Proving That an Answer Must Be True (Teach This Topic)

This guide supports a home-educating parent in teaching the difference between an answer that seems correct and a conclusion that must be true. It provides a clear sequence, self-contained written tasks and answers using parity, divisibility, bounds, geometry and logical coverage. Adapt the pace to the learner while keeping the central question in view: why must the conclusion follow from the stated conditions?
