Language Arts: Sentence Fragments and Run-On Sentences

Identifying and fixing incomplete and overly long sentences

Language Arts - Grade 6-8

Instructions: Read each sentence carefully. Decide whether it is a complete sentence, a fragment, or a run-on sentence. Then revise it if needed.
  1. 1

    Read this group of words: Because the storm lasted all night. Is it a complete sentence, a fragment, or a run-on sentence? Rewrite it correctly if needed.

    Look for a complete thought with both a subject and a verb.

    This is a fragment because it begins with a subordinating word and does not complete the thought. One correct revision is: Because the storm lasted all night, the game was canceled.
  2. 2

    Read this sentence: Maya finished her homework she packed her backpack for school. Is it a complete sentence, a fragment, or a run-on sentence? Rewrite it correctly if needed.

    This is a run-on sentence because it joins two complete thoughts without proper punctuation or a conjunction. One correct revision is: Maya finished her homework, and she packed her backpack for school.
  3. 3

    Read this group of words: The dog under the porch. Is it a complete sentence, a fragment, or a run-on sentence? Rewrite it correctly if needed.

    Check whether the sentence tells what the subject does or is.

    This is a fragment because it does not express a complete thought and is missing a complete verb. One correct revision is: The dog hid under the porch.
  4. 4

    Read this sentence: I wanted to call my cousin, but I forgot my phone at home. Is it a complete sentence, a fragment, or a run-on sentence?

    A comma by itself cannot join two complete sentences.

    Read this group of words: After the movie ended. Is it a complete sentence, a fragment, or a run-on sentence? Rewrite it correctly if needed.

    Read this sentence: Jordan plays the violin, and his sister sings in the choir. Is it a complete sentence, a fragment, or a run-on sentence?

    Read this sentence: My little brother was tired he fell asleep on the couch. Is it a complete sentence, a fragment, or a run-on sentence? Rewrite it correctly if needed.
