Run-On Repair

Run-On Repair helps students correct sentences in which two complete thoughts have been pushed together without proper punctuation or a connecting word. Students read each run-on sentence, identify the two independent clauses, and rewrite the sentence using a comma and an appropriate coordinating conjunction. The worksheet strengthens run-on correction, independent clauses, compound sentences, comma placement, FANBOYS conjunctions, sentence boundaries, and editing skills. It is especially useful for students in grades 4-6 who can express several ideas but need help separating and joining those ideas correctly.

Instructional Objectives

• Find two complete thoughts: Students identify the independent clauses hidden inside each run-on sentence.
• Choose a logical conjunction: Learners select for, and, nor, but, or, yet, or so to show the correct relationship.
• Add proper punctuation: Students place a comma before the coordinating conjunction.
• Rewrite for clarity: Children turn each confusing run-on into a smooth and correctly formed compound sentence.

Learning Benefits

• Targets a common writing problem: Students practice repairing the kind of run-on sentences that often appear in first drafts.
• Makes clause boundaries visible: Learners begin noticing where one complete thought ends and another begins.
• Supports parent guidance: Adults can ask, “Can you find the two parts that could each be a sentence by themselves?”
• Works across settings: The page fits grammar lessons, writing intervention, homework, tutoring, or homeschool practice.
• No-prep format: Teachers and parents can print the worksheet and begin immediately.

Run-on sentences happen when a writer has two good ideas but does not show the reader where one thought ends and the next begins. A simple repair is to place a comma after the first independent clause and add a conjunction that explains how the ideas relate. For example, but can show contrast, so can show a result, and and can add closely related information. As students revise the sentences, they strengthen clause recognition, conjunction choice, comma accuracy, editing awareness, sentence fluency, and confidence. In classroom and homeschool settings, this worksheet reinforces clearer communication and gives children a practical strategy they can use when revising their own paragraphs.
