Sentence Structure: Subjects, Predicates, and Fragments

Malik, Brianna, and Lucy are writing instructions for a coding club game. Help them make every sentence clear and complete. A complete sentence has a subject and a predicate, expresses a complete thought, and ends with appropriate punctuation. In Part 2, identify the complete subject and complete predicate.

Sentence or Fragment?

For each item, choose whether the words express a complete thought or leave an idea unfinished.

1.Brianna tested the game before the club meeting.
  • Full sentence
  • Fragment
2.Under the desk beside the computer.
  • Full sentence
  • Fragment
3.The blue robot followed Malik across the screen.
  • Full sentence
  • Fragment
4.Because Lucy forgot to save her code.
  • Full sentence
  • Fragment

Find the Subject and Predicate

Write the complete subject and complete predicate for each sentence. The subject tells who or what the sentence is about; the predicate tells what the subject does or is.

5.The two new players joined the coding club.
6.Malik and Brianna carefully checked each command.

Repair the Code Notes

Rewrite each fragment so it expresses a complete thought. Many answers are possible; include a subject, a predicate, and correct end punctuation.

7.Fragment: Ran the program again after lunch.
8.Fragment: The game with the spinning planets.
9.Fragment: When Lucy pressed the green button.

Build and Improve

Use what you know about sentence structure to make the club's instructions clearer.

10.Combine these ideas into one sentence using because. Show that the program froze first and caused Brianna to restart the computer: “Brianna restarted the computer. The program froze.”
11.Write one sentence about a game you would make for coding club. Then label its complete subject and complete predicate.
