Students' learning is carried out in mathematical activities, such as learning multiplication and division, distribution and so on. Students understand multiplication, division and distribution through mathematical activities such as calculation, observation, thinking and guessing, discovery and verification, and further apply them. Mathematics teaching is to organize students, guide students and participate in mathematics activities.

The real ability of teachers lies not in imparting knowledge, but in stimulating students' learning motivation, arousing students' desire for knowledge, allowing them to participate in the whole teaching process with interest and acquire knowledge through their own thinking activities and hands-on operations. The new curriculum reform has created new opportunities for teachers, "all for students", which will be the goal of teachers' efforts; Giving students freedom will also be the only criterion for teachers to teach. Happy teaching will make teachers and students grow together in teaching, and make students acquire knowledge, cultivate personality and develop healthily in learning.
