Printable worksheet for students to practice identifying complete and incomplete sentences, with instructions to place a star next to complete sentences and an X next to incomplete ones.

To solve the problem, we need to determine whether each sentence is complete or incomplete. A complete sentence must have a subject and a predicate and express a complete thought. An incomplete sentence (also known as a fragment) lacks either a subject, a predicate, or does not express a complete thought.

Let's analyze each sentence:

1. The cat likes to play.
- Subject: The cat
- Predicate: likes to play
- Complete thought: Yes
- Conclusion: Complete sentence

2. I can find.
- Subject: I
- Predicate: can find
- Complete thought: No (What can you find? This is incomplete.)
- Conclusion: Incomplete sentence

3. Cute, little kittens.
- Subject: Cute, little kittens
- Predicate: None (This is just a description without an action or thought.)
- Complete thought: No
- Conclusion: Incomplete sentence

4. I like to go to the library.
- Subject: I
- Predicate: like to go to the library
- Complete thought: Yes
- Conclusion: Complete sentence

5. We can bake cookies after school.
- Subject: We
- Predicate: can bake cookies after school
- Complete thought: Yes
- Conclusion: Complete sentence

6. He rode his bike to the park.
- Subject: He
- Predicate: rode his bike to the park
- Complete thought: Yes
- Conclusion: Complete sentence

7. Brings cupcakes to school.
- Subject: None (Who brings cupcakes?)
- Predicate: Brings cupcakes to school
- Complete thought: No
- Conclusion: Incomplete sentence

8. We like to go to the beach.
- Subject: We
- Predicate: like to go to the beach
- Complete thought: Yes
- Conclusion: Complete sentence

9. She fell down and hurt.
- Subject: She
- Predicate: fell down and hurt
- Complete thought: Yes
- Conclusion: Complete sentence

10. They found a baby bird.
- Subject: They
- Predicate: found a baby bird
- Complete thought: Yes
- Conclusion: Complete sentence

11. My teacher is nice.
- Subject: My teacher
- Predicate: is nice
- Complete thought: Yes
- Conclusion: Complete sentence

12. This year.
- Subject: None
- Predicate: None
- Complete thought: No
- Conclusion: Incomplete sentence

Final Answer:

- Complete sentences: ✩
- Incomplete sentences: X
