“Explain the concept of HCF to a Class 5 student.”
- Did you actually pitch it at a ten-year-old, or recite the definition?
- Did you use a concrete example before any formula?
- Did you check the child had understood, or just keep talking?
Candidates start with prime factorisation. A Class 5 child has no use for it. The panel is testing whether you can meet a child where they are — not whether you know what HCF is.
