In the senior high school entrance examination, the first thing is to test basic knowledge and skills. The full score of the mathematics senior high school entrance examination questions is 120, in which the score ratio of easy questions, medium questions and difficult questions is approximately 7:2: 1, and the easy questions and most medium questions are for testing basic knowledge and skills. If you get all these questions, your grades will not be too low.
2. Pay attention to application
The application problem with the goal of "solving simple practical problems" is the focus and difficulty of junior high school mathematics, and it is also a hot spot in the senior high school entrance examination in recent years.
For example, in order to alleviate the problem of "parking difficulty", a company plans to build an underground parking garage, and the architect provides a schematic diagram of the underground parking garage (as shown in the figure). According to the regulations, the height limit sign should be posted above the ramp of the underground parking garage to inform the parking person whether the vehicle can enter safely. Indicate the height limit, please calculate the height according to the figure, and the accuracy is 0. 1m).
Hugging: The biggest application of equation thought is to solve practical problems with equations. It should be noted that the obtained solution must conform to the practical significance, that is, it needs to be tested.
3. Focus on innovation and openness
The outline points out: "The innovative consciousness to be cultivated in junior middle school mathematics mainly refers to: being curious about the phenomena in nature and society, constantly pursuing new knowledge, thinking independently, finding and putting forward problems from the perspective of mathematics, and exploring, studying and solving problems with mathematical methods".
4. After solving the problem, we should reflect on it from six aspects:
Think about cause and effect, laws, solutions, flexibility, classification and mistakes.
5. Pay attention to mathematical thinking methods and improve problem-solving ability.
Mathematical thinking method is the bridge and link between knowledge and ability. The idea of transformation and reduction (elimination method, reduction method, undetermined coefficient method), the idea of function and equation, the combination of numbers and shapes, and the idea of classified discussion are all compulsory contents in the annual senior high school entrance examination.
