Common mistakes
What learners typically get wrong, and how to fix it.
Confident students rush runtime errors and skip the checking step.
Correction: Build in an estimate-before-solve routine so an unreasonable answer stands out.
Learners over-generalise a special case of runtime errors to every situation.
Correction: Present a deliberate non-example and ask why the rule fails.
