1, master the comparison method.
When comparing weights, a simple balance is usually used. When a balance is balanced, the objects at both ends are equally heavy. The sky is unbalanced, the sinking end is heavy and the upturned end is light. When comparing several objects, we can compare two of them first and then compare the third.
2. Be reasonable.
Comparatively speaking, besides careful observation, it is more important to learn simple reasoning initially. For example, a carrot is as heavy as three carrots, so it can be inferred that a carrot is definitely heavier than a carrot. Developing reasoning ability and choosing strategies flexibly according to the actual situation can make comparison faster and simpler.
Extended data:
The ultimate goal of learning concepts is to solve specific problems with concepts. A comprehensive and accurate understanding of mathematical concepts without prejudice is conducive to using the learned mathematical concepts to analyze and solve related mathematical problems. With clear mathematical concepts, students' reading ability can be improved rapidly, and with the accumulation of concepts, students' comprehensive ability can be by going up one flight of stairs.
When the concept is mastered to a certain extent, students will have the idea of reasoning, consciously transfer knowledge and cultivate the ability to solve problems. In mathematics learning, by comparing similar concepts or laws, we can find out their similarities and differences and connections, so as to deepen our understanding and memory of them.
Clear the relationship between mathematical knowledge, deeply understand the concept of mathematical knowledge, understand the derivation process of mathematical knowledge, and make knowledge orderly and systematic, so it is very important to learn mathematics, remember and correctly describe concepts and laws.
The ambiguity of knowledge is the most taboo in mathematics learning, and the knowledge points are confused. In order to avoid this situation, students should learn to write "summary of knowledge structure", learn to divide and combine questions, learn to analyze and solve typical problems from multiple angles and aspects, and summarize basic questions and basic laws and methods.
