- What is missing from Amir's sentence "My new soccer ball." to make it complete?
Answer: A predicate (what happens)
A complete sentence needs a subject (who or what) and a predicate (what happens). "My new soccer ball" already names a subject, but it never tells what the ball does or is, so it is a fragment. Adding a predicate fixes it, like "My new soccer ball rolled away" or "My new soccer ball is blue." The choice about needing a subject is wrong because the sentence already has one — the soccer ball. The choice about adding a second sentence is wrong because you don't need another idea; you need to finish this one. The choice about a comma and joining word is wrong because those connect two complete sentences, and here you only have one unfinished part. So the missing piece is a predicate that tells what happens.
- Fix this run-on: "Sofia finished her math she started reading." Which option correctly fixes the run-on sentence?
Answer: Sofia finished her math. She started reading.
This choice fixes the run-on by separating the two complete thoughts into two sentences with a period. The first choice only adds a comma, which creates a comma splice instead of fixing the run-on. The third choice adds a cause-and-effect word that was not part of the original meaning. The fourth choice joins the sentences in a confusing way and adds an idea that was not there before.
- Which sentence correctly fixes this comma splice: "I finished my homework, I watched TV."
Answer: I finished my homework. I watched TV.
The original sentence joins two complete ideas with only a comma, which is a comma splice. Splitting it into two separate sentences fixes the error correctly. Removing the comma without adding end punctuation just creates a run-on sentence. Dropping the subject before watched creates an incomplete idea, and turning the first part into a because clause loses the second idea entirely.
- Which choice fixes the sentence fragment: "Ran to the playground after lunch."?
Answer: Jamal ran to the playground after lunch.
The fragment is missing a subject, so we need to know who ran. Adding the name Jamal gives us both a subject and a verb, making a complete sentence that can stand on its own. One choice just reorders the words and adds "quickly," but it still never tells us who ran, so it stays a fragment. Another choice starts with "Because," which turns it into a dependent clause that leaves the reader waiting for the rest of the idea. The last choice starts with "When," which does the same thing: it sounds unfinished and cannot stand alone as a sentence. Only the choice naming Jamal fixes the fragment completely.
- Which sentence is written correctly with a subject and a predicate?
Answer: "Jamal hurried to his class."
The correct answer is "Jamal hurried to his class." It tells who the sentence is about (Jamal), tells what he did (hurried to his class), and makes complete sense all by itself. That means it has both a subject and a predicate.
"Because Jamal was late for the class" is tricky because it does have a subject and a verb. But the word "Because" leaves you waiting to find out what happened, so it is not a complete thought yet.
"Ran quickly to the crowded bus stop" tells what happened, but it never says who ran. With no subject, it is a fragment.
"The big red backpack by the door" names a thing, but it never tells you what the backpack does or is. With no predicate, it is a fragment too.
To check any sentence: find who or what it is about, find what happens (the verb), then ask, "Does this make sense on its own?" Only "Jamal hurried to his class" passes all three tests.
- Is "The books on the shelf." a complete sentence, fragment, or run-on?
Answer: Fragment, because it is missing a verb that tells what happens
The correct answer is that this is a fragment. A complete sentence needs a subject and a predicate with a verb. Here we have a subject, "The books," and a describing phrase, "on the shelf," but no verb telling us what the books do or are. Without that, the idea is not finished, so it is a fragment. You could fix it by adding a verb: "The books on the shelf are dusty."
"Complete sentence" is wrong because a group of words with a subject still is not complete if it has no verb telling what happens. "Run-on" is wrong because a run-on jams two whole sentences together, but here there is only one incomplete idea, not two. "Question" is wrong because the words do not ask anything and there is no question mark. Only a fragment matches: one piece of a sentence that is missing a key part.
- Which best corrects Carlos's run-on: "I like drawing it helps me relax."
Answer: I like drawing; it helps me relax.
The original sentence is a run-on: two complete thoughts, "I like drawing" and "it helps me relax," are jammed together with no punctuation. Using a semicolon between the two related thoughts fixes it, because a semicolon can join two complete sentences that go together. "I like drawing it really helps me relax" just adds the word "really" but still runs the two thoughts together with no punctuation, so it is still a run-on. "I like drawing, it helps me relax" tries to fix it with only a comma, but a comma alone cannot join two complete sentences—that is a comma splice. "Because I like drawing it helps me relax" adds a word but makes the first part depend on the second and leaves the thoughts joined without correct punctuation, so it is not fixed either. Only the semicolon separates the two complete thoughts correctly.
- Which choice correctly fixes this run-on sentence: "The bell rang we lined up."?
Answer: The bell rang. We lined up.
