This resource focuses on determining whether a number is prime or composite by analyzing its factors. It includes a worked example with the number 8, demonstrating that it has more than two factors (1, 2, 4, 8), thus classifying it as a composite number. The document features two tasks where learners investigate the factors of the numbers 13 and 15, asking them to list each number's factors and complete classification sentences. This activity aims to reinforce the understanding of prime and composite numbers through hands-on exploration.
