This Grade 4 English grammar worksheet focuses on Conjunctions such as but, so, if, or, when, because, yet, and, although, and until. Conjunctions are essential linking words that help students join ideas, show contrast, express conditions, and explain reasons in complete sentences.
Designed for upper primary learners, this worksheet builds strong sentence construction skills through structured activities including fill in the blanks, true or false, multiple choice questions, sentence correction, and independent writing tasks. Each section strengthens students’ understanding of how conjunctions connect clauses meaningfully.
The fill-in-the-blanks activity improves contextual usage. The true or false section reinforces grammar rules. Multiple choice questions help students select the most appropriate conjunction. The correction exercise develops editing skills by replacing incorrect conjunctions. Finally, a writing task encourages students to apply conjunctions independently in their own sentences.
Conjunctions are important because:
1. They connect words, phrases, and clauses smoothly.
2. They help express contrast, reason, choice, time, and condition.
3. They improve sentence fluency and logical flow.
4. They are commonly tested in Grade 4 CBSE English grammar sections.
