Maths and Stats by Email | Prime numbers, Advent puzzle: "Article: Why do mathematicians care about prime numbers?  
   

Once again, the maths world is celebrating a triumph regarding prime numbers. Earlier this year we reported on a new result by mathematician Yitang Zhang. His proof showed that there were infinitely many pairs of primes within 70 million of each other. Several mathematicians took Yitang’s work and refined the range from 70 million down to 4680. Now James Maynard has written a proof bringing the range down to 600, and has also investigated triplets and larger collections of primes. But why are mathematicians so interested in prime numbers?

Maths and Stats by Email | Money: "Article The value of money  
   

It’s clear that a one dollar coin is worth two 50 cent coins. Yet here in Australia, 50 cent coins are bigger, heavier, and made of similar metals. So why is the dollar coin worth more?

The short answer is that government tells us. In Australia, there are many laws about our money. One important law in this country states that Australian money must be accepted as a method of payment. These laws make sure that a one dollar coin is worth one dollar. But this isn’t the only way that money can be valued."

Teaching Ratio and Proportion in the Middle Grades

Teaching Ratio and Proportion in the Middle Grades: "Proportional reasoning is one of the most fundamental topics in middle grades mathematics. Students’ ability to reason proportionally affects their understanding of fractions and measurement in elementary school, and it supports their understanding of functions and algebra in middle school and beyond. Given the importance of ratio and proportion, it is typical to see extensive class time devoted to the topic in upper elementary and middle school grades. This research brief addresses the research on what it means to understand ratio and proportion and how teachers can best support that understanding."
