The correct Answer is:
To determine the developmental phase of numbers that Shailja is in, we need to analyze her ability to express the number 4 in different ways, such as `4 = 2 + 2` and `4 = 1 + 3`. ### Step-by-Step Solution: 1. **Understanding the Question**: We need to identify the developmental phase of numbers that Shailja is demonstrating when she expresses a number in different ways. 2. **Identifying the Options**: The options provided are: - Quantifying phase - Partitioning phase - Factoring phase - Operating phase 3. **Analyzing Each Phase**: - **Quantifying Phase**: This phase involves understanding and computing values like percentages and fractions. Since Shailja is simply expressing the number 4 in different ways, this phase does not apply. - **Factoring Phase**: In this phase, a child understands factors of numbers and can express a number as a product of its factors. Shailja is not expressing 4 in terms of its factors (like `2 x 2` or `1 x 4`), so this phase does not apply either. - **Operating Phase**: This phase involves performing operations such as addition, subtraction, multiplication, and division. While Shailja is adding numbers to express 4, she is not performing operations in the sense of manipulating numbers through calculations, so this phase does not apply. - **Partitioning Phase**: This phase is characterized by the ability to divide a number into different parts or sums. Since Shailja can express 4 as `2 + 2` and `1 + 3`, she is effectively partitioning the number into different components. 4. **Conclusion**: Based on the analysis, Shailja is in the **Partitioning Phase** of number development because she is dividing the number 4 into different sums. ### Final Answer: Shailja is in the **Partitioning Phase** of number development.
