There are two lines in our mathematics teaching, one is the teaching of mathematical knowledge of open lines, and the other is the teaching of mathematical thinking methods of dark lines. Mathematical thinking method is the essence of mathematics, the link for students to form a good cognitive structure, the bridge for transforming knowledge into ability, and the carrier for cultivating students' good mathematical literacy and innovative thinking.

Then I will talk about my own ideas on "effectively infiltrating mathematical thinking methods in wide-angle teaching of mathematics"

"Mathematics Wide Angle" is a new characteristic section in the textbook of People's Education Edition of the new curriculum standard, which has been added since the first volume of the second grade. It is a new attempt made by the new textbook in infiltrating mathematical thinking methods into students. Its purpose is to present some important mathematical thinking methods through the simplest examples in students' daily life, and to solve these problems through intuitive means such as operation, experiment and guess.
