If you think you can learn addition and subtraction within 100, even if you are good at math, I think it is a bit narrow. Arithmetic is the study of numbers and their operations, but mathematics is much more extensive than arithmetic. Simply put, mathematics includes everything, but it is more extensive than all this. Number and shape are two cornerstones. The following are some suggestions for the development of mathematics cognition in preschool stage.

① quantity

Numbers are everywhere in life and have different forms. Let's broaden children's cognitive range of numbers.

What bus do you take today? 325, what is the reciprocal of this string of numbers?

② shape

Observe with eyes, touch with hands, think with brains, encourage children to ask questions, and establish preliminary spatial geometry cognition. Children, have you ever played with building blocks? Think about the characteristics of these shapes. Can you tell them the differences or similarities?

Train children's observation ability by finding different kinds of problems, and cultivate children's graphic cognition and graphic combination ability by building blocks, jigsaw puzzles.

③ Other cognition

Know left and right, up and down, back and forth, etc. Know odd and even numbers, know weight, know time, know mirror symmetry, observe objects, know coins, know length, size and so on. Anytime, anywhere is a classroom, as long as parents are willing to pay attention.
