Parents and teachers should care about mental arithmetic for children aged 4-9 because it builds a critical foundation for future learning and cognitive development. During these formative years, children’s brains are highly receptive and adaptable, making it an ideal time to develop key skills. Mental arithmetic enhances a child's number sense, enabling them to understand and manipulate numbers, which is essential for more complex math problems in higher grades. Furthermore, solving arithmetic problems in their head improves working memory, concentration, and problem-solving skills.

Incorporating mental arithmetic also encourages faster thinking and better decision-making, crucial abilities both in and out of the classroom. These skills benefit children in everyday situations, from calculating change during shopping to sharing items fairly among friends. Moreover, early success in arithmetic can boost a child’s confidence and reduce math anxiety, fostering a positive attitude toward the subject.

Teachers who integrate mental arithmetic into their lessons provide stimulating and varied learning experiences that keep young minds engaged. Similarly, parents who encourage practice at home reinforce this learning, creating a well-rounded and supported educational environment. Overall, mental arithmetic at a young age prepares children for academic success and equips them with skills valuable for lifelong learning.
