Free 4th Grade Grammar Worksheets & Practice
4th grade grammar practice shifts toward sentence-level editing — fixing sentence fragments and run-ons, and combining ideas into compound and complex sentences — plus subject-verb agreement and continued parts-of-speech and verb-tense practice from 3rd grade. Capitalization, contractions, and plural nouns are treated as already-mastered here, so this page focuses on what's genuinely new. Every worksheet is free, prints instantly, and comes with an answer key.
