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 proofreading and editing 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) and identify the differences and errors.

🔍 Step 1: Compare the Two Versions

Here are the two paragraphs:

#### ✔ Top Version (Original Text):
> 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.

#### ✘ Bottom Version (Edited Version):
> 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.

Wait — both texts appear identical. That suggests the task might be to edit the original version (the top one), since the bottom one is just a duplicate.

So let’s focus on editing the original paragraph for grammar, spelling, punctuation, and word usage errors.

🛠️ Step 2: Identify Errors in the Paragraph

Let’s go through the paragraph sentence by sentence:

---

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

- Error: Missing comma after "tank"
- Error: "excitin" → misspelled; should be "exciting"
- Fix: "I have a really cool fish tank, lots of exciting things inside."

> Note: This is a run-on sentence. Better phrasing would be:
> "I have a really cool fish tank with lots of exciting things inside."

But for this exercise, we’re likely focusing on correcting errors, not full rewriting.

---

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

- Error: "Their" → incorrect word. Should be "There" ("There is")
- Error: "is" should be "are" because "guppies, tetras, and a tiny shark" is plural
- Fix: "There are guppies, tetras, and a tiny shark inside."

---

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

- Error: "snail" → should be "snails" (plural)
- Fix: "Also, there are three snails that climb up the glass walls."

---

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

- Error: "eate" → misspelled; should be "eat"
- Fix: "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."

- Error: "live" → subject is singular ("frog"), so should be "lives"
- Error: "hide" → should be "hides" (third person singular)
- Fix: "A frog named Flipper also lives in the tank, but he usually hides under the rocks."

> Bonus: "flipper" should be capitalized if 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, 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.
