Learning journey

Your child is mastering more complex multiplication and division — working with larger numbers, understanding factors and multiples, solving multi-step problems, and beginning to use formal written methods.

Evidence of understanding

  • List all factor pairs of 36: (1,36), (2,18), (3,12), (4,9), (6,6)
  • State the first five multiples of 7
  • Find the common factors of 24 and 36
  • Find all common factors of 36 and 48
  • Identify the first three common multiples of 6 and 8
  • Determine whether a given number (e.g. 97) is prime and justify the reasoning

Assessment prompt

Can Factors, multiples, and primes list all the factor pairs for a number like 36 — (1, 36), (2, 18), (3, 12), (4, 9), (6, 6) — and find factors that two numbers share?
