When this is useful
Identify sentence fragments
Clear examples give students focused practice telling a complete sentence apart from a fragment.
Fix missing subjects and predicates
Students add who or what is missing, or tell what the subject did, to complete a sentence.
Dependent-clause and phrase fragments
Show that a clause beginning with because or a phrase like under the tree cannot stand alone.
Choose the best correction
The choose format gives one complete-sentence fix beside three repairs that stay incomplete.
ELL and language support
Identify and choose formats help multilingual learners hear when an idea is finished.
Your own sentences
Paste your own fragments so the editing practice matches your class writing or a recent lesson.
Examples to try
An identify-the-fragment worksheet
Use the identify format so students label each group of words as complete or a fragment.
A choose-the-best-correction worksheet
Use the choose format so students pick the one repair that makes a complete sentence.
An add-a-subject worksheet
Use the add-a-subject format so students supply who or what is missing from the fragment.
An add-a-predicate worksheet
Use the add-a-predicate format so students tell what the subject did or was.
A complete-the-thought worksheet
Use the complete-the-thought format for dependent-clause and phrase fragments.
A worksheet from your own sentences
Paste fragments, or simple text = missing_subject lines, to match your class.
Tips for better results
Check for a subject and a verb
Remind students that a complete sentence needs a subject, a predicate, and a finished thought.
Watch for opening subordinators
A group of words that starts with because, when, or although is usually a dependent-clause fragment.
Read it aloud
If a group of words leaves you waiting for more, it is probably a fragment, not a sentence.
Start with subjects and predicates
Beginner difficulty keeps practice on adding the missing subject or the missing predicate.
Print the answer key separately
The PDF puts the answer key on its own page, so you can keep it apart from the student copy.
Pair it with grammar tools
Follow with a run-on sentences worksheet or a compound and complex sentences worksheet for more sentence practice.
How the sentence fragments worksheet generator works
Built-in worksheets use original, classroom-safe sentences written for this tool. Each item is one clear type — a complete sentence, or a specific kind of fragment: missing a subject, missing a predicate, a dependent clause, a phrase, or a detail — paired with the part it is missing, a single best correction, and a short explanation, so the answer key is always defensible. A complete sentence has a subject, a predicate, and a complete thought; a fragment is missing one of those, so each example fits one label clearly and there is never more than one right answer.
Identify questions have one deterministic answer, and choose-the-best-correction questions place the one complete-sentence fix beside three hand-picked repairs that each stay incomplete, so there is exactly one correct answer with no duplicate choices. The rewrite, add-a-subject, add-a-predicate, and complete-the-thought formats give students room to write, with the answer key showing a suggested complete sentence. Custom items let you bring your own; the type and missing part are normalized or safely inferred from clear structure only, and when a custom item lacks enough data it uses a teacher-check sample instead of inventing one.
