identify and describe the properties of prime, composite, square and triangular numbers and use these properties to solve problems and simplify calculations
Elaborations
using the definition of a prime number to explain why one is not a prime number
testing numbers by using division to distinguish between prime and composite numbers, recording the results on a number chart to identify any patterns
representing composite numbers as a product of their factors, including prime factors when necessary and using this form to simplify calculations involving multiplication, such as 15 × 16 as 5 × 3 × 4 × 4, which can be rearranged to simplify calculation to 5 × 4 × 3 × 4 = 20 × 12
identifying and describing the product of a number with itself as square; for example, 3 × 3 is the same as 32
using spreadsheets to list all the numbers that have up to 3 factors, using combinations of only the first 3 prime numbers, recognising any emerging patterns, making conjectures and experimenting with other combinations
