Editing for Clear Sentence Boundaries is a Grade 9 ELA writing resource that helps students strengthen sentence clarity, correct common sentence errors, and improve readability while preserving meaning. Through focused sentence editing practice, students explore how punctuation, sentence structure, modifier placement, and word choice contribute to effective writing.

What Students Will Learn

This resource focuses on practical editing skills that students can apply to their own writing. Learners will practise:

• Identifying and correcting run-on sentences, fragments, and comma splices.
• Recognizing how sentence boundaries help readers follow ideas clearly.
• Revising awkward phrases by moving modifiers closer to the words they describe.
• Removing needless repetition while keeping the original meaning.
• Applying editing strategies to improve sentence structure and readability.

Practice That Builds Editing Skills

Students begin with a reading passage explaining sentence editing for clarity, including definitions and examples of run-ons, comma splices, and fragments. They then apply these concepts through multiple-choice questions, true-or-false statements, short-answer tasks, a matching activity, and a cloze passage.

The activities address realistic editing decisions, such as correcting punctuation between independent clauses, completing sentence fragments, improving modifier placement, and removing unnecessary repetition. An extended-response essay asks students to explain how sentence editing improves readability and describe strategies for clearer writing.

• Student Worksheet: Structured practice covering sentence boundaries, punctuation, sentence structure, and clarity.
