Extended data
The logical structure and subject characteristics of mathematics itself determine that mathematics contains more than just calculation skills. Too much emphasis on calculation and a lot of pre-calculation training often cause children's resistance to mathematics, and mathematics learning becomes a burden. Both teachers and parents need to update this concept and explore ubiquitous mathematical concepts in a wider range from the subject characteristics of mathematics itself, such as the concepts of counting and number, calculation, measurement, graphics and space, charts, classification and models, which should be involved in kindergarten mathematics education.
