This activity is part of the module "Code by Numbers" which can be downloaded as complete booklet from the STEM section of the website. In this activity students explore the prime factorisation of a number and the total factor count with a view to establishing a rule to determine the quantity of factors for any number, based on the prime factorisation. Students write a program to determine the quantity of factors.
This activity covers multiple objectives including improved number sense, review of prime factorisation, pseudo-coding, coding, algorithmic thinking, problem solving and investigations.

About the Lesson
This activity is Part 1 of the series Code by Numbers. This activity requires students to establish a relationship between the prime factorisation of a number and the quantity of factors for the number. The result will be very useful in subsequent activities!
