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 dependent clause: 'If you finish your homework'. This provides condition context for the main sentence. The main clause begins with 'you can play'. Choice A is correct because it places the comma immediately after the introductory element 'If you finish your homework,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'If you finish your homework, you can play a board game.' Choice D 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, especially dependent clauses. 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), dependent clauses (When..., If..., Because..., Although...). Have students identify the subject and verb of main clause - comma goes before these. Remember: even SHORT introductory phrases should have comma in 5th grade writing.

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.

This sentence begins with a prepositional phrase: 'In the morning'. This provides time context for the main sentence. The main clause begins with 'Maya feeds'. Choice A is correct because it places the comma immediately after the introductory element 'In the morning,', separating it from the main clause. The comma signals the shift from introductory context to the main idea, making the sentence structure clear: 'In the morning, main clause.' Choice B represents comma in wrong place error - placing comma within the prepositional phrase after just the preposition. This error breaks the prepositional phrase incorrectly. Students make this error when they put comma after first word only when phrase is longer. 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), dependent clauses (When..., If..., Because..., Although...). Watch for: omitting comma entirely (most common), placing comma within introductory element instead of after it, confusing introductory commas with series commas, and putting comma after first word only when phrase is longer.
