Original Prompt

Create a Grade 5 worksheet on Prime Factorisation Using Factor Trees. The worksheet must include: A simple explanation of what prime numbers are and what prime factorisation means (kid-friendly, Grade 5 level). Two worked examples, showing step-by-step how to complete factor trees (e.g., 54 and 36). Guided practice section where the child completes factor trees with partial steps already provided. Independent practice section with 6–8 factor tree questions for the student to solve on their o...

This resource focuses on the concept of prime factorization, teaching students how to decompose composite numbers into their prime factors using factor trees. It begins by explaining what prime numbers are, defining them as numbers greater than 1 that have only two factors: 1 and themselves, with examples provided for clarity. The document includes a thorough explanation of prime factorization, describing it as the process of breaking down a number into its prime building blocks. Students will learn how to construct and use factor trees, starting with a composite number and branching into its factors until all resulting numbers are prime. The guide includes worked examples, exercises for guided and independent practice, and an answer key for self-assessment. It also touches upon the relevance of prime numbers in real-world applications such as cryptography.
