Growing Pattern with Shapes | Turtle Diary Worksheet - Free Printable

Problem Analysis:

The task involves completing patterns by identifying the missing shapes in each sequence. Let's analyze each part step by step.

---

#### Part 1:
The given pattern is:
```
1. □ (green) ○ (orange) ○ (orange)
□ (green) ○ (orange) ○ (orange)
□ (green) ○ (orange) ○ (orange) □ (green) ○ (orange) ○ (orange)
```

- Observation:
- The pattern alternates between a green square (`□`) and two orange circles (`○`).
- Each row repeats this sequence.

- Missing Shapes:
- The third row already shows the complete sequence: `□ ○ ○ □ ○ ○`.
- No additional shapes are needed here.

#### Part 2:
The given pattern is:
```
2. △ (blue) △ (pink) □ (yellow)
△ (blue) △ (pink) □ (yellow)
△ (blue) △ (pink) □ (yellow) △ (blue) △ (pink) □ (yellow)
```

- Observation:
- The pattern alternates between a blue triangle (`△`), a pink triangle (`△`), and a yellow square (`□`).
- Each row repeats this sequence.

- Missing Shapes:
- The third row already shows the complete sequence: `△ △ □ △ △ □`.
- No additional shapes are needed here.

---

#### Part 3:
The given pattern is:
```
3. ▲ (red)
▲ (red)
▲ (red) ▲ (red)
▲ (red) ▲ (red) ▲ (red)
```

- Observation:
- The pattern starts with a single red triangle (`▲`).
- In the second row, there is still one red triangle.
- In the third row, there are two red triangles.
- In the fourth row, there are three red triangles.
- The number of red triangles increases by one in each subsequent row.

- Missing Shapes:
- The fifth row should have four red triangles to follow the pattern.
- Therefore, the missing shapes are: `▲ ▲ ▲ ▲`.

Final Answer:

1. No additional shapes needed.
2. No additional shapes needed.
3. The missing shapes are: `▲ ▲ ▲ ▲`.

Boxed Answer:
\[
\boxed{▲ ▲ ▲ ▲}
\]
