The seventh grade first volume mathematics unit reexamination.
Set and correspondence thinking, classified discussion thinking, combination of numbers and shapes thinking, movement thinking, transformation thinking and transformation thinking. With mathematical ideas, we should master specific methods, such as method of substitution, undetermined coefficient method, mathematical induction, analysis, synthesis and induction. In terms of specific methods, commonly used are: observation and experiment, association and analogy, comparison and classification, analysis and synthesis, induction and deduction, general and special, finite and infinite, abstraction and generalization. When solving mathematical problems, we should also pay attention to solving the problem of thinking strategy, and often think about what angle to choose and what principles to follow. The commonly used mathematical thinking strategies in senior high school mathematics include: controlling complexity with simplicity, combining numbers with shapes, advancing forward and backward with each other, turning life into familiarity, turning difficulties into difficulties, turning retreat into progress, turning static into dynamic, and separating and combining. 3. Gradually form a "self-centered" learning model. Mathematics is not taught by the teacher, but under the guidance of the teacher.
