Students rewrite three sentences that need a single missing comma each: "Because the power went out" before its main clause, "The library was closed" before the FANBOYS conjunction "so," and "When the bell rang" before the playground rush. Fill-in questions define introductory clauses, identify "because," "although," and "when" as common starters, and name "yet" as a coordinating conjunction in a compound sentence.
Short-answer prompts ask students to build their own "Although" sentence and explain how a comma helps a reader see where one independent clause ends and the next begins — exactly the move that turns choppy ideas into smooth, connected writing.

Comma Rules
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Because the power went out we had to use flashlights during dinner.
Rewrite: Because the power went out, we had to use flashlights during dinner.
2. Fix the sentence:
The library was closed so we walked to the bookstore instead.
Rewrite: The library was closed, so we walked to the bookstore instead.
3. Fix the sentence:
When the bell rang everyone rushed out the door to the playground.
Rewrite: When the bell rang, everyone rushed out the door to the playground.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. An introductory clause is a group of words that comes before the main part of a sentence.
2. A compound sentence joins two independent clauses with a comma and a conjunction.
3. Words like "because," "although," and "when" often begin an introductory clause.
4. In the sentence "She ran fast, yet she still missed the bus," the word "yet" is a coordinating conjunction.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Write a sentence that starts with an introductory clause beginning with "Although." Place the comma correctly.
Although it was snowing outside, we still walked to school that morning.
2. What is the difference between a simple sentence and a compound sentence? How do commas help?
A simple sentence has one independent clause, while a compound sentence has two independent clauses joined by a conjunction. A comma before the conjunction helps the reader see where one idea ends and the next begins.
