Off-the-shelf Primary Mathematics Masterclass about prime numbers and the patterns they hold.
Investigate the random nature of primes and the unusual patterns that emerge as you delve into them. Use a special number sieving technique to identify primes in large number grids.
Prime numbers, and their random nature, are fascinating to lots of people from school children to experts. In fact, research into this field by mathematicians is still very active. This Masterclass was inspired by mathematician Dr Vicky Neale, and her book 'Closing the Gap' charting the on-going quest of researchers to better understand prime numbers.
Through the activities in this session and watching a clip from Vicky Neale's 'Closing the Gap' video, students are able to delve more deeply into primes. Their exploration involves simple activities with factor numbers and more complex challenges to generalise properties of prime numbers (and maybe even an attempt to predict primes!). Using the Sieve of Eratosthenes, they identify primes in large number grids and are finally shown the applications for prime number research in the field of cryptography.
With questions presented in this workshop verging on the philosophical at times, presenters navigate these with ease using the solution sheets for each worksheet and the handy speaker notes.
Length: 2 hours (see the session leader notes for ideas on how to shorten the Masterclass).
All supporting notes, worksheets and solutions can be downloaded from this page along with the Powerpoint presentation.
The Session Leader Notes offer full notes on the activities and a detailed list of resources, including quantities needed.
The Session Helper Notes can be distributed amongst helpers giving them an overview of the subject and activities planned.
