Let’s solve each problem step by step, based on the visual models shown in the image. The goal is to write a
repeated addition sentence and a
multiplication sentence for each model.

Problem 1: Donuts
- There are
2 groups (ovals), each with
4 donuts.
- Repeated Addition: Add the number of donuts in each group → 4 + 4 = 8
- Multiplication: Number of groups × items per group → 2 × 4 = 8
✔ Answer:
- Repeated Addition:
4 + 4 = 8
- Multiplication:
2 × 4 = 8
---
Problem 2: Stars
- There are
3 groups, each with
3 stars.
- Repeated Addition: 3 + 3 + 3 = 9
- Multiplication: 3 × 3 = 9
✔ Answer:
- Repeated Addition:
3 + 3 + 3 = 9
- Multiplication:
3 × 3 = 9
---
Problem 3: Apples
- There are
4 groups, each with
2 apples.
- Repeated Addition: 2 + 2 + 2 + 2 = 8
- Multiplication: 4 × 2 = 8
✔ Answer:
- Repeated Addition:
2 + 2 + 2 + 2 = 8
- Multiplication:
4 × 2 = 8
---
Problem 4: Beach Balls
- There are
2 groups, each with
5 beach balls.
- Repeated Addition: 5 + 5 = 10
- Multiplication: 2 × 5 = 10
✔ Answer:
- Repeated Addition:
5 + 5 = 10
- Multiplication:
2 × 5 = 10
---
Problem 5: Diamonds
- There are
4 groups, each with
3 diamonds.
- Repeated Addition: 3 + 3 + 3 + 3 = 12
- Multiplication: 4 × 3 = 12
✔ Answer:
- Repeated Addition:
3 + 3 + 3 + 3 = 12
- Multiplication:
4 × 3 = 12

✔ Final Answers Summary:
| Problem | Repeated Addition | Multiplication |
|---------|----------------------------|----------------|
| 1 | 4 + 4 = 8 | 2 × 4 = 8 |
| 2 | 3 + 3 + 3 = 9 | 3 × 3 = 9 |
| 3 | 2 + 2 + 2 + 2 = 8 | 4 × 2 = 8 |
| 4 | 5 + 5 = 10 | 2 × 5 = 10 |
| 5 | 3 + 3 + 3 + 3 = 12 | 4 × 3 = 12 |

## 💡 Key Concept:
Multiplication is repeated addition.
If you have *n* groups of *m* items, then:
>
Repeated Addition: m + m + ... + m (n times)
>
Multiplication: n × m
This helps build understanding of multiplication as a shortcut for adding equal groups.
