Stronger Sentences, Clearer Ideas: Simple and Compound Sentences for Grade 4 

This Grade 4 English worksheet helps learners understand and practise simple and compound sentences in a clear, structured way. Through noun–verb identification, multiple-choice questions, sentence rewriting, a connected passage, and paragraph writing, students learn how to express single ideas in simple sentences and join related ideas using conjunctions in compound sentences. The content is classroom-friendly and gently increases rigour so that learners can apply these patterns in their own reading and writing. :contentReference[oaicite:0]{index=0} 

Why Simple & Compound Sentences Matter in Grammar? 

1. They help students express ideas with variety instead of using the same short pattern every time. 
2. Correct use of conjunctions like and, but, or improves sentence flow and clarity. 
3. Understanding how ideas join into longer sentences supports better reading comprehension. 
4. These skills prepare learners for more advanced sentence structures in higher grades. 

What’s Inside This Worksheet? 

Exercise 1 – Underline the Noun and Circle the Verb 
Students underline the naming word (noun) and circle the action word (verb) in each of ten sentences about everyday school and home situations. This reinforces sentence structure before they move on to types of sentences. 

Exercise 2 – Multiple Choice: Simple or Compound Sentences 
Learners read ten sets of options and choose which one matches the instruction, such as “This sentence is simple” or “This sentence is compound.” They observe how conjunctions (and, but, or) link ideas in compound sentences. 

Exercise 3 – Rewrite as Simple or Compound 
Students rewrite given sentences as either simple or compound, according to the instruction beside each question. They learn when a sentence is already in the correct form and when it must be changed. 

Exercise 4 – Fill in the Blanks (Healthy Food Project) 
Learners complete a passage about a class project on healthy food by filling blanks with suitable conjunctions and introductory words. This shows how simple and compound sentences appear in a meaningful paragraph. 

Exercise 5 – Paragraph Writing 
Students write a short paragraph describing how they help at home, using both simple and compound sentences. This encourages them to apply the concepts independently in their own writing.
