Spot the Difference: Possessive vs Plural Nouns for Grade 3

With engaging activities such as MCQs, true/false checks, punctuation correction, sentence rewriting, and paragraph editing, this worksheet builds strong grammar foundations. The tasks are age-appropriate and practical, helping children apply grammar rules correctly in everyday reading and writing.
