Possible indicator pertaining to visual memory barrier hampering with learner's mathematical performance is

Options

A. difficulty in retaining mathematical facts and difficulty in telling time
B. difficulty in using a number line
C. difficulty to count on within a sequence
D. difficulty in handling small manipulations

Answer

To solve the question regarding the possible indicator pertaining to a visual memory barrier that hampers a learner's mathematical performance, we will analyze the options provided and determine which one aligns with the concept of visual memory barriers.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an indicator related to visual memory barriers that affect mathematical performance. Visual memory barriers refer to difficulties in remembering visual information.

2. **Analyze the Options**:
- **Option A**: Difficulty in retaining mathematical facts and difficulty in telling time.
- **Option B**: Difficulty in using a number line.
- **Option C**: Difficulty to count on with a sequence.
- **Option D**: Difficulty in handling small manipulations.

3. **Evaluate Each Option**:
- **Option A**: This option mentions both retaining mathematical facts and telling time, which involves visual memory (e.g., reading clocks, remembering formulas).
- **Option B**: Difficulty in using a number line is more about understanding numerical relationships rather than visual memory.
- **Option C**: Counting in a sequence is a skill related to numerical understanding rather than visual memory.
- **Option D**: Handling small manipulations does not directly relate to visual memory barriers.

4. **Select the Correct Option**: Based on the analysis, **Option A** is the most relevant as it directly relates to visual memory barriers impacting the retention of mathematical facts and the ability to tell time.

5. **Conclusion**: The correct answer is **Option A: Difficulty in retaining mathematical facts and difficulty in telling time**.
