【教学内容】教材五下第86、87、88页内容整合【教学目标】1.在学生已经理解方程的意义上,为学生提供素材,从实际情境中,抽象出数量关系,建立沟通已知量与未知量的等量关系,列方程,建立刻画实际情境的数学模型。2.在解决实际问题的过程中,自学理解并掌握形如ax+b=c的方程的解法,会列上述方程解决两步计算的实际问题。3.深刻体会列方程的需求,在求1倍量中需要用到方程的解来思考比较简便,而已知1倍量,用算式解决思考比较简便。 【Teaching content】 Teaching materials five under 86,87,88 Content integration 【Teaching Objectives】 1. In the sense that students have to understand the equation, to provide students with material, from the actual situation, abstract the number of relations, the establishment of communication known The relationship between quantity and unknowns, column equations, to establish a mathematical model to describe the actual situation. 2. In the process of solving practical problems, self-study to understand and master the form of ax + b = c solution, will be listed in the above equation to solve the practical problem of two-step calculation. 3 profound understanding of the needs of the column equation, in order to seek 1 times the amount of need to use the equation solution to think is relatively simple, and known 1 times the amount, using equations to solve thinking is relatively simple.
