Every complete sentence needs a subject and a verb to express a whole thought. A fragment is missing one of these parts, like writing "Running down the street." A run-on happens when two complete thoughts are smashed together without the right punctuation, like "I love reading books they are fun." To fix a run-on, add a comma and a conjunction, or split it into two sentences.

Why Mastering Sentence Structure Matters in Seventh Grade
By seventh grade, students are expected to write complex essays and analytical paragraphs. When fragments and run-on sentences slip into their writing, it disrupts the flow and confuses readers. Though these concepts are first introduced in fourth grade, seventh graders still need regular review as their sentence structures become more advanced and varied.
Tips for Parents and Teachers
- Read Aloud: Encourage students to read their draft sentences aloud. They will often naturally pause at a run-on or notice when a fragment feels unfinished.
- Find the Conjunctions: Practice identifying coordinating conjunctions (like and, but, so) to ensure they are paired with correct punctuation.
- Mix Up Sentence Lengths: Show students how combining fragments or splitting run-ons can actually make their writing more engaging.
With consistent practice, seventh graders can transition from basic sentence-level editing to polishing their overall writing voice.
