3rd Grade Grammar Curriculum Overview
Third-grade grammar instruction covers more nuanced language structures that directly support the increased writing demands. Under Common Core L.3.1, students learn to explain the function of nouns, pronouns, verbs, adjectives, and adverbs in sentences. They form and use regular and irregular plural nouns, use abstract nouns ("courage," "freedom"), form and use regular and irregular verbs in all tenses, and ensure subject-verb and pronoun-antecedent agreement. Sentence work includes producing simple, compound, and complex sentences. Punctuation skills expand to include commas in addresses, commas and quotation marks in dialogue, and forming and using possessives. Students learn to use conventional spelling for high-frequency and studied words, consult reference materials to check spelling, and choose words for effect. Third grade is when grammar instruction becomes visibly connected to writing quality — students who master these conventions produce noticeably clearer, more polished compositions.
