Proofreading Paragraphs - Printable Worksheets - Free Printable

It looks like you've uploaded a worksheet titled "Fish Tank" from Super Teacher Worksheets, which is focused on editing and proofreading skills. The task asks students to find as many mistakes as they can in the paragraph about a fish tank.

Let's analyze both versions of the text (top and bottom) — although they appear identical at first glance — and identify any grammar, punctuation, spelling, or capitalization errors.

🔍 Original Text (from the worksheet):

> I have a really cool fish tank lots of excitin things inside. Their is guppies, tetras, and a tiny shark inside. Also, there are three snail that climb up the glass walls. They eate the green algae and keep the tank clean. A frog named flipper also live in the tank, but he usually hide under the rocks. It’s fun to watch all the different creatures in my tank.

✔ Step-by-Step Mistake Identification:

Let’s go sentence by sentence and correct each error.

---

#### 1. "I have a really cool fish tank lots of excitin things inside."

- ✘ "lots of excitin things" → Incorrect word form and spelling.
- "excitin" should be "exciting" (spelling).
- Missing comma after "tank" to separate two independent clauses.
- Needs a conjunction or rephrasing.

✔ Corrected:
"I have a really cool fish tank. There are lots of exciting things inside."

OR better:
"I have a really cool fish tank with lots of exciting things inside."

---

#### 2. "Their is guppies, tetras, and a tiny shark inside."

- ✘ "Their is" → Wrong word. "Their" is possessive; it should be "There is".
- ✘ "guppies, tetras, and a tiny shark" → Correct list, but the subject is plural ("guppies, tetras, shark"), so verb should be "are", not "is".

✔ Corrected:
"There are guppies, tetras, and a tiny shark inside."

---

#### 3. "Also, there are three snail that climb up the glass walls."

- ✘ "snail" → Should be plural: "snails" (three snails).
- ✘ "that climb" → Should be "who climb" or "that climb" is acceptable for animals, but "who" is more personable.
- However, "that" is grammatically okay here.

✔ Corrected:
"Also, there are three snails that climb up the glass walls."

---

#### 4. "They eate the green algae and keep the tank clean."

- ✘ "eate" → Spelling error. Should be "eat".

✔ Corrected:
"They eat the green algae and keep the tank clean."

---

#### 5. "A frog named flipper also live in the tank, but he usually hide under the rocks."

- ✘ "live" → Subject is singular ("frog"), so verb should be "lives".
- ✘ "hide" → Should be "hides" (present tense, singular subject).

✔ Corrected:
"A frog named Flipper also lives in the tank, but he usually hides under the rocks."

Note: "Flipper" should be capitalized since it's a name.

---

#### 6. "It’s fun to watch all the different creatures in my tank."

- ✔ This sentence is correct.

---

🛠 Final Corrected Version:

> I have a really cool fish tank with lots of exciting things inside. There are guppies, tetras, and a tiny shark inside. Also, there are three snails that climb up the glass walls. They eat the green algae and keep the tank clean. A frog named Flipper also lives in the tank, but he usually hides under the rocks. It’s fun to watch all the different creatures in my tank.

✔ List of Mistakes Found (Total: 8):

| Error | Type | Correction |
|------|------|------------|
| 1. "excitin" | Spelling | → "exciting" |
| 2. Missing comma or conjunction | Punctuation/Run-on | Add "with" or split into two sentences |
| 3. "Their is" | Homophone | → "There is" |
| 4. "is" → "are" | Subject-verb agreement | → "are" (plural subjects) |
| 5. "snail" | Pluralization | → "snails" |
| 6. "eate" | Spelling | → "eat" |
| 7. "live" | Verb agreement | → "lives" |
| 8. "hide" | Verb agreement | → "hides" |
| 9. "flipper" | Capitalization | → "Flipper" |

Wait — we now have 9 mistakes.

But note: some people might count the run-on sentence as one mistake, and others may combine the two verb errors in the last sentence.

However, most common mistakes are:

1. excitin → exciting
2. Their is → There are
3. snail → snails
4. eate → eat
5. live → lives
6. hide → hides
7. flipper → Flipper
8. Missing "with" or run-on sentence

So, 8–9 mistakes depending on how you count.

✔ Answer:

You can find 8 to 9 mistakes in the paragraph.

✔ Summary of Corrections:

- Fix spelling: excitin → exciting, eate → eat
- Fix homophone: Their → There
- Fix subject-verb agreement: is → are, live → lives, hide → hides
- Fix plural: snail → snails
