Parents and teachers should care about mental arithmetic, particularly Grade 1 addition and subtraction, because it lays the foundational skills necessary for future academic success and supports overall cognitive development. During these early years, children are developing essential neural pathways in their brains, and practicing mental math helps strengthen these connections. Proficiency in mental arithmetic fosters better problem-solving skills, enhances memory, and boosts confidence in children, making them more prepared to tackle complex mathematical concepts as they progress in their education.

Mental arithmetic encourages a child's ability to think quickly and logically, which benefits their academic performance across all subjects. It helps children to develop a refined number sense, enabling them to understand the relationships between numbers deeply, and to perform calculations with ease. This confidence in manipulating numbers mentally also translates into improved performance in real-world scenarios, such as handling money, time, or quantities in everyday tasks.

Moreover, involving both parents and teachers in nurturing these skills builds a supportive learning environment, encouraging children to develop a positive attitude towards mathematics early on. This collective effort not only enhances the child's learning experience but also builds a community that values and proactively supports education and cognitive development from an early age.
