Learning objectives

Distinguish a complete sentence from a fragment.
Identify subjects, complete verbs, and complete thoughts.
Recognize missing-subject, missing-verb, and dependent-word fragments.
Repair fragments for clear formal writing.

Key concepts

Sentence: subject + complete verb + complete thought.
Fragment: one or more essential parts are missing.
Dependent clue words: because, although, when, if, while.

Suggested experiments

Remove the subject and watch one diagnostic light turn off.
Select “dancing” and repair the missing helping verb.
Add “although” and observe a complete thought become dependent.
Click characters and word cards to focus and inspect them.

Questions for exploration

Can a word group contain both a subject and verb but still be a fragment? When might an author use a fragment deliberately?
