What did Pythagoras do with all those triangles, anyway?
If you discuss ideal parts of cocoa to sugar, you’ve just discussed ratios.
Improving a child's sense of numbers, and their understanding of probability, fractions, ratios, shapes and patterns, can all be incorporated into daily life or with simple games.
What does it mean for students if they are learning that technology can answer every challenge?
Technology in the math classroom should enhance and extend, rather than replace, how to think mathematically.

Supreme Court justices have previously called statistical methods of measuring partisan gerrymandering 'sociological gobbledygook' and 'a bunch of baloney.'
A Mobius strip.
The inventor of the brain-teasing Möbius strip died 150 years ago, but his creation continues to spawn new ideas in mathematics.
Getting ready for school.
Through games and household tasks, parents can help their children learn basic math skills like counting, geometry and algebraic thinking.
DNA knot as seen under the electron microscope.
Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.
Math in yarn.
In this professor's class, there are no calculators. Instead, students learn advanced math by talking, drawing pictures, playing with beach balls – and knitting.
Illinois’s Fourth Congressional District is often called out for its ‘earmuff’ shape, but there’s an ideal behind its strange appearance.
Gerrymandered districts are under fire across the US. But a weird district shape isn't necessarily a bad one.
How can geometry track with our political values?
Gerrymandering is being hotly debated around the US. Can math help us figure out how to divide the country up fairly?

Mirzakhani blazed to the top of her field due to her talent. But who she was and where she came from also make her a role model for those from underrepresented demographics in the world of math.
Is there a geometry lesson hidden in ‘The Last Supper’?
Mathematics and art are generally viewed as very different. But a trip through history – from an Islamic palace to Pollock's paintings – proves the parallels between the two can be uncanny.
The frilly forms of corals and sponges are biological variations of hyperbolic geometry, as seen here on the Great Barrier Reef, near Cairns, Queensland, Australia.
The magic and wonder of the mathematics of straight lines in curved spaces is best explained when you look to nature for examples.
General relativity didn’t happen overnight, but took several steps to come to fruition.
This month is the centenary of the general theory of relativity. But how did we get from the absolutism of Newton to the relativity of Einstein?
Surfaces like this are able to be described thanks to the work of Nash.
John Nash is best known for his contributions to game theory, but he will also be remembered for his pioneering work in geometry.

Kazimir Malevich unveiled his now iconic pared down painting of a black square on a white background in 1915. This was a moment that not only represented a turning point in art, but in politics too. This…
The Sydney Opera House, an icon of Australia’s creative and technical achievement. It has won worldwide acclaim for its design and construction.
What do the façades of the National Gallery in London’s Trafalgar Square and the Sydney Opera House in Australia have in common? Most people would suggest the two buildings have few similarities – the…
