The teaching materials and teaching methods of abacus mental arithmetic are composed of abacus mental arithmetic education and primary school mathematics teachers. After eight years of teaching time and summary, they absorbed the achievements of abacus mental arithmetic teaching in the past ten years and formed a unique and novel teaching system.
The happy teaching method without formula pioneered the abacus mental arithmetic teaching method. Using the traditional formula teaching method of situational stories, children's songs and games, children can really master abacus mental arithmetic skills easily and skillfully in happiness.
learning method
In the process of abacus mental arithmetic teaching, abacus is the foundation. Through the operation of true abacus, let learners know the changes and methods of the four operations. With the proficiency of skills, the image in the learner's mind is gradually established, and the function of mental arithmetic is generated through the simulation operation of the image (virtual disk), so the mind is regarded as the advanced performance of abacus calculation. Abacus and mental arithmetic are like human feet, and you can't choose to walk alone.
The study of abacus can master the calculation ability and memory ability skillfully. Representation in memory ability is the most important abacus image in mental arithmetic. In the process of calculation, the bead counting image is instantly transformed from a static bead to many moving beads, which is completed in a very short time. Therefore, the more skilled the abacus skills, the higher the mental arithmetic will be.
Therefore, in the process of learning abacus mental arithmetic, abacus mental arithmetic and mental arithmetic should go hand in hand, laying the foundation first and expressing it immediately after mental arithmetic. When abacus calculation becomes more and more difficult, it will gradually improve, but mental arithmetic can be more smooth and unconstrained. Pay attention to the space of calculation, beyond the limit of abacus, that is, reach the highest realm of learners.
