Factors, multiples, and primes (age 9+)
Solve problems involving multiplication and division using knowledge of factors, multiples, squares, and cubes
Lesson
Set out your lesson
“Factors, multiples, and primes (age 9+) means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Small counters or grid paper
- Paper and pencil
Extra for the adult
Worked example. Three rows of four counters make 12. Write 3 × 4 = 12.
Optional challenge. For Factors, multiples, and primes (age 9+), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Factors, multiples, and primes (age 9+), not mastery.

Check understanding
- 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
“If your child 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?”
