1设计说明1.1学情分析综合型问题知识容量大、对学生运用知识和数学思想方法分析问题、解决问题的能力要求较高。在中考数学选择题、填空题、解答题中常以“把关题”和“压轴题”的形式出现。中等程度的学生解答综合题的能力比较弱,对综合题普遍存在恐惧心理,甚至放弃解答综合题。综合型问题常见的类型有以下三种:代数综合型问题(方程、不等式与函数)、几何综合型问题(三角形、四边形、圆、图形与变换)、几何与代数结合的综合 1 Design Description 1.1 Analysis of comprehensive analysis Comprehensive knowledge of large problems, students use knowledge and mathematical thinking and analysis of the problem, the ability to solve problems demanding. In the choice of mathematics in the exam, fill in the blank questions, answers to questions often “the title ” and “finale title ” form. Moderate students' ability to answer comprehensive questions is relatively weak, fear of general problems is widespread, and even give up comprehensive questions. There are three common types of synthetic problems: algebraic synthesis problems (equations, inequalities and functions), geometric synthesis problems (triangles, quadrilaterals, circles, graphs and transforms), a combination of geometry and algebra
