Parents and teachers should prioritize mental math skills, particularly addition and subtraction, for 9-year-olds because these skills are foundational for a child's overall mathematical development and confidence. At this age, children are moving beyond concrete math concepts and are expected to apply logical reasoning and critical thinking to solve problems more efficiently. Mastering mental math can lead to enhanced problem-solving skills, making math feel less intimidating and more accessible.

Moreover, mental math fosters cognitive flexibility, enabling kids to approach mathematical challenges in various ways. As students encounter more complex math tasks in the years to come, a strong ability to perform addition and subtraction mentally will simplify higher-level calculations and improve long-term academic performance.

Additionally, anytime a child calculates amounts while shopping, or estimates time for a travel, they are applying these skills practically. Building mental math proficiency helps boost self-esteem, enabling kids to approach math with a positive mindset rather than fear. Furthermore, these skills cultivate a sense of independence in learning; rather than relying solely on calculators, students can develop a natural competency with numbers that will serve them throughout their educational journey and everyday life.
