Step-by-Step Solution:

#### 1. Read the Passage Carefully:
The passage states:
> "My dog is named Lucky. Lucky can do lots of tricks. She knows how to sit and lie down when I tell her to. Lucky also can roll over! Another thing Lucky can do is to shake her paw to say hello to people. Lucky is the best dog in the world."

#### 2. Identify the Main Idea:
The main idea is the central point or overall message of the passage. It should be broad enough to encompass all the details but specific enough to reflect the core topic.

From the passage, the main idea is:
> "Lucky is the best dog in the world."

This sentence summarizes the overall theme of the passage, which is praising Lucky for her abilities and qualities.

#### 3. Identify Supporting Details:
Supporting details are specific pieces of information that provide evidence or examples to support the main idea. In this case, the supporting details describe the tricks Lucky can perform.

The supporting details from the passage are:
1. "Lucky can do lots of tricks."
2. "She can sit and lie down."
3. "Lucky can roll over!"
4. "She can shake paws."

These sentences provide specific examples of Lucky's abilities, which support the claim that she is the best dog in the world.

#### 4. Organize the Sentences:
Now, we need to organize the sentences into the appropriate categories:
- Main Idea: "Lucky is the best dog in the world."
- Supporting Details:
- Supporting Detail #1: "Lucky can do lots of tricks."
- Supporting Detail #2: "She can sit and lie down."
- Supporting Detail #3: "Lucky can roll over!"
- Supporting Detail #4: "She can shake paws."

Since there are only three boxes for supporting details in the worksheet, we can choose any three of these sentences to fill in the boxes. For example:
- Supporting Detail #1: "Lucky can do lots of tricks."
- Supporting Detail #2: "She can sit and lie down."
- Supporting Detail #3: "Lucky can roll over!"

#### 5. Final Answer:
- Main Idea: "Lucky is the best dog in the world."
- Supporting Details:
- Supporting Detail #1: "Lucky can do lots of tricks."
- Supporting Detail #2: "She can sit and lie down."
- Supporting Detail #3: "Lucky can roll over!"
