Math knowledge in the first and second grades of primary school is easy to digest. In the past two years, primary school students have basically mastered counting, addition and subtraction within 100, multiplication formula and plane graphics. From the perspective of psychological and thinking development, 8-and 9-year-old children who entered the third grade have initially possessed the ability and conditions to learn and accept logical reasoning, and can accept and understand the thinking and difficulty of Olympic math problems.

Early mathematics enlightenment education covers a wide range, including the concept, set, classification, comparison, ranking, time and space of numbers, as well as the requirements for ability, emotion and attitude. Small class mathematics enlightenment education is to let small class children feel the superficial knowledge of mathematics, carry out preliminary mathematics training, stimulate children's interest in mathematics activities and cultivate children's ability to solve simple problems.

The teaching goal of "seeing cards and putting things" in small classes is: 1. Perceive the number within three, learn the number with the same hand and mouth, and say the total; 2. Learn to place the corresponding number of objects according to the number of cards. For example, the teaching goal of "understanding 1 and many" is to perceive "1" and "many", express the number of objects with "1" and "many" and understand "1".
