What kinds of shapes pack a flat surface with no gaps? Squares are great for floor tiles, and bees stick hexagons together. With a bit of work, you can get any triangle, no matter how stretched, to fit together without gaps. But what about pentagons? These five-sided shapes are awkward, but some types fit together.

Have you ever made a paper snowflake? Here’s a different twist on a classic craft activity.

Time to create a map! Making a map of the entire Earth is tricky, because paper is flat, and planets are curved. There are lots of different ways to ‘flatten’ Earth, and each way produces a different shaped map. This method is super spiky as it involves triangles.

Maths is everywhere! But it can be hard to find if you don’t know what to look for. Try this mathematical treasure hunt and you’ll soon discover some amazing mathematical secrets!

Here’s a quick puzzle for you – this square is too wide for its envelope. Can you find a way to make it fit?

Written by Rachael Vorwerk Inside a small sample of powder, there hides a gigantic secret. In just a teaspoon of the stuff you’ll find the entire surface area of a football field. It sounds like something from Back to the Future, but for CSIRO scientists it’s the norm.

Feeling festive? This cool mathematical bauble is fun to make, and looks great too!

Picture this: you’ve just bought a nice little cake, just for you. Then your friends show up, wanting a piece. Lucky for you, mathematicians have developed some pretty cool ways of sharing.

There are plenty of patterns inside a flower. Let’s follow one and see what drawing we get!
