathematician named Lothar Collatz invented a simple number machine with just two rules: if a number is even, cut it in half. If it is odd, multiply it by three and add one! Sounds easy, right? But what happens next is pure magic! Instead of acting normally, the numbers bounce wildly up and down like hailstones ca

What was the first times table?
Have you ever wondered who invented times tables? Or why three times four is exactly the same as four times three? It's time to discover the quiet magic of multiplication! Imagine lining up your favorite wrapped sweets on a table in three rows of four. Now, walk around to the side of the table. Suddenly, it looks like four rows of three, but you haven't moved a single sweet! Mathematicia
