Fix the Pieces: Sentence Fragments and Run-ons for Class 4 

This skill-building worksheet teaches Class 4 learners to spot, fix, and understand sentence fragments and run-on sentences. Through coloring tasks, story correction, matching, and rewriting activities, students sharpen their grammar by practicing how to form clear, complete sentences that make sense on their own. 

Why Fragments and Run-ons Matter in Grammar?

 Learning to recognize fragments and run-ons helps children: 
1. Write complete, grammatically correct thoughts. 
2. Understand how to punctuate and connect ideas clearly. 
3. Avoid common writing errors and confusing sentence construction. 
4. Gain confidence in storytelling and written expression. 

What’s Inside This Worksheet? 

This worksheet includes five scaffolded grammar tasks: 

🧠 Exercise 1 – F or R? 
Students label each sentence as a Fragment (F) or Run-on (R) to identify missing or jumbled structure. 

🎨 Exercise 2 – Colour by Sentence Type 
Learners color boxes blue (fragments), red (run-ons), or green (complete sentences) based on sentence type — a visual and hands-on check. 

🔍 Exercise 3 – Circle, Underline, Leave 
Students go through a paragraph and circle fragments, underline run-ons, and leave complete sentences untouched — building real-world editing skills. 

🔗 Exercise 4 – Match to Complete Sentences 
Using a matching game, students pair sentence halves to fix fragments and run-ons into complete, meaningful thoughts. 

✏️ Exercise 5 – Rewrite to Correct 
Learners are given incomplete or jumbled sentences and must rewrite them properly using correct punctuation, conjunctions, or added parts.
