What's taught in South African schools is at odds with the skills pupils need for the post-school world.
School boards across the country are using different measures to stop the spread of COVID-19. A new study suggests rotating students during different times at school could be most effective.
What did Pythagoras do with all those triangles, anyway?
Nobody expected that allowing more communication would make computational problems more reliable.
Long breaks from school lead to learning loss, with maths scores being particularly badly affected - but a return to core concepts could be the answer to a pre-pandemic problem.
Mathematically speaking, the Electoral College is built to virtually ensure narrow victories, making it very susceptible to manipulation and disinformation.
Without a vaccine, the cost of reaching herd immunity during a pandemic is counted in lives lost, and it won't quickly stop the virus's spread.
Some animals demonstrate an ability for mathematics that reflects a more sophisticated understanding of language.
The equation 'COVID alert level = R (rate of infection) + number of infections' simply does not add up to a number between one and five.
Christopher Havens came upon his love of math while in solitary confinement. A decade later, he published a paper on number theory in a top mathematics journal.
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.
Testing everyone for COVID-19 isn't realistic in a country the size of the US, but there are ways to design testing systems that can catch most of the cases.
Here's one way to test more people for coronavirus with fewer resources.
The awesome power of exponential growth explained.
Exponential growth, such as in a viral epidemic, starts deceptively slowly, then quickly balloons. A mathematician explains the importance of early action and the costs of delay.
Can statistics work out who will win the various tournaments?
A major reason for poor performance in mathematics in Nigeria is that lessons in primary schools are not centred on pupils and activities.
You don't have to believe the official figures to realise that the rate of spread of the virus in Japan has been slower than in other countries.
Currently, the number of confirmed global COVID-19 cases is doubling about every six days. At this rate, Australia's health sector will be unable to cope.
Math is not primarily about numbers, but about thinking. It all begins with parent-child conversations about mathematical ideas.
