First of all, from the content, primary school mathematics mainly includes basic knowledge such as addition, subtraction, multiplication and division, fractions, decimals and geometric figures, while junior high school mathematics is more in-depth, including algebra, functions, probability, statistics and other more complex knowledge. Primary school mathematics pays more attention to the mastery and application of basic knowledge, while junior high school mathematics pays more attention to the cultivation of logical reasoning and abstract thinking.
Secondly, from the difficulty point of view, the difficulty of primary school mathematics is relatively low, mainly to cultivate students' basic computing ability and logical thinking ability. The difficulty of junior high school mathematics is obviously improved, which requires students to have strong abstract thinking ability and logical reasoning ability. For example, problems in primary school mathematics can usually be solved in an intuitive way, while problems in junior high school mathematics need to be solved with abstract symbols and formulas.
Furthermore, from the method point of view, primary school mathematics mainly adopts intuitive teaching method, which helps students understand and master knowledge through intuitive ways such as objects and pictures. And junior high school mathematics uses deduction and induction to teach knowledge through deduction and proof. This method requires students to have strong logical thinking ability and abstract thinking ability.
Generally speaking, the main difference between primary school mathematics and junior high school mathematics lies in the depth and breadth of content, the size of difficulty and the different teaching methods. Elementary school mathematics is the foundation of junior high school mathematics. Only by mastering the knowledge of primary school mathematics can we learn junior high school mathematics better.
