1, concept discrimination method. If a concept is given in the judgment question, we should learn to analyze and distinguish it with the concept in the textbook.
2. Enumeration method. List all kinds of situations according to the description in the judgment question to see if there are any examples that conflict with the topic.
3. Hypothetical method. According to the description in the judgment question, suppose one of the quantities and find out the other quantities. If there is a contradiction with the conclusion in the judgment question, then the whole judgment question is wrong.
4. Calculation method. If we need to calculate the content given in the judgment question, then we might as well do it ourselves and see if the conclusions are consistent.
5. Method of operation. Verify the conclusion by drawing or hands-on operation.
Judgment is a form of thinking that affirms or denies an object and its attributes. In the study of mathematics, it is often necessary to give a positive or negative answer to the spatial form and quantitative relationship of the real world, so it is necessary to widely use judgments and take some correct judgments as the basis for further research. Definitions, laws and formulas in primary school mathematics are all judgments. Judgment is composed of concepts, and it is a form of interrelated concepts. Any judgment is a student's understanding of mathematical knowledge and a reflection of the relationship between mathematical knowledge.
