✂️ Sentence Fragments — Complete vs Incomplete

✅❌ Complete vs Fragment

✅
Complete Sentence
Has a subject and a predicate
"The cat sleeps on the bed."
❌
Fragment
Missing a subject or a predicate
"Sleeps on the bed." (no subject!)

📖 Grammar Guide

A sentence fragment is an incomplete thought — it is missing a subject or a predicate. "The dog" is a fragment (no predicate). "Runs fast" is a fragment (no subject). "The dog runs fast" is a complete sentence (subject + predicate). Hint: ask yourself "Is there someone doing something?" If you can answer "yes," it is a complete sentence.

✅❌ Complete or Fragment?

1. The cat sleeps. Complete / Frag
2. Runs to school. Complete / Frag
3. My best friend. Complete / Frag
4. She reads a book. Complete / Frag

✏️ Fix the Fragment

Add a subject or predicate to make each fragment a complete sentence.

5. Fragment: Went to the park. → went to the park.
6. Fragment: The big red ball. → The big red ball
7. Fragment: After school. →

✍️ Is It Complete?

About This Sentence Fragments Worksheet – Complete Sentences

This free printable sentence fragments worksheet worksheet reinforces grammar and word knowledge through application, not memorization. Students identify parts of speech, correct sentences, and apply rules in their own writing.

What Students Will Learn

Students learn how words work together in sentences — parts of speech, verb tenses, agreement, and sentence structure. Practicing these rules in context, rather than in isolation, helps students carry correct grammar into their own writing.

How Teachers Can Use This Worksheet

How Parents and Homeschoolers Can Use This Worksheet

Notice grammar in real life — read together and point out interesting sentences. Play word games that name parts of speech. When your child writes something, praise correct usage and gently model fixes for errors rather than over-correcting.

Skills Covered
