Using Izak9 to Explore Prime Numbers and their Multiples

9th Oct 2025
Our Primary Seven girls demonstrated great expertise in number this morning. With the use of our Izak9 equipment, the girls explored prime numbers and calculated the multiples of given primes. For example, ‘calculate the first five multiples of the prime number that comes immediately after 23.’ Well done, girls!
