Which of the following is a desirable practice in the context of teaching and learning of measurement of volume?

Options

A. Begin by writing the formula of volume of a cube.
B. Encourage precise calculation right from the beginning.
C. Begin by introducing students to the volume of 2-D figures.
D. Encourage students to figure out ways to calculate the volume of different objects.

Answer

To determine the desirable practice in the context of teaching and learning the measurement of volume, we can analyze the provided options step by step:

1. **Understanding the Concept of Volume**: Before diving into the options, it's essential to understand what volume is. Volume refers to the amount of space that a substance (solid, liquid, gas, or plasma) occupies or that is enclosed within a container.

2. **Analyzing the Options**:
- **Option A**: "Begin by writing the formula of volume of a cube."
- This approach is not effective because it promotes rote learning rather than understanding.
- **Option B**: "Encourage precise calculation right from the beginning."
- This is also not advisable, as making errors is a natural part of the learning process, especially in mathematics.
- **Option C**: "Begin by introducing students to the volume of 2D figures."
- While this could be a starting point, it does not directly address the measurement of volume, which is inherently a 3D concept.
- **Option D**: "Encourage students to figure out ways to calculate the volume of different objects."
- This option promotes exploration and understanding, allowing students to engage with the concept of volume in a practical manner.

3. **Conclusion**: After analyzing all the options, it is clear that **Option D** is the most desirable practice. It encourages students to actively engage with the concept of volume by exploring different methods to calculate it, fostering a deeper understanding of the subject.
