Step-by-step solution for: English Worksheets | 8th Grade Common Core Worksheets
Here's the corrected version of each sentence with proper commas and punctuation added, followed by an explanation for each.
---
1. John likes to do many things after school. First, he gets home and does all his homework. Then, he eats dinner with his parents.
✔ Explanation:
- Added a period after “school” to end the first complete thought.
- Added a comma after “First” because it’s an introductory adverb starting a new sentence.
- Added a comma after “Then” for the same reason — it’s an introductory adverb.
- Fixed typo: “and d” → “and”.
---
2. After dinner with his parents, John likes to play video games. He usually sits on his couch, pillow, or chair.
✔ Explanation:
- Added a comma after the introductory phrase “After dinner with his parents” to separate it from the main clause.
- Removed “with” before “video games” — we say “play video games,” not “play with video games” (unless referring to playing *with* someone *on* games, which isn’t the case here).
- Added commas around “pillow” in the list “couch, pillow, or chair” — this is the Oxford comma rule (optional in some styles, but recommended for clarity). The items are separate options, so commas help avoid confusion.
---
3. After playing video games, John brushes his teeth, tells his mom he’s going to sleep, and walks to his room.
✔ Explanation:
- Added comma after introductory phrase “After playing video games.”
- Added commas to separate the three actions in the compound predicate: “brushes his teeth, tells his mom..., and walks...” — this is the serial (Oxford) comma usage, which clarifies that these are three distinct actions.
- Also fixed “he’s” (correct contraction of “he is”) — already correct.
---
4. When John awakes, he knows that he must first brush his teeth, comb his hair, and pack his lunch.
✔ Explanation:
- Added comma after the introductory clause “When John awakes.”
- Added commas between the three items in the list: “brush his teeth, comb his hair, and pack his lunch.” Again, using the Oxford comma for clarity and standard punctuation practice.
---
5. As John arrives at school, he is greeted by his friends Joey, Sam, and Freddy.
✔ Explanation:
- Added comma after the introductory clause “As John arrives at school.”
- Changed “to school” to “at school” — “arrives at” is the correct preposition for locations like schools, airports, etc.
- Added commas between the names in the list: “Joey, Sam, and Freddy.” This follows standard list punctuation with the Oxford comma.
---
✔ Final Answer (All Corrected Sentences):
1. John likes to do many things after school. First, he gets home and does all his homework. Then, he eats dinner with his parents.
2. After dinner with his parents, John likes to play video games. He usually sits on his couch, pillow, or chair.
3. After playing video games, John brushes his teeth, tells his mom he’s going to sleep, and walks to his room.
4. When John awakes, he knows that he must first brush his teeth, comb his hair, and pack his lunch.
5. As John arrives at school, he is greeted by his friends Joey, Sam, and Freddy.

📘 Teaching Tip:
This worksheet focuses on:
- Using commas after introductory elements (phrases/clauses).
- Using commas in lists (serial/Oxford comma).
- Proper sentence structure and capitalization.
- Fixing minor grammar/word choice issues (like “play with video games” → “play video games”).
These are key skills aligned with CCSS.ELA-Literacy.L.8.2a, which states students should “Use punctuation (commas, parentheses, dashes) to set off nonrestrictive/parenthetical elements.”
