The earliest mathematical ability is the ability of unsigned number sense. From our adult point of view, the range of quantity can be the range of sensory quantity, that is, 1-3 objects, which is the range of quantity that can be known at a glance; Figure 1 The brain regions activated by adults and 4-year-old children are very similar when dealing with unsigned (physical) quantities, and they can be counted, that is, four or more, but you need to count them to know how many.
According to foreign research, babies born 4~6 months can accurately distinguish the number of smaller objects (2 and 3). Later, another study showed that 7-month-old babies can match the number of objects seen by their eyes with the number of sounds heard by their ears. For example, in the experiment, when the drum sounds twice, the baby looks at two objects for longer than three objects.
Children's due math scores;
1 year-old and 0-6-year-old are critical periods for the development of children's brain structure. Without proper and moderate cognitive activities, structural development will be affected. For example, dyscalculia in primary schools is often related to hypoplasia of the parietal lobe. Carrying out the auxiliary teaching of abacus calculation in the lower grades of primary schools can eliminate the obstacles in calculation. If there is proper math training in early childhood, it may promote the development of parietal lobe.
2. The sense of unsigned number may be innate, but the sense of signed number, counting and calculating ability are formed through a lot of training, which can be in life or deliberately set; In early childhood, with the development of language ability, it is the necessary basis for subsequent school education.
3. Spatial ability is the basis of the development of mathematical ability, which can be included in the category of mathematical ability in essence, and its development has laid the foundation for school mathematics education.
