Mental math practice in addition and subtraction is crucial for children aged 8-9 as it lays the foundation for more complex mathematical concepts. At this stage, children are developing their problem-solving skills, and enhancing their mental arithmetic fosters numerical fluency. By practicing these skills, children learn to perform calculations quickly and efficiently, making them more confident in their mathematical abilities.

Engaging in mental math exercises helps reinforce number sense, which is vital for understanding relationships between numbers. This practice boosts cognitive skills, particularly working memory and concentration. Additionally, mental math enhances critical thinking, as children learn to choose strategies that best fit the problems they encounter.

For parents and teachers, supporting mental math practice not only aids academic performance but also cultivates a positive attitude towards math. Children who feel confident in their math skills are more likely to participate and excel in future mathematical discussions and activities.

Moreover, mental math practice is an effective way to prepare for standardized tests, where problem-solving speed often counts. By integrating fun mental math exercises into daily routines, parents and teachers can make learning enjoyable, thereby fostering a lifelong appreciation for mathematics and enhancing overall academic success.