The correct answer fixes the run-on by splitting it into two complete sentences with a period. Choice A is wrong because a comma alone cannot join two complete sentences; this is called a comma splice. Choice C is wrong because it starts a dependent clause but leaves out the comma that should follow it. Choice D is wrong because it needs a comma before "and" to correctly join the two complete thoughts.
- Read: "The puppy in Amir's yard." What is missing to make it complete?
Answer: A predicate (what the puppy does or is)
"The puppy in Amir's yard" is a fragment. It names who it is about — the puppy — but it never tells what the puppy does or is. That missing action or state is the predicate, so a predicate is exactly what makes this sentence complete (for example, "The puppy in Amir's yard barks").
Saying it needs another subject is wrong: the group of words already has a subject, "The puppy." The phrase "in Amir's yard" just tells where the puppy is, so adding a second naming part would not fix anything.
Adding a second thought about what happens next is also wrong. A fragment isn't missing a whole extra idea — it is missing one part of the single idea it already started.
A comma is wrong too. A pause mark cannot supply the missing action word, and "The puppy, in Amir's yard" is still a fragment. Every complete sentence needs a subject and a predicate, and here only the predicate is missing.
- Read this sentence: "After the game ended." Is it a fragment, run-on, or complete sentence?
Answer: It is a fragment that does not finish one whole thought.
The group of words "After the game ended" is a fragment because the word "After" makes you expect more, and the thought is never finished. A fragment is a piece of a sentence that cannot stand on its own. It is not a complete sentence, because a complete sentence must share one whole, finished thought, and this one leaves you waiting to hear what happened after the game ended. It is not a run-on, because a run-on has too many complete thoughts crammed together, while this group has too few. It is not a complex sentence, because a complex sentence needs a full main idea added to the extra part, and here the main idea is missing.
- Which sentence is a run-on that needs a period or joining word?
Answer: Yuki packed her lunch she ate it outside at recess.
The run-on is "Yuki packed her lunch she ate it outside at recess." It jams two complete sentences together with no period or joining word. You could fix it by adding a period after "lunch" or a word like "and." The sentence about packing lunch in a bright blue bag is already complete and correctly punctuated, so it is not a run-on. The choice about the noisy school cafeteria next to the gym is a fragment: it names something but has no action word telling what happened, so it is not a complete sentence at all. The choice starting with "Because it was so cold and windy" is also a fragment, because "Because" leaves the idea unfinished and you are left waiting to hear what happened. Only one choice has two full sentences run together, and that is the run-on you need to fix.
- Is "Because it was windy at recess." a complete sentence, fragment, or run-on?
Answer: Fragment
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 - dependent clause fragments start with words like because, when, if, although but don't tell us what happened. In this example, 'Because it was windy at recess' is a fragment. It is a dependent clause that doesn't express a complete thought - the word 'because' makes us expect to hear what happened as a result of the wind, but that information is missing. Choice C is correct because it correctly identifies this as a fragment - specifically a dependent clause fragment that needs a main clause to complete the thought. Choice B represents a common error where students think any clause with subject and verb is complete, which occurs when students don't recognize that dependent words (because, when, if, although) make thoughts incomplete. 'Because it was windy at recess' has a subject (it) and verb (was), but the word 'because' makes it dependent - it needs completion like 'Because it was windy at recess, we played inside.' To help students: Teach that dependent words (because, when, if, although, since) create incomplete thoughts that need main clauses. Practice completing dependent clauses - 'Because it rained...' needs 'we stayed inside' or similar. Common fragments include dependent clause alone (starts with because/when/if but doesn't tell what happened). Watch for: not recognizing dependent words make incomplete thoughts, thinking any group with subject+verb is complete, and confusing dependent clauses that sound natural in speech with complete sentences in writing.
- In Jamal's journal, is "Ran to the bus stop." a fragment, run-on, or complete sentence?
Answer: Fragment
Fragment is correct because "Ran to the bus stop" has no subject telling who ran, so it cannot stand alone as a complete thought. It is not a complete sentence because it is missing a subject. It is not a run-on because a run-on joins too many complete thoughts together, not too few. It is not a compound sentence because it does not join two complete sentences with a conjunction.
- Which sentence is written correctly for Sofia's book report?
Answer: The story was thrilling, and I read it every night.
A correct sentence can join two complete ideas with a comma and a joining word like and. The sentence that says the story was thrilling, and I read it every night does this the right way, so it is correct. The sentence about the story being exciting, it was fun to read every night has two complete ideas but glues them with only a comma, which is a comma splice. The sentence about the story having a brave girl, her big dog helped her too makes the same comma-splice mistake by joining two full ideas with just a comma. The sentence that says the story was thrilling, I read it every night also uses only a comma between two complete ideas, so it is a comma splice too. Each wrong choice needs a joining word after the comma, or it could be split into two sentences. Only one choice fixes the run-on the correct way.
