Product description

From the author

Introduction

This set of 9 grammar worksheets helps students learn, practice, and master compound sentences in a step-by-step approach. The activities move from identifying compound sentences to combining simple ones using coordinating conjunctions (and, but, or, so).

Learners also practice selecting the correct conjunction, correcting punctuation, expanding sentences, and revising for clarity. The varied formats—identification, conjunction selection, editing, and short writing — make grammar practice engaging and effective. By the end, students confidently use commas and conjunctions to create smoother, more complex writing.

What distinguishes the four sentence-combining pages from one another?

Each page practices joining two short sentences with one specific conjunction in turn (and, then but, then or, then so), before later pages mix multiple conjunctions and add correct punctuation.
