Choose the correct option :

Question

Accepted Answer

Option 4, which includes statements (a) and (b), is the correct answer for understanding the computation in basic operations for Grade-II learners. Here's why:

1. **Explanation for Option 4 (Correct Answer):**

- **Statement (a): It involves child's ability to develop informal strategies.**
     - At the Grade-II level, children are encouraged to develop informal strategies for solving basic arithmetic problems. This involves using intuitive methods and personal logic to understand and solve problems, which is crucial for building a strong mathematical foundation. Informal strategies might include using fingers, drawing pictures, or breaking numbers into smaller parts to make calculations easier.

- **Statement (b): It involves child's ability to estimate.**
     - Estimation is a key skill for Grade-II learners as it helps them make reasonable guesses about the results of arithmetic operations. This skill is important for developing number sense and understanding the relative size of numbers. Estimation allows children to check the reasonableness of their answers and to make quick calculations in everyday situations.

2. **Explanation for why other options are incorrect:**

- **Option 1: Only (c)**
     - Statement (c) involves the child's ability to do calculations with large numbers. This is not typically expected of Grade-II learners, as their focus is on understanding basic operations with smaller numbers. Large number calculations are generally introduced at a higher grade level.

- **Option 2: (b) and (c)**
     - While statement (b) is correct, statement (c) is not applicable to Grade-II learners for the reasons mentioned above. Therefore, this option is incorrect because it includes an inappropriate expectation for this grade level.

- **Option 3: (a) and (c)**
     - Similar to Option 2, while statement (a) is correct, statement (c) is not suitable for Grade-II learners. This makes Option 3 incorrect as it pairs a correct statement with an incorrect one.

In conclusion, Option 4 is the correct choice because it accurately reflects the skills that Grade-II learners are expected to develop in terms of computation in basic operations. These skills include developing informal strategies and the ability to estimate, both of which are foundational for their mathematical growth.
