1, activity preview

Active preview can not only know the content of the class in advance, but also be targeted when attending classes, and can also exercise children's autonomous learning ability.

Specific methods: read the textbook carefully, learn to read under the guidance of the teacher, and preview with the thinking questions carefully designed by the teacher. When you teach yourself examples, you should find out what the examples are about, what the conditions are, what you want, how to answer them in the book, why do you answer them like this, whether there are new solutions and what the steps are.

2. Master the thinking method.

Some students are familiar with formulas, properties and rules. But when they encounter practical problems, they don't know how to apply what they have learned to solve them. Although students remember the formula for calculating the volume clearly, many students can't figure out the way to solve the problem because the problem involves a wide range of knowledge and requires students to gradually master the thinking method when solving the problem under the guidance of the teacher.

3. Master the thinking method.

Generally speaking, there are rules to follow in solving mathematical problems. When solving problems, we should pay attention to summing up the law of solving problems. After solving each exercise, we should pay attention to reviewing the following questions:

(1) What is the most important feature of this problem?

(2) What basic knowledge and graphics are used to solve this problem?

(3) How do you observe, associate and transform this problem to achieve transformation?

(4) What mathematical ideas and methods are used to solve this problem?

(5) Where is the most critical step to solve this problem?

(6) Have you ever done a topic like this? What are the similarities and differences between solutions and ideas?

How many solutions can you find to this problem? Which is the best? What kind of solution is a special skill?

4. Broaden the thinking of solving problems

In teaching, teachers often set questions for students, ask questions and inspire students to think more. At this time, students should actively think and broaden their thinking, so that the broadness of thinking can be better developed. Inspire students to think more, communicate the vertical and horizontal relationship between knowledge, change the method of solving problems, broaden students' way of thinking and cultivate students' flexibility of thinking.
