The worksheet contains two questions, and I’ll solve each below:

Problem 2

"Sam recogió 15 cubetas de agua de lluvia. Usó 8 cubetas para regar sus plantas. ¿Cuántas cubetas de agua de lluvia le quedan a Sam?"

Solution:

• Sam started with 15 buckets of rainwater.
• He used 8 buckets.
• To find the remaining buckets: $15 - 8 = 7$.

Answer: Sam le quedan 7 cubetas de agua de lluvia.

Problem 3

"Había 19 tortugas nadando en el estanque. Algunas tortugas subieron a las rocas secas y ahora sólo hay 8 tortugas nadando. ¿Cuántas tortugas hay en las rocas secas?"

Solution:

• There were initially 19 turtles swimming.
• Now, only 8 turtles remain swimming.
• To find the number of turtles on the dry rocks: $19 - 8 = 11$.

Answer: Hay 11 tortugas en las rocas secas.

Would you like further details on these solutions or have any questions?

Here are 5 related questions to practice:

1. If Sam used 3 more buckets, how many would he have left?
2. If 5 more turtles joined the pond, how many would be swimming?
3. If Sam started with 20 buckets instead of 15, how many would he have left after using 8?
4. How many turtles would be on the rocks if only 5 were left swimming?
5. If Sam finds 10 more buckets, how many would he have in total after using 8?

Tip: When solving subtraction problems, carefully identify what each number represents to ensure clarity.
