教学目标:1、知识与技能目标(1)通过对实际问题的分析,感受方程作为刻画现实世界有效模型的意义,通过观察、归纳一元二次方程的概念。(2)能对具体情景中的数学信息作出合理的解释,能用方程来描述和刻画事物间的等量关系。2、过程与方法目标体验数学与日常生活密切相关的联系,认识到许多问题可以用数学方法解决,体验实际问题“数学化”的过程。
Teaching Objectives: 1. Objectives of knowledge and skills (1) Through the analysis of practical problems, feel the equation as the meaning of an effective model of the real world, through the observation and induction of the concept of a quadratic equation. (2) It can give a reasonable explanation to the mathematical information in the specific situation, and can use equations to describe and describe the equivalence relation between things. 2, the process and method Objectives Experience mathematics and daily life is closely related to the contact, realize that many problems can be solved mathematically, to experience the actual problem “mathematical ” process.
