Problem 1: Apples
Image: There are 4 circles, each containing 4 apples.
- Number of groups = 4
- Apples in each group = 4
So:
> ___ groups of ___ apples each.
> = ___ + ___ + ___ + ___
> = ___ × ___
> = ___
Step-by-step:
- 4 groups of 4 apples each.
- Add them: 4 + 4 + 4 + 4 = 16
- Multiplication: 4 × 4 = 16
✔ Answer:
> 4 groups of 4 apples each.
> = 4 + 4 + 4 + 4
> = 4 × 4
> = 16

Problem 2: Marbles
Image: There are 5 circles, each with 3 marbles.
- Number of groups = 5
- Marbles in each group = 3
> ___ groups of ___ marbles each.
> = ___ + ___ + ___ + ___ + ___
> = ___ × ___
> = ___
Step-by-step:
- 5 groups of 3 marbles each.
- Add them: 3 + 3 + 3 + 3 + 3 = 15
- Multiplication: 5 × 3 = 15
✔ Answer:
> 5 groups of 3 marbles each.
> = 3 + 3 + 3 + 3 + 3
> = 5 × 3
> = 15

Problem 3: Boats
Image: There are 3 ovals (groups), each containing 5 boats.
- Number of groups = 3
- Boats in each group = 5
> ___ groups of ___ boats each.
> = ___ + ___ + ___
> = ___ × ___
> = ___
Step-by-step:
- 3 groups of 5 boats each.
- Add them: 5 + 5 + 5 = 15
- Multiplication: 3 × 5 = 15
✔ Answer:
> 3 groups of 5 boats each.
> = 5 + 5 + 5
> = 3 × 5
> = 15

✔ Final Answers:
1.
4 groups of 4 apples each.
= 4 + 4 + 4 + 4
= 4 × 4
= 16
2.
5 groups of 3 marbles each.
= 3 + 3 + 3 + 3 + 3
= 5 × 3
= 15
3.
3 groups of 5 boats each.
= 5 + 5 + 5
= 3 × 5
= 15
