Problem Overview:
The task involves writing repeated addition sentences and multiplication sentences for each given model. The models represent groups of objects, and the goal is to express the total number of objects using both repeated addition and multiplication.
Solution:
####
Model 1: Balloons
-
Image Description: There are 3 groups of balloons, with 2 balloons in each group.
-
Repeated Addition:
- Each group has 2 balloons.
- Total: \( 2 + 2 + 2 = 6 \)
-
Multiplication:
- Number of groups: 3
- Number of balloons per group: 2
- Total: \( 3 \times 2 = 6 \)
Answer:
- Repeated Addition: \( 2 + 2 + 2 = 6 \)
- Multiplication: \( 3 \times 2 = 6 \)

####
Model 2: Taxis
-
Image Description: There are 2 groups of taxis, with 5 taxis in each group.
-
Repeated Addition:
- Each group has 5 taxis.
- Total: \( 5 + 5 = 10 \)
-
Multiplication:
- Number of groups: 2
- Number of taxis per group: 5
- Total: \( 2 \times 5 = 10 \)
Answer:
- Repeated Addition: \( 5 + 5 = 10 \)
- Multiplication: \( 2 \times 5 = 10 \)

####
Model 3: Motorcycles
-
Image Description: There are 4 groups of motorcycles, with 1 motorcycle in each group.
-
Repeated Addition:
- Each group has 1 motorcycle.
- Total: \( 1 + 1 + 1 + 1 = 4 \)
-
Multiplication:
- Number of groups: 4
- Number of motorcycles per group: 1
- Total: \( 4 \times 1 = 4 \)
Answer:
- Repeated Addition: \( 1 + 1 + 1 + 1 = 4 \)
- Multiplication: \( 4 \times 1 = 4 \)

####
Model 4: Bicycles
-
Image Description: There are 2 groups of bicycles, with 5 bicycles in each group.
-
Repeated Addition:
- Each group has 5 bicycles.
- Total: \( 5 + 5 = 10 \)
-
Multiplication:
- Number of groups: 2
- Number of bicycles per group: 5
- Total: \( 2 \times 5 = 10 \)
Answer:
- Repeated Addition: \( 5 + 5 = 10 \)
- Multiplication: \( 2 \times 5 = 10 \)

####
Model 5: Toy Cars
-
Image Description: There are 4 groups of toy cars, with 4 toy cars in each group.
-
Repeated Addition:
- Each group has 4 toy cars.
- Total: \( 4 + 4 + 4 + 4 = 16 \)
-
Multiplication:
- Number of groups: 4
- Number of toy cars per group: 4
- Total: \( 4 \times 4 = 16 \)
Answer:
- Repeated Addition: \( 4 + 4 + 4 + 4 = 16 \)
- Multiplication: \( 4 \times 4 = 16 \)
---

Boxed Final Answer:
\[
\boxed{
\begin{aligned}
1. & \quad 2 + 2 + 2 = 6, \quad 3 \times 2 = 6 \\
2. & \quad 5 + 5 = 10, \quad 2 \times 5 = 10 \\
3. & \quad 1 + 1 + 1 + 1 = 4, \quad 4 \times 1 = 4 \\
4. & \quad 5 + 5 = 10, \quad 2 \times 5 = 10 \\
5. & \quad 4 + 4 + 4 + 4 = 16, \quad 4 \times 4 = 16
