A child writes: 'My big fluffy dog.' The teacher says this is not a complete sentence. The child argues it should be, because it says something about a dog. Who is right, and why?
AThe child is right — it includes a subject (dog), so it qualifies as a sentence
BThe teacher is right — the phrase has no verb, so it doesn't express what the dog does or is; it's an incomplete thought
CThe teacher is right — sentences must always begin with 'I' or 'The'
DThe child is right — verbs are optional in early writing
A complete sentence requires both a subject (who or what it's about) and a verb (what the subject does or is). 'My big fluffy dog' tells us what the subject is, but nothing about what it does or is — it leaves the reader waiting. Without a verb, there is no complete thought. The child's reasoning confuses having a subject with having a complete sentence.
Question 2 Multiple Choice
Why does every sentence begin with a capital letter and end with a period?
AIt's a decoration that makes writing look more formal and polished
BIt's an arbitrary rule that students must memorize without any underlying logic
CThese are signals to the reader: the capital marks where a new sentence begins, and the period marks where the thought is complete
DCapital letters are used for all important words, not just the start of sentences
Capitalization and end punctuation are reader signals, not arbitrary rules. Without them, a reader can't tell where one idea ends and another begins — especially in multi-sentence writing. Think of the capital as a door opening (new thought starting) and the period as the door closing (thought complete). These conventions exist to serve communication.
Question 3 True / False
A sentence that has a subject and several descriptive words about that subject is a complete sentence, even if it has no verb.
TTrue
FFalse
Answer: False
Descriptive words (adjectives, prepositional phrases) only add detail to the subject — they don't make the sentence complete. A sentence is complete only when it has both a subject and a verb. 'The tall, friendly, smiling teacher at the front of the room' is still a fragment because it tells us nothing about what the teacher does or is. Adding a verb ('smiled at us' or 'is kind') completes the thought.
Question 4 True / False
Saying a sentence aloud before writing it down is a useful strategy because it helps the writer hold the complete thought in working memory before committing it word by word to paper.
TTrue
FFalse
Answer: True
Writing a sentence requires holding the whole intended thought in mind while producing it one word at a time — a genuine working memory demand. Saying the sentence aloud first establishes the full thought before the writing process begins, reducing the chance of forgetting the end of the sentence mid-word. This strategy directly addresses one of the hardest parts of writing for young students.
Question 5 Short Answer
What two parts must every complete sentence have, and how can you check that your sentence includes both?
Think about your answer, then reveal below.
Model answer: Every complete sentence must have a subject (who or what the sentence is about) and a verb (what the subject does or is). To check, ask two questions: 'Who or what is this sentence about?' — that should give you the subject. 'What does it do, or what is it?' — that should give you the verb. If you can't answer both questions from your sentence, it's incomplete.
This two-question checklist is the most practical self-editing tool for young writers. It focuses attention on the structural requirements of a sentence rather than surface features like length or detail. A long sentence can still be a fragment; a short one like 'Dogs bark.' is complete.
