How to Use This Pack

Five worksheets that take turns through the activities. Pages 1 and 4: students circle whether each one is a sentence, a fragment, or a run-on. Pages 2 and 5: students write each run-on as two sentences. Page 3: students circle the words that make a fragment a complete sentence. Every answer is worked out from the sentences themselves, and the answer keys mark each one.

In the Classroom

Read sentences aloud with a pause at every period. A fragment leaves you waiting; a run-on leaves you out of breath.

At Home

Look for fragments in ads and headlines, then turn them into complete sentences together.

Tips for Success

  • A sentence needs a subject and a verb
  • A part with when or because needs more
  • Two sentences need a period or a comma and a conjunction
  • Check the answer key

Fragments and Run-On Sentences

4th Grade

Complete sentences, fragments that are missing a part, and run-ons that put two sentences together without the right punctuation. Students sort each one, fix run-ons, and finish fragments.
