What mastery looks like

  • Is 156 a multiple of 6? Explain how you know
  • Find two square numbers that add to make 100
  • Use factor pairs to simplify 24 × 25 as 6 × (4 × 25) = 6 × 100 = 600

Check your understanding

If Factors, multiples, and primes (age 9+) is asked to find all the square numbers less than 100, can they work through it systematically and give you the correct list: 1, 4, 9, 16, 25, 36, 49, 64, 81?
