Co-primes
In this Nuffield investigation these resources from AMP, co-funded by the Clothworkers and Nuffield Foundation, students investigate how many positive integers are less than and co-prime to any given positive integer. This activity requires some confidence with the co-prime property, division and divisibility tests. It would also be useful for students to be aware of prime factorisation.
The key processes developed by this investigation are:
*Representing - choosing to move the situation from numerical examples to more abstract symbolism.
*Analysing - working with a logical approach and generating accurate results.
*Interpreting and evaluating -identifying patterns and developing generalisations, considering the findings and relating answers to the original task.
*Communicating and reflecting - providing evidence of the methods used, presenting the results obtained and the conclusions drawn from them.