- What is missing from this fragment: "Is my favorite game."
Answer: A subject (who or what)
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). 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. In this fragment, 'Is my favorite game' is missing a subject - we don't know what is the favorite game. Choice A is correct because it identifies that a subject (who or what) is missing from this fragment. The fragment has a predicate 'is my favorite game' but no subject to tell us what thing is the favorite game. Choice B represents a common misconception where students think fragments need punctuation fixes, which occurs when students confuse fragment problems with punctuation problems. Adding a comma won't help 'Is my favorite game' - it needs a subject like 'Chess is my favorite game' or 'Soccer is my favorite game.' Fragments are fixed by adding missing parts (subject, predicate, or completion), not by adding 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?' For this fragment, step 1 fails - no subject found. Common fragments include missing subject ('Went to school' - who went?), and these often start with a verb. Watch for: thinking punctuation fixes fragments, not recognizing when subject is missing especially when sentence starts with verb, and confusing different types of sentence errors (fragments need missing parts, not punctuation).
- Which best corrects this comma splice: "Maya drew a cat, Marcus colored it."
Answer: Maya drew a cat. Marcus colored it.
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 RUN-ON is two complete sentences incorrectly joined together - a comma splice uses just a comma between complete sentences, which is incorrect. In this example, 'Maya drew a cat, Marcus colored it' is a comma splice run-on. Two complete sentences ('Maya drew a cat' and 'Marcus colored it') are joined with only a comma. Choice B is correct because it properly separates the two sentences with a period: 'Maya drew a cat. Marcus colored it.' Choice C represents the original comma splice error, which occurs when students think a comma alone can join two complete sentences. A comma by itself cannot join two complete sentences - you need either a period to separate them or a comma plus a conjunction (and, but, so, or). Choice D also corrects the run-on by making the first part dependent with 'Because,' creating one complex sentence. To help students: Teach to read slowly and listen for two complete thoughts - if joined by only a comma, it's a comma splice run-on. For run-ons, teach three correction strategies: separate with period, join with comma+conjunction, or use dependent word to make one part dependent. Common run-ons include comma splice (comma alone between sentences). Watch for: using comma alone to join sentences (need comma + conjunction like 'and'), thinking any sentence with a comma between clauses is correct, and not recognizing that two subject-predicate combinations usually mean two sentences.
- Is "Yuki read a book and wrote a summary." a complete sentence, fragment, or run-on?
Answer: Complete sentence
This sentence has a subject, Yuki, and two actions, read and wrote, joined correctly by the word and, so it is a complete sentence with one clear thought. It is not a fragment, because a fragment is missing a subject or a verb, and this one has both. It is not a run-on, because a run-on jams two full sentences together without the right punctuation or joining word, but here the actions are joined properly with and. It is not a comma splice, because a comma splice joins two full sentences using only a comma, and this sentence has no comma joining anything.
- Which sentence is written correctly for Maya's journal entry about art class?
Answer: Maya painted a sunset during art class.
The correct answer is "Maya painted a sunset during art class." It has a subject (Maya), tells what she did (painted a sunset during art class), and makes complete sense on its own, so it is a complete sentence. "Because Maya used bright colors in her painting" is a fragment: the word "because" leaves you waiting to hear what happened, so the thought is not finished. "Painted a bright sunset during art class" is also a fragment because it is missing a subject—you cannot tell who painted. "Maya painted a sunset she showed it to her teacher" is a run-on: it jams two complete sentences together without the right punctuation. To test any sentence, find the subject, find the verb, and ask, "Does this make sense by itself?" Only the correct choice passes all three checks.
- Which choice fixes the sentence fragment: "Ran to the playground after lunch."?
Answer: He ran to the playground after lunch.
Choice B is correct because it adds a subject, making it a complete sentence. Choice A repeats the original fragment, which still has no subject. Choice C adds "because," turning it into a dependent clause that cannot stand alone. Choice D joins two complete sentences with only a comma, which creates a run-on.
- Which sentence correctly fixes the fragment "Played basketball at recess."?
Answer: Marcus played basketball at recess.
A sentence fragment is missing a subject or does not express a complete thought. Adding the subject "Marcus" fixes this, making "Marcus played basketball at recess." a complete sentence. The other choices still lack a clear subject and complete thought, since they add a conjunction, a dependent clause, or a participial phrase instead of fixing the fragment.
