Original Paragraph:

He then insisted that we go for a walk together before I went to school. Afterschool, he me met outside on the sidewalk with a ball in his mouth, he wouldn’t go home with me until we played fetch I tried to do my homework, but he ate it! We had a bowl of cereal for dinner! Then he made me sleep on couch while he slept in my bed! I wonder if he’ll still be in charge tomorrow...

Now, let’s go through the paragraph sentence by sentence and apply corrections based on the key.

---

Step-by-step Editing:

1. "One day when I woke up, my parents were missing."
- This sentence is grammatically correct.
- But "my parents were missing" might be better followed by a comma or period — but it's okay as is.
- ✔ No change needed.

2. "Instead, my dog was charge!"
- “charge” is incorrect → should be “in charge”
- So, "charge" → "in charge"
- Also, the exclamation mark is fine, but the sentence needs the word "in" inserted.
- Use symbol A (insert word) → insert "in" before "charge"
- Use X (spelling mistake) on "charge" → actually, it's not just a spelling error; it's a missing word.
- But since "charge" is spelled correctly, it's a missing word, so use A to add "in".
- Final: "Instead, my dog was in charge!"
- ✔ Correction: Add "in" using A.

3. "When I went into the kitchen to eat breakfast, I found him at the stove making me hot canned dog food."
- Grammatically okay.
- But “hot canned dog food” sounds odd — maybe “canned hot dog food”? But likely meant as “hot canned dog food” — acceptable.
- No major errors.
- ✔ No change needed.

4. "He then insisted that we go for a walk together before I went to school."
- Correct.
- ✔ No change needed.

5. "Afterschool, he me met outside on the sidewalk with a ball in his mouth, he wouldn’t go home with me until we played fetch"
- Problems:
- "Afterschool" → should be "After school" (two words)
- Use X for spelling mistake (but actually, it's a spacing issue; "afterschool" is a misspelled compound)
- So, X → correct to "After school"
- "he me met" → word order is wrong → should be "he met me"
- Use ~ (change order of words) → swap "me" and "met"
- Comma splice: two independent clauses joined by a comma
- "he met me..." and "he wouldn't go home..." → need a conjunction or period
- Use O O O to add punctuation — add "and" or a semicolon/period
- Best: add "and" after the comma → "he met me... and he wouldn’t..."
- "fetch" → should be "fetch!" (exclamation) or just end the sentence
- But it's cut off — seems like a run-on
- Actually, next sentence starts with "I tried..."
- So, fix the run-on: separate the sentences

Let's restructure:

> After school, he met me outside on the sidewalk with a ball in his mouth, and he wouldn’t go home with me until we played fetch.

- Corrections:
- X on "Afterschool" → change to "After school"
- ~ on "he me met" → change to "he met me"
- A to add "and" after the comma
- O O O to add comma or period — here, adding "and" fixes the comma splice
- Possibly O O O to add period after "fetch" if splitting

But wait — the next part is:
> "I tried to do my homework, but he ate it!"

So, we need to split the long sentence.

Better version:

> After school, he met me outside on the sidewalk with a ball in his mouth. He wouldn’t go home with me until we played fetch.

So:
- Add O O O to add period after "mouth"
- Then start new sentence: "He wouldn’t go home..."

But the original has no space between "fetch" and "I tried", so we must fix the run-on.

Final correction:
- X: "Afterschool" → "After school"
- ~: "he me met" → "he met me"
- O O O: add period after "mouth"
- O O O: add comma or period after "fetch" → but now it's a new sentence
- Actually, the next sentence begins with "I tried", so we can keep it as:
- "After school, he met me outside on the sidewalk with a ball in his mouth. He wouldn’t go home with me until we played fetch."

So:
- X on "Afterschool"
- ~ on "he me met"
- O O O to add period after "mouth"
- O O O to add period after "fetch"? No — next sentence starts with "I tried"

Wait — the original says:
> "Afterschool, he me met outside on the sidewalk with a ball in his mouth, he wouldn’t go home with me until we played fetch I tried to do my homework..."

That’s a run-on — no punctuation between "fetch" and "I tried".

So:
- Add O O O to add period after "fetch"
- Or add comma + and?

But best: break into two sentences.

So:
- O O O to add period after "fetch"
- Then start new sentence: "I tried..."

But the original has no space — so we must fix the run-on.

Therefore:
- Add O O O → add period after "fetch"
- Then E to capitalize "I" in "I tried"

6. "I tried to do my homework, but he ate it!"
- Correct.
- ✔ No change needed.

7. "We had a bowl of cereal for dinner!"
- Correct.
- ✔ No change needed.

8. "Then he made me sleep on couch while he slept in my bed!"
- Missing article: "on couch" → should be "on the couch"
- Use A to add "the"
- Also, the exclamation is fine.
- ✔ Add "the" using A

9. "I wonder if he’ll still be in charge tomorrow..."
- The ellipsis is okay, but could be a period.
- However, it's used for thought trailing off — acceptable.
- ✔ No change needed.

Final Edited Paragraph:

> One day when I woke up, my parents were missing. Instead, my dog was in charge! When I went into the kitchen to eat breakfast, I found him at the stove making me hot canned dog food. He then insisted that we go for a walk together before I went to school. After school, he met me outside on the sidewalk with a ball in his mouth. He wouldn’t go home with me until we played fetch. I tried to do my homework, but he ate it! We had a bowl of cereal for dinner! Then he made me sleep on the couch while he slept in my bed! I wonder if he’ll still be in charge tomorrow...

Summary of Edits:

| Original Text | Correction | Symbol Used |
|---------------|------------|-------------|
| "charge" | → "in charge" | A (add "in") |
| "Afterschool" | → "After school" | X (spelling/word form) |
| "he me met" | → "he met me" | ~ (change word order) |
| Comma splice after "mouth" | → add period | O O O (add punctuation) |
| Run-on after "fetch" | → add period | O O O |
| "on couch" | → "on the couch" | A (add "the") |
| "I tried" | → capitalize "I" | E (capitalize) |

Wait — did we miss E? Yes, the first word "I" in "I tried" is lowercase — should be capitalized.

So:
- E on "I" in "I tried"

Also, the paragraph should be indented — use H to indent the paragraph.

But the worksheet says: "Indent paragraph" — so we should use H at the beginning.

Final Answer with Symbols Applied:

Let’s write the corrected version with symbols marked where needed.

> H
> One day when I woke up, my parents were missing. Instead, my dog was A(in) charge! When I went into the kitchen to eat breakfast, I found him at the stove making me hot canned dog food. He then insisted that we go for a walk together before I went to school. X(Afterschool), ~(he me met) outside on the sidewalk with a ball in his mouth, O O O( . ) O O O( . ) E(I) tried to do my homework, but he ate it! We had a bowl of cereal for dinner! Then he made me sleep on A(the) couch while he slept in my bed! I wonder if he’ll still be in charge tomorrow...

Wait — better to show the corrected text and list the edits.
