What sequence of the following instructions should be followed in development of a mathematical concept in elemental classes ?
I. Drawing pictures
II. Using symbolic representation
III. Providing experiences
IV. Explaining through language

Options

A. III,I,II,IV
B. IV,III,I,II
C. III,IV,I,II
D. IV,III,II,I

Explanation

To develop a mathematical concept in elementary classes, the following sequence of instructions should be followed:

1. **Providing Experiences (III)**: Begin by giving students hands-on experiences related to the mathematical concept. This could involve using physical objects, engaging in activities, or exploring real-life situations that relate to the concept. This step is crucial as it lays the foundation for understanding by connecting the concept to tangible experiences.

2. **Drawing Pictures (I)**: After providing experiences, the next step is to encourage students to draw pictures. Visual representation helps students to conceptualize and internalize the mathematical ideas. For example, if the concept is about shapes, students can draw different shapes to understand their properties better.

3. **Using Symbolic Representation (II)**: Once students have a grasp of the concept through experiences and visual aids, introduce symbolic representation. This involves using numbers, symbols, and equations to represent the concepts they have learned. This step helps bridge the gap between concrete understanding and abstract thinking.

4. **Explaining Through Language (IV)**: Finally, encourage students to explain their understanding through language. This could involve discussing their drawings, explaining their thought processes, or articulating the mathematical concepts in their own words. This step reinforces their understanding and allows them to communicate their knowledge effectively.

Thus, the correct sequence is: **III (Providing Experiences), I (Drawing Pictures), II (Using Symbolic Representation), IV (Explaining Through Language)**.
