Commas in Introductory Clauses: Grammar Practice for Grade 5

Title: Commas After Introductory Clauses: Grade 5 English Grammar Worksheet 

Have you ever written a sentence like “When I arrived she left” and wondered if you needed a comma? You do! A comma is used after an introductory clause. Introductory clauses come at the beginning of a sentence before the main clause. They often start with words like “when,” “if,” “because,” “although,” “while,” “before,” “after,” “as,” “since,” “until,” and “whereas.” The comma helps separate the introductory clause from the main clause, making the sentence easier to read. In Grade 5, learning to use commas correctly after introductory clauses will make your writing clearer and more professional. This Grade 5 English grammar worksheet on editing commas in introductory clauses will teach you the rule and help you practice.

What Is the Topic? 

The topic of this worksheet is Editing: Incorrect Use of Commas in Introductory Clauses. An introductory clause is a group of words that comes at the beginning of a sentence before the main clause. It often tells when, why, or under what condition something happened. A comma is used after an introductory clause to separate it from the main clause. For example: “When I arrived, she left.” (comma after “arrived”) “After the rain stopped, we went outside.” (comma after “stopped”) “If you study hard, you will succeed.” (comma after “hard”) “Although it was late, we continued working.” (comma after “late”) “Because it was raining, we stayed indoors.” (comma after “raining”) “While she was reading, he was cooking.” (comma after “reading”) “When the teacher entered, everyone stood up.” (comma after “entered”) Introductory clauses can begin with words like “when,” “if,” “because,” “although,” “while,” “before,” “after,” “as,” “since,” and “whereas.” Without the comma, sentences can be confusing or hard to read. Understanding this rule helps you write clear, correct sentences.

Original paragraph with missing commas: 

When I reached the playground I saw my friends already playing cricket near the boundary. After a few minutes we divided ourselves into teams and started the match. Although it was very hot we continued playing with great excitement and energy. When the teacher called us from a distance we didn’t hear her at first. Because we were busy playing we ignored the bell for a while. After realizing the time we quickly gathered our things and walked toward the bench. While we were drinking water we talked about the best moments of the game. Before leaving the ground we thanked our coach for guiding us. When we reached the classroom we were still discussing the match. After the final bell rang we went home feeling happy and tired after such a fun day. 

Corrected paragraph:

Although it was very hot, we continued playing with great excitement and energy. When the teacher called us from a distance, we didn’t hear her at first.

Quick learning tip: If a sentence starts with a word like “when,” “if,” “because,” “although,” “while,” “before,” or “after,” and that word begins a clause that comes before the main part of the sentence, put a comma after that clause.

Why Is It Important to Learn This? 

Learning about commas in introductory clauses is important for several reasons. First, a comma is used after an introductory clause. Without it, sentences can be confusing: “When I arrived she left” is harder to read than “When I arrived, she left.” Second, the comma helps separate the introductory clause from the main clause. This makes the sentence’s meaning clear. Third, introductory clauses often begin with words like “when,” “if,” “because,” “although,” “while,” “before,” and “after.” Recognizing these words helps you know when a comma is needed. Fourth, this topic is tested in grammar exams where you may be asked to add missing commas or correct errors. Finally, using commas correctly after introductory clauses makes your writing look professional and easy to read.

Where Will This Knowledge Help You? 

Knowledge of commas in introductory clauses will help you in many academic and real-life situations: 

1. Grammar exams and language tests – Many questions ask you to add commas after introductory clauses. This worksheet directly prepares you for those questions. 

2. Writing essays and stories – Using commas correctly after introductory clauses makes your writing smoother and easier to read. “After the rain stopped, we went outside” is clearer than “After the rain stopped we went outside.” 

3. Avoiding run-on sentences – The comma after an introductory clause signals a pause, helping readers follow your meaning. 

4. Understanding what you read – When you see a comma after a word like “when” or “if,” you know that the introductory clause is ending. 

5. Improving sentence variety – Using introductory clauses (and commas) allows you to start sentences in different ways, making your writing more interesting.

Important Tips and Tricks 

Here are important tips and tricks based directly on this worksheet to help you master commas in introductory clauses and score full marks: 

1. Look for introductory words – If a sentence starts with words like “when,” “if,” “because,” “although,” “while,” “before,” “after,” “as,” “since,” “until,” or “whereas,” there is probably an introductory clause. Put a comma after that clause. 

2. The comma comes after the clause, not after the word – “When I arrived, she left.” The comma is after “arrived” (the whole clause), not just after “When.” 

3. Short introductory clauses still need a comma – Even if the introductory clause is short, use a comma. “After lunch, we went to the park.” (comma needed) “If it rains, we will stay home.” (comma needed) 

4. Introductory clauses come at the beginning – A comma is used after an introductory clause at the beginning of a sentence. If the clause is at the end, no comma is needed. “We stayed home because it was raining.” (no comma before “because” – this is not an introductory clause at the beginning). 

5. Common introductory clause starters to memorize – When, If, Because, Although, While, Before, After, As, Since, Until, Wherever, Whenever, Wherever. 

6. What examiners expect – Examiners expect you to add a comma after an introductory clause at the beginning of a sentence. They expect you to know that “When I arrived she left” is missing a comma. They expect you to correct errors like “After school we went home” to “After school, we went home.” 

7. How to score full marks – When answering multiple-choice questions, look for the comma after the first few words of the sentence. If the sentence starts with an introductory word and has no comma, it is incorrect. If it has a comma in the right place, it is correct. 

8. For sentence rewriting (Exercise No. 4) – Read each sentence. Does it start with an introductory word (when, if, because, although, while, before, after)? If yes, the first part of the sentence is the introductory clause. Put a comma right after that clause, before the main clause. 

9. For paragraph correction (Exercise No. 5) – Read the paragraph slowly. Look for every sentence that starts with “When,” “After,” “Although,” “Because,” “While,” or “Before.” These are introductory clauses. Add a comma after the clause. For example, “When I reached the playground” → add comma → “When I reached the playground, I saw my friends...” 

10. Remember: not every “when” or “if” needs a comma** – If the word is not starting an introductory clause, you might not need a comma. But in this worksheet, all the examples are introductory clauses at the beginning of sentences, so they all need commas.
