Sentence Surgery

This grammar editing worksheet gives students the opportunity to act like sentence doctors by diagnosing and repairing mistakes involving do, does, and did. Learners read each sentence carefully, determine whether the helping verb matches the subject and tense, and rewrite incorrect sentences correctly. The activity focuses on common grammar errors that frequently appear in student writing and speech, helping children develop stronger editing habits. Best suited for grades 2-4, this worksheet builds confidence with verb agreement, question formation, sentence structure, grammar conventions, and proofreading skills.

Students often know grammar rules in isolation but struggle to apply them consistently in writing. This worksheet strengthens grammar awareness, sentence fluency, verb usage, editing strategies, language conventions, and writing accuracy through meaningful correction practice. By identifying mistakes and rewriting sentences, learners become more attentive to how helping verbs function within different contexts. The process encourages careful reading and thoughtful revision habits that transfer to broader writing tasks. Over time, students gain greater confidence using do, does, and did correctly in both written and spoken language.
