Solution to the "Main Idea & Details" Worksheet

---

#### Step 1: Understand the Task
The goal is to identify:
- The main idea of the story (the central point).
- Four supporting details (specific examples that support the main idea).

We are given a short passage about ocean animals and five sentence choices at the bottom. We must place each sentence in the correct box — either as the main idea or one of the details.

---

#### Step 2: Read the Story

> Ocean Animals
> Do you like sharks? Sharks, like many other animals, live in the ocean. Whales and dolphins live in the ocean, too. If you go to the ocean, you may also see crabs, eels, and many kinds of fish. You may even see an octopus! Many animals live in the ocean! Would you like to take a trip to the ocean?

---

#### Step 3: Identify the Main Idea

Look for the most general statement that the entire paragraph supports.

- The last sentence says: "Many animals live in the ocean!"
- This sentence summarizes what all the others are about.
- All the other sentences give examples of animals that live in the ocean.

✔ So, the main idea is: "Many animals live in the ocean."

---

#### Step 4: Identify the Supporting Details

These are specific facts that support the main idea. Let’s look at the sentence choices:

1. You can see crabs in the ocean. → Yes, this is mentioned in the text ("you may also see crabs...") → ✔ Detail
2. Sharks live in the ocean. → Yes, first sentence mentions it → ✔ Detail
3. Whales and dolphins are ocean animals. → Yes, stated directly → ✔ Detail
4. Many fish live in the ocean. → Yes, “many kinds of fish” → ✔ Detail
5. Many animals live in the ocean. → This is the main idea, not a detail → ✘

So, the four details are:
- You can see crabs in the ocean.
- Sharks live in the ocean.
- Whales and dolphins are ocean animals.
- Many fish live in the ocean.

#### Step 5: Fill in the Diagram

```
[detail] [detail]
| |
| |
-------------------------------
| main idea |
| Many animals live in |
| the ocean. |
-------------------------------
| |
| |
[detail] [detail]
```

Now, assign the four details to the four boxes around the main idea.

You can place them in any order since they’re all supporting examples.

✔ Final Answer:

Main Idea (center):
👉 *Many animals live in the ocean.*

Details (surrounding boxes):
1. You can see crabs in the ocean.
2. Sharks live in the ocean.
3. Whales and dolphins are ocean animals.
4. Many fish live in the ocean.

📝 Explanation:

- The main idea is the overall message: that many animals live in the ocean.
- The details are specific examples from the text that prove or support that main idea.
- Each detail gives a different type of ocean animal, showing variety and reinforcing the main idea.

This exercise helps students practice identifying the central idea and how supporting details relate to it — a key reading comprehension skill.
