Read this sentence: "Emma likes art, she paints after dinner." What is it?
Fragment
Question sentence
Complete sentence
Run-on (comma splice)
Explanation
This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete) and run-ons (two sentences incorrectly joined). A complete sentence has three parts: a SUBJECT (who/what it's about), a PREDICATE (what the subject does/is - includes a verb), and a COMPLETE THOUGHT (makes sense alone). A FRAGMENT is missing one of these parts - common types include missing subject ('Ran to school' - who ran?), missing predicate ('The big dog' - what about the dog?), or dependent clause alone ('Because it rained' - what happened?). A RUN-ON is two complete sentences incorrectly joined together - either with just a comma (comma splice: 'I ran, she walked') or with no punctuation (fused sentence: 'I ran she walked'). In this example, 'Emma likes art, she paints after dinner' is a run-on. Two complete sentences 'Emma likes art' and 'she paints after dinner' are joined with only a comma, creating a comma splice. Choice B is correct because it correctly identifies this as a run-on (comma splice) because two sentences are incorrectly joined. Choice C represents a wrong identification, which occurs when students think any sentence with a comma is complete. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?' If missing any part = fragment. For run-ons, teach to read slowly and listen for two complete thoughts running together - if yes, need period or comma+conjunction (and, but, so, or) to join. Practice identifying subjects and predicates in sentences. Common fragments: Missing subject ('Went to school' - who went?), Missing predicate ('The small bird' - what about it?), Dependent clause alone (starts with because/when/if but doesn't tell what happened). Common run-ons: Comma splice (comma alone between sentences - need period or add conjunction), Fused sentence (no punctuation between sentences). Watch for: thinking 'The big brown dog' is complete (missing predicate/verb), thinking any long group of words is complete sentence, using comma alone to join sentences (need comma + conjunction like 'and'), not recognizing dependent words (because, when, if, although) make incomplete thoughts that need main clause. Teach correction strategies: Fragments - add what's missing; Run-ons - separate with period OR join with comma+conjunction OR use dependent word.

In this example, 'After the game ended' is a fragment. It is missing completion - the dependent clause starting with 'after' doesn't tell us what happened because it can't stand alone as a complete thought. Choice C is correct because it correctly identifies this as a fragment because it's missing a main clause to complete the thought, such as 'After the game ended, we went home.' Choice A represents a wrong identification, which occurs when students confuse dependent clauses with complete sentences. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?'

In this example, 'The puppy with the red collar' is a fragment. It is missing a predicate - we don't know what the puppy does or is. Choice A is correct because it identifies the missing predicate (what the puppy does). Choice B represents a misconception, which occurs when students think a descriptive phrase has a verb but it's missing the action.

A RUN-ON is two complete sentences incorrectly joined together - either with just a comma (comma splice: 'I ran, she walked') or with no punctuation (fused sentence: 'I ran she walked'). In this example, the question asks to identify which option is a complete sentence with both subject and predicate. Choice D 'Jamal ran to the library after school' is a complete sentence. It has a subject 'Jamal', predicate 'ran', and expresses a complete thought. Choice A is incorrect because it is a fragment missing a subject - we don't know who ran.

Which sentence is written correctly for Maya’s journal entry about art class?
Painted a sunset during art class.
Maya painted a sunset she showed it to her teacher.
Because Maya used bright colors.
Maya painted a sunset during art class.
Explanation
This question tests CCSS.L.4.1.f: producing complete sentences and recognizing and correcting inappropriate fragments and run-ons. Students must identify complete sentences (subject + predicate + complete thought) versus fragments (incomplete) and run-ons (two sentences incorrectly joined). A complete sentence has three parts: a SUBJECT (who/what it's about), a PREDICATE (what the subject does/is - includes a verb), and a COMPLETE THOUGHT (makes sense alone). A FRAGMENT is missing one of these parts, while a RUN-ON is two complete sentences incorrectly joined together. In evaluating these options, we need to find the complete, correctly written sentence. Choice B is correct because 'Maya painted a sunset during art class' has a subject (Maya), predicate (painted a sunset during art class), and expresses a complete thought - it stands alone and makes sense. Choice C represents a fragment error, which occurs when students forget to include the subject. 'Painted a sunset during art class' is missing the subject - we don't know who painted. Choice A 'Because Maya used bright colors' is a dependent clause fragment - the word 'because' makes it incomplete, leaving us wondering what happened because she used bright colors. Choice D 'Maya painted a sunset she showed it to her teacher' is a run-on - two complete sentences joined without proper punctuation. To help students: Teach the 'complete sentence test' - (1) Find subject (who/what it's about), (2) Find predicate (what happens - needs verb), (3) Ask 'Does it make sense alone?' If missing any part = fragment. For run-ons, teach to read slowly and listen for two complete thoughts running together. Common errors include dependent clause fragments (starts with because/when/if), missing subject fragments, and fused sentences (no punctuation between complete thoughts). Watch for: thinking dependent clauses like 'Because Maya used bright colors' are complete, not recognizing run-ons when sentences flow together, and choosing fragments that sound natural in speech but are incomplete in writing.
