Dedicated Year 4 resources for recognising apostrophes in both contraction (omission) and possession contexts, a core KS2 Grammar, Punctuation and Spelling (GPS) objective. Activities build conceptual understanding of the dual function of the apostrophe, promoting reasoning in sentence analysis and editing. This essential small step supports national curriculum expectations for punctuation accuracy and develops writing mastery. The CS Grammar, Punctuation and Spelling Scheme provides structured identification practice.
