1, the examination paper pays attention to the examination of common thinking methods.
For example, the sum of series in fill-in-the-blank questions, linear programming problems, parabolic problems, parametric equations in multiple-choice questions, constant inequalities, and application problems in solving problems, we investigated thinking methods such as classified discussion, combination of numbers and shapes, reduction and estimation. At the same time, solving triangle problems, application problems and analytic geometry problems also put forward higher requirements for candidates' computing ability.
2. The test paper selects realistic materials in the construction and development of Shanghai, writes application questions in novel situations, guides candidates to integrate theory with practice, pays attention to social development, observes the world from a mathematical perspective, and understands the world with mathematical thinking.
202 1 Key Points of Mathematics in Shanghai College Entrance Examination;
1, pay attention to basic concepts.
Starting with the definition of the concept, from the outside to the inside, eliminating the false and retaining the true, and mastering the essential attributes of the concept are the necessary conditions for improving mathematics literacy. In addition, in concept review, we should also avoid patterning and mechanically applying relevant conclusions.
2. Pay attention to the basic theorems and formulas.
Paying attention to the derivation of formulas and the proof of theorems is not only conducive to understanding and mastering theorems and formulas, but also conducive to understanding the relationship between formulas, and can further explore the mathematical ideas contained in formulas, thus becoming a stepping stone for us to solve related problems.
