4th Grade Sentences Worksheets

Fourth graders should write complete sentences and fix the two errors that break them: fragments and run-ons (CCSS L.4.1f). By the end of the year, your fourth grader can find the complete subject and complete predicate, tell the difference between a fragment, a run-on, and a full sentence, and repair each one. They learn to join short, choppy sentences into one clear sentence using a comma and a coordinating conjunction (L.4.2c), and to build compound subjects and predicates so their writing flows. Fourth grade also adds sentence variety: classifying the four sentence types (declarative, interrogative, imperative, exclamatory), starting sentences different ways, adding an introductory clause with a comma, and choosing precise words for effect (L.4.3a). They practice subject-verb agreement, including the tricky cases where a phrase sits between the subject and the verb, and they clean up double negatives. The goal is not just correct sentences but varied, purposeful ones. Worksheets that move from spotting fragments and run-ons to combining, expanding, and classifying sentences give students the repeated, targeted practice these standards expect.
