Parents and teachers should prioritize mental math skills, especially in normal addition and subtraction for children ages 7-9, as these foundational skills are essential for academic success and daily life. At this age, children are developing their mathematical reasoning and problem-solving abilities. Mastering mental math enhances speed and accuracy, allowing students to solve calculations quickly, which builds their confidence and encourages a positive attitude toward math.

Moreover, mental math fosters critical thinking, enabling children to approach more complex mathematical concepts later in their education. It cultivates flexibility in thinking; children learn various strategies for solving problems, enriching their cognitive processes. This flexibility is particularly useful for adapting to new problems and challenges.

In addition to academic benefits, strong mental math skills support everyday tasks—from managing allowances and budgeting to understanding time and measurement—helping children gain practical life skills. Supporting mental math in the classroom and at home lays the groundwork for a solid mathematical foundation and promotes a lifelong appreciation for numbers. Engaging children in fun activities, games, and everyday math conversations makes learning enjoyable, ensuring they develop resilience and a positive mindset towards mathematics.
