Mathematical interest refers to an individual's positive and enthusiastic engagement with mathematical concepts, problems, and activities.

Key Points

Activities that develop mathematical interest in children:

• Creating a Mathematical Corner: Establishing a dedicated area in the classroom for mathematical activities encourages students to explore and engage with math in a hands-on manner. This can include interactive games, puzzles, and math-related resources that make learning enjoyable and accessible.
• Showing Videos of Indian Mathematicians: Introducing students to the lives and contributions of mathematicians through videos can inspire an appreciation for the subject. Learning about real-world applications and the impact of mathematics on society can foster a sense of relevance and interest among students.
• Providing Mathematical Puzzles and Magic Squares: Offering students puzzles and challenges stimulates critical thinking and problem-solving skills. These activities make mathematics more interactive and enjoyable, encouraging students to approach problem-solving creatively and enhancing their interest in the subject.

Hint

• Praising only the student who scores the highest marks may create a competitive environment and potentially discourage other students who may not excel in traditional examinations.

Hence, the correct answer is 'she always praises the student who scores the highest marks in the term-end examination in the class'.
