2. The degree of students' participation in learning.

3. The display space of students' innovative consciousness and exploration spirit.

4. Master basic knowledge and skills.

5. Students' ability to use mathematical knowledge to solve problems around them.

Teachers should encourage students to think independently, learn from each other and dare to express new ideas and practices. Only by truly forming an open classroom and designing open questions can students take the initiative to participate and cultivate their awareness of exploration, innovation and practice. Primary school mathematics should be regarded as applied mathematics rather than pure mathematics, and abstract book contents should be visualized and boring exercises should be gamified in teaching; Let students use mathematical thinking methods to solve the problems around them and feel that learning mathematics is the need of life. Change "I want to learn math" to "I want to learn math".
