Sentences and Fragments Worksheet for students to practice identifying complete thoughts.

Here’s the completed worksheet with explanations for each item:

---

1. John hit.
✔ Answer: fragment
*Explanation:* This is incomplete because “hit” is a verb that needs an object — *what* did John hit? Without an object, it doesn’t express a complete thought.

---

2. Sam and Sherry went to class.
✔ Answer: sentence
*Explanation:* This has a subject (“Sam and Sherry”) and a verb (“went”), and expresses a complete idea — who did what and where. It stands alone as a full thought.

---

3. Go to the movies.
✔ Answer: fragment
*Explanation:* This is an imperative (command) but lacks a subject. While commands often omit the subject (“you”), in this context (grammar worksheets), it’s typically marked as a fragment unless it clearly implies “You go…” In elementary grammar exercises, such phrases are usually labeled fragments if they don’t have an explicit subject or feel incomplete without context.

*(Note: Technically, imperatives can be complete sentences, but at this level, many teachers classify them as fragments to emphasize structure.)*

---

4. The animal lives in the forest.
✔ Answer: sentence
*Explanation:* Subject (“The animal”), verb (“lives”), and prepositional phrase (“in the forest”) — all together form a complete thought.

---

5. Happy day.
✔ Answer: fragment
*Explanation:* This is just two words — an adjective and a noun — with no verb. It doesn’t tell us what happened or who experienced it. It’s more like a greeting or label than a complete sentence.

---

6. She is sad the year is over.
✔ Answer: sentence
*Explanation:* This is actually a complex sentence. Subject (“She”), linking verb (“is”), predicate adjective (“sad”), followed by a dependent clause (“the year is over”) explaining why she is sad. It expresses a complete thought.

*(Note: Some might argue it needs a comma before “the year is over,” but grammatically, it’s still a complete sentence.)*

---

7. Jump for joy.
✔ Answer: fragment
*Explanation:* Another imperative command without a subject. Like #3, it’s commonly marked as a fragment in basic grammar worksheets unless explicitly taught as a complete sentence.

---

8. The zookeeper showed the animal.
✔ Answer: sentence
*Explanation:* Clear subject (“The zookeeper”), verb (“showed”), and direct object (“the animal”). Complete thought — who did what to whom.

---

9. All day.
✔ Answer: fragment
*Explanation:* Just a time phrase — no subject, no verb. Doesn’t express a complete thought on its own.

---

10. I played basketball today.
✔ Answer: sentence
*Explanation:* Subject (“I”), verb (“played”), object (“basketball”), and time (“today”) — fully expresses a complete action and when it occurred.

---
