Editing and proofreading worksheet with a paragraph about Martin's new bike, featuring tasks to correct capitalization, punctuation, spelling, and word usage.

Explanation:
We need to edit the paragraph by fixing all the mistakes listed on the left side. Let’s go step by step through the text and apply each rule:

Original text (with errors):
*martin got a bike for his birthday. The bike is new. Its a used bike, but its new to Martin and has barely been ridden. Martin is so excited about his birthday gift that he has been riding around the Neighborhood showing it to everybody. If you haven't seen it yet it's only because he hasn't made it all the way to your house yet!*

Now fix each error type:

1. Capitalize letter – First word of sentence must be capitalized.
- “martin” → “Martin”
- Also, “Neighborhood” is not a proper noun here (just a general area), so it should be lowercase: “neighborhood”.
- “If” starts a new sentence → already capitalized, okay.

2. Add a period – Make sure every sentence ends with a period.
- The last sentence ends with “yet!” — exclamation mark is okay, but the instruction says *add a period*, and the list includes “Add a period” as a required fix. However, in editing tasks like this, if a sentence ends with an exclamation mark or question mark, it’s usually acceptable — but looking at the context, the original uses “yet!” which is fine for excitement. But the instruction says “Add a period” as one of the fixes needed — meaning there is at least one missing period. Let’s check:
Sentences:
1. martin got… → needs period at end of first sentence? Wait — original has:
“martin got a bike for his birthday. The bike is new.” → that’s two sentences, both have periods.
Then: “Its a used bike…” — no period after “new.”? Actually, yes — “The bike is new.” ends with period. So maybe the issue is elsewhere. Let’s read carefully.

Wait — the real issue is punctuation *inside* sentences. Let’s list all corrections systematically.

Better approach: Identify every error in the original paragraph:

- “martin” → should be Martin (capitalize first letter of sentence).
- “Its a used bike” → “Its” should be It’s (contraction of *It is*), and needs apostrophe.
- “but its new to Martin” → “its” should be it’s (again, *it is*), so it’s.
- Missing comma after introductory clause: “If you haven’t seen it yet” → should be followed by a comma before “it’s only because…”
- “Neighborhood” → not a proper noun → neighborhood (lowercase)
- “haven't” is correct (apostrophe in contraction).
- “it's” is correct (apostrophe).
- Check capitalization: “Martin” appears multiple times — all should be capitalized.
- Check commas: After “yet”, before “it’s only because…” → needs comma.
- Also: “The bike is new. Its a used bike…” — this is a run-on logic, but grammatically, it’s two sentences. However, “Its a used bike” is incorrect — should be It’s a used bike.

Let’s rewrite sentence by sentence:

1. *martin got a bike for his birthday.*
→ Martin got a bike for his birthday.

2. *The bike is new.*
→ OK (capitalized, period).

3. *Its a used bike, but its new to Martin*
→ It’s a used bike, but it’s new to Martin
- “Its” → “It’s” (twice)
- Comma after “bike” is already there — good.

4. *and has barely been ridden.*
→ This continues the previous sentence, so we should join with comma or make separate. Original has it as separate sentence? No — in the text it's written as:
“Its a used bike, but its new to Martin and has barely been ridden.”
So it’s one sentence:
“It’s a used bike, but it’s new to Martin and has barely been ridden.”
That’s acceptable (no comma needed before “and” when connecting two verbs with same subject).

5. *Martin is so excited about his birthday gift that he has been riding around the Neighborhood showing it to everybody.*
→ “Neighborhood” → neighborhood (lowercase)
Also: Should there be a comma before “showing”? Not required — “riding around the neighborhood showing it” is fine as is (present participle phrase modifying “riding”).

6. *If you haven't seen it yet it's only because he hasn't made it all the way to your house yet!*
→ Missing comma after “yet”:
If you haven’t seen it yet, it’s only because he hasn’t made it all the way to your house yet!

Also: “haven’t” and “it’s” are correct.

Now check all editing rules from the list:
- ✔ Capitalize letter: Martin → fixed
- ✔ Add a period: All sentences now end properly (last one with ! is acceptable; the task likely considers ! sufficient — and no missing periods remain)
- ✔ Add a quotation mark: None needed — no direct speech.
- ✔ Add a comma: Added comma after “yet”
- ✔ Take words out: None needed — all words are necessary.
- ✔ Spell correctly: Fixed “Its” → “It’s”, “its” → “it’s”, “Neighborhood” → “neighborhood”
- ✔ Indent: Not applicable for this format.
- ✔ Lowercase letter: “neighborhood” corrected
- ✔ Add words: None needed.

Final corrected paragraph:

Martin got a bike for his birthday. The bike is new. It’s a used bike, but it’s new to Martin and has barely been ridden. Martin is so excited about his birthday gift that he has been riding around the neighborhood showing it to everybody. If you haven’t seen it yet, it’s only because he hasn’t made it all the way to your house yet!

Let’s double-check:
- First word “Martin” capitalized ✔
- Periods at ends of sentences ✔
- “It’s” with apostrophe ✔ (twice)
- Comma after “yet” ✔
- “neighborhood” lowercase ✔
- No extra words added or removed unnecessarily ✔
- All spelling correct ✔

Final Answer:
Martin got a bike for his birthday. The bike is new. It’s a used bike, but it’s new to Martin and has barely been ridden. Martin is so excited about his birthday gift that he has been riding around the neighborhood showing it to everybody. If you haven’t seen it yet, it’s only because he hasn’t made it all the way to your house yet!
