Beginner-friendly worksheet designed to help music students practice identifying note names on the treble staff.

The task is to identify and name the musical notes shown on the staff. The notes are written in a specific order, and we need to match them with their corresponding names (C, D, E, F, G). Let's solve this step by step.

Step 1: Understand the Staff

- The staff consists of five horizontal lines.
- Notes placed on these lines or spaces correspond to specific pitches.
- The notes C, D, E, F, and G are typically used in beginner music exercises.

Step 2: Identify the Notes

We will analyze each note in the image and determine its position on the staff:

#### First Line:
The notes are already labeled as C, D, E, F, G. These are the reference points.

#### Second Line:
The notes are all on the second line of the staff. According to the reference notes:
- All notes on the second line are D.

So, the answers for the second line are:
```
D D D D D
```

#### Third Line:
The notes are all on the third line of the staff. According to the reference notes:
- All notes on the third line are E.

So, the answers for the third line are:
```
E E E E E
```

#### Fourth Line:
The notes are all on the fourth line of the staff. According to the reference notes:
- All notes on the fourth line are F.

So, the answers for the fourth line are:
```
F F F F F
```

#### Fifth Line:
The notes are all on the fifth line of the staff. According to the reference notes:
- All notes on the fifth line are G.

So, the answers for the fifth line are:
```
G G G G G
```

Final Answer:

Combining all the answers, we get:

```
Second Line: D D D D D
Third Line: E E E E E
Fourth Line: F F F F F
Fifth Line: G G G G G
```

Thus, the complete solution is:
```
\boxed{D D D D D, E E E E E, F F F F F, G G G G G}
```
