Division as Unknown Factor
Understand division as an unknown-factor problem (e.g. find 32 ÷ 8 by finding the number that makes 32 when multiplied by 8)
Suggested ages 8–9
Learning journey
Your child is building fluency with multiplication and division — memorizing times tables up to 12×12, understanding the relationship between multiplication and division, and solving word problems involving equal groups and arrays.
Evidence of understanding
- Explain that 32 ÷ 8 = ? is the same as 8 × ? = 32
- Use a known multiplication fact to find a division answer
- Describe the relationship between multiplication and division as inverse operations
Assessment prompt
Can Division as Unknown Factor work out '32 ÷ 8' by asking 'what do I multiply 8 by to get 32?' — using times table knowledge rather than a separate division method?
