This question tests CCSS.L.5.2.b: using a comma to separate an introductory element from the rest of the sentence. An introductory element comes at the beginning of a sentence and provides context about when, where, why, how, or under what conditions the main action occurs. A comma is placed immediately after the introductory element to separate it from the main clause. Types include: single words (Yesterday, However), prepositional phrases (In the morning, After school), and dependent clauses (When it rains, If you finish). This sentence begins with a prepositional phrase: 'During lunch'. This provides time context for the main sentence. The main clause begins with 'Sofia traded'. Choice C is correct because it places the comma immediately after the introductory element 'During lunch,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'During lunch, Sofia traded her apple for a granola bar.' Choice A represents missing comma error. This error makes sentence harder to read and obscures where introduction ends. Students make this error when they don't recognize introductory elements. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: prepositional phrases starting sentences (In the morning, After school, During lunch). Remember: even SHORT introductory phrases should have comma in 5th grade writing.

This sentence begins with a prepositional phrase: 'In the library'. This provides location context for the main sentence. The main clause begins with 'Maya found'.

The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'In the library, Maya found a book about planets.' Choice B represents comma in wrong place error. This error breaks the prepositional phrase incorrectly by placing comma after 'In' instead of after the complete phrase. Students make this error when they confuse with other comma uses. To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns: single transition words (However, Therefore), time/place words (Yesterday, Outside), prepositional phrases starting sentences (In the morning, After school, Under the tree). Remember: even SHORT introductory phrases should have comma in 5th grade writing.

To help students: Teach them to identify introductory elements by asking 'What comes before the main idea?' or 'What gives context for the sentence?' Practice underlining or bracketing the introductory element, then placing comma after it before the main clause. Create formula: [Introductory element], [main clause]. Common introductory patterns include participial phrases that describe how the action is performed. Use hand motion: introduction (hand up), comma (pause), main clause (hand down).
