This short article gives an outline of the origins of Morse code and its inventor and how the frequency of letters is reflected in the code they were given.
Who's the Best?
Age 11 to 14 Challenge Level:
In this problem, we needed to find a way to use the Olympic medal tally in order to work out which country is the most athletic.
Gianluca from Salesian School in Chertsey sent us his excellent analysis of the Olympic tally. He made use of a scoring system for each type of medal and also took into account the population of each country. You can find his analysis here, thank you Gianluca!
Can you find a mathematical method to find the most athletic nation using information about the number of medals, population size and country wealth? Or perhaps you could consider other data, such as sporting event results, population age, prevalence of obesity, and investment in Olympic althetes to determine which country is the most athletic.
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice.
