First to understand the learning process:
(1)
1.understanding abacus, understand each place name, learn to pose and the right way to hold a pen.
2.0 ~ 10, pan figure, bead like figure, fingering, think of beads and decomposition.
3. Add lapse:
straight first practice on the abacus, add and subtract a hybrid is a single digit 3 ~ 6 pen digit simulation arithmetic double-digit simulation in three digits 2 ~ 3 different Numbers don't carry add and subtract 1.
(2)
1.full five plus, break five minus (five to gather together, gather together to five), grasp the concept of quantity (two together to mutual called primary 5) practice on an abacus mental calculation
2.carry abdication subtraction, master complement concepts (and up to 10 number of two complement each other) abacus mental calculation
(3)
1. The broken 5 carry, abdication five minus
2. Broken 5 carry, abdication minus five mental arithmetic
3. Two digits to add and subtract 3 ~ 5 pen to calculate the pros and cons of abacus mental arithmetic is again said:
a best: to improve memory ability, training attention, bead mental arithmetic speed and accuracy of screw, the key lies in the brain of the length of the time to maintain the abacus, trace depth and so on. 2. To improve computing skills 1, computing power, of course after learning the abacus, looks computing power is raised, very young children to calculate the digits, there is no problem. If to judge computing power, that is, of course, but I not see the calculations. Combined traditional split method is very can improve children's thinking ability, children by looking at the special point in the analysis of the formulas to simplify the operation of thinking ability is not exercise? Learning, of course, the "abacus" at the same time also can learn the traditional, but that doesn't also show that the traditional "abacus" irreplaceable place? If just can calculate one hundred and one thousand - bit arithmetic, I don't see the calculation method of practical significance. 2, attention, of course, can be improved, if he is not concentration, how can in the shape of an abacus is constructed in the heart, 3, and, of course, also can be improved, because he has to remember the bead dial position, or else how can calculation results.
