In mathematics teaching, we should pay attention to the life of growing and growing people, build an open teaching space, and make students truly become spiritual people.

(A use of students' visual perception, so that students can see and think.

Children's memory materials are mainly visual processing, and students prefer vivid, intuitive and colorful pictures. In classroom teaching, teachers should first deeply understand the intention of compiling textbooks, such as the mathematics textbooks published by Beijing Normal University, which provide students with rich picture materials and organically combine drawing with learning knowledge; Secondly, we should make rational use of these pictures, create problem situations and stimulate students' interest in learning; Finally, students should be encouraged to imagine boldly and put forward mathematical problems on the basis of their own understanding.

(B) to mobilize students to accumulate knowledge, so that students can speak and ask questions.

In classroom teaching, teachers should not only carefully design problem situations for students to see and think, but also make full use of students' accumulated knowledge to make students speak and ask questions boldly. Secondly, teachers should help students to extract their understanding of mathematical models from familiar language environment and deepen their mastery of mathematical knowledge through students' oral English. For example, teaching is "different in height". First, two children help a blind uncle cross the road, let the students observe, and then "talk" about who is tall and who is short; Then let the students "compare" the height with each other, let the students observe and understand the essentials and laws of height comparison, and then carry out practical experience; Finally, "do one thing" combined with the specific situation, let students think independently, reason and judge the length of the rope or route and the thickness of the book. In these activities, the results of students' independent exploration or group cooperation need to be communicated in groups or the whole class. Another example is: In the teaching of "Divide Apples", in order to help students master the decomposition and composition of "10", the teacher compiled a children's song "19 19 Good friends, 2,828 holding hands, 3,737 really close, 4,666 walking together, 5666. This teaching method is suitable for children's psychological characteristics and follows children's learning rules, and has achieved good teaching results.

(C) to create an open classroom atmosphere for students to play and activities.

Lively and active is a child's nature. Classroom teaching should conform to students' nature, design teaching from students' hobbies and interests, introduce cartoon images that students like such as "wise old man", "naughty", "smile" and "smart dog" into the classroom, and display activities such as "shooting flowers", "delivering parcels" and "finding friends" that students like, or run through the whole classroom in the form of crossing obstacles. In such a learning atmosphere,
