What's the difference between a child prodigy's hand-brain quick calculation and abacus mental calculation?

Fast calculation of neck, hands and brain, abacus mental arithmetic

Eyes, ears, mouth, hands and brain are involved at the same time.

discrepancy

Learning tools don't need any abacus.

Once the conditions of two-handed operation, double brain counting and hand-brain are formed, they will never be forgotten. Memory with brain images, with the growth of children's age, brain images slowly disappear and are easy to forget.

The difficulty is simple, the formulas are few, the homework is not complicated, there are many formulas, and there are many homework.

Classroom features through games, stories, music and other multiple intelligent training, teacher-student interaction, active classroom. Mainly using abacus, the classroom is boring.

Cultivate the goal to improve the calculation ability and develop the whole brain potential at the same time. Improve computing power.

The potential development principle is that the hands are constantly stretched and flexed, which promotes the increase of cerebral blood flow, activates brain cells and promotes quick thinking. Through continuous abacus calculation, brain image memory is formed.
