1. Kindergarten stage (0-6 years old):
In kindergarten, children are usually not exposed to formal mathematical concepts, but they can start simple abacus mental arithmetic training. This stage of abacus mental arithmetic is mainly to cultivate children's perception of numbers and basic calculation skills. By using concrete objects such as beads, children can feel numbers in many ways such as vision and touch, and perform simple addition and subtraction operations.
2. Lower grades of primary school (6-9 years old):
As children enter the lower grades of primary school, they begin to get in touch with more in-depth mathematical knowledge and concepts, which is an ideal opportunity to learn abacus mental arithmetic. At this stage, mental arithmetic can help children improve their calculation speed, accuracy and concentration. Through abacus mental arithmetic training, children can develop good calculation habits and mathematical thinking ability, and lay a solid foundation for higher-level mathematics learning in the future.
3. Upper primary and secondary schools:
Abacus mental arithmetic can still be used as an auxiliary tool to help students improve the efficiency and accuracy of calculation. At this point, the training focus of abacus mental arithmetic can gradually shift to more complex operations, such as multiplication, division and square. Through constant practice, students can quickly complete calculations in their usual hands, thus improving the speed and accuracy of solving mathematical problems.
4. University and workplace applications:
Abacus mental arithmetic is still a valuable skill for those who have a strong interest in mathematics or work related to numbers. During college study, abacus mental arithmetic can help students better understand and apply abstract mathematical concepts and improve their problem-solving ability. In the workplace, mental abacus calculation can help people calculate quickly and accurately in their daily work and improve work efficiency.
5. Conclusion:
Generally speaking, it is best to learn abacus mental arithmetic from kindergarten or the lower grades of primary school. Children at this stage are easy to accept new knowledge. Abacus mental arithmetic can effectively improve children's computing ability and mathematical thinking ability, and lay a solid foundation for their future study and career development. Whether in school or in the workplace, it is very beneficial to master abacus mental arithmetic.
