Let's solve each model step by step, writing both the
repeated addition sentence and the
multiplication sentence.

1. Apples (2 rows of 4 apples)
-
Repeated Addition:
There are 2 groups of 4 apples:
$ 4 + 4 = 8 $
-
Multiplication:
$ 2 \times 4 = 8 $
✔ Answer:
Repeated Addition: $ 4 + 4 = 8 $
Multiplication: $ 2 \times 4 = 8 $
---
2. Oranges (3 groups of 3 oranges)
-
Repeated Addition:
Each group has 3 oranges, and there are 3 groups:
$ 3 + 3 + 3 = 9 $
-
Multiplication:
$ 3 \times 3 = 9 $
✔ Answer:
Repeated Addition: $ 3 + 3 + 3 = 9 $
Multiplication: $ 3 \times 3 = 9 $
---
3. Strawberries (4 groups of 2 strawberries)
-
Repeated Addition:
Each group has 2 strawberries, and there are 4 groups:
$ 2 + 2 + 2 + 2 = 8 $
-
Multiplication:
$ 4 \times 2 = 8 $
✔ Answer:
Repeated Addition: $ 2 + 2 + 2 + 2 = 8 $
Multiplication: $ 4 \times 2 = 8 $

4. Beach Balls (2 groups of 5 beach balls)
-
Repeated Addition:
Each group has 5 beach balls, and there are 2 groups:
$ 5 + 5 = 10 $
-
Multiplication:
$ 2 \times 5 = 10 $
✔ Answer:
Repeated Addition: $ 5 + 5 = 10 $
Multiplication: $ 2 \times 5 = 10 $
---
5. Watermelons (4 groups of 3 watermelons)
-
Repeated Addition:
Each group has 3 watermelons, and there are 4 groups:
$ 3 + 3 + 3 + 3 = 12 $
-
Multiplication:
$ 4 \times 3 = 12 $
✔ Answer:
Repeated Addition: $ 3 + 3 + 3 + 3 = 12 $
Multiplication: $ 4 \times 3 = 12 $
---
✔ Final Answers:
| Model | Repeated Addition | Multiplication |
|------|-------------------|----------------|
| 1 (Apples) | $ 4 + 4 = 8 $ | $ 2 \times 4 = 8 $ |
| 2 (Oranges) | $ 3 + 3 + 3 = 9 $ | $ 3 \times 3 = 9 $ |
| 3 (Strawberries) | $ 2 + 2 + 2 + 2 = 8 $ | $ 4 \times 2 = 8 $ |
| 4 (Beach Balls) | $ 5 + 5 = 10 $ | $ 2 \times 5 = 10 $ |
| 5 (Watermelons) | $ 3 + 3 + 3 + 3 = 12 $ | $ 4 \times 3 = 12 $ |

🔍 Explanation:
-
Repeated Addition means adding the same number multiple times.
-
Multiplication is a shortcut for repeated addition:
$ \text{number of groups} \times \text{number in each group} = \text{total} $
This helps students understand that multiplication is just faster addition! 🍎🍊🍓🏖️🍉
