两步应用题的教学在整个小学应用题教学中处于承上启下功地位。通过教学,引导学生在已学一步应用题的基础上,了解两步应用题的基本特点,理解数量之间的复合关系,掌握分析思考的方法,形成相应的认知结构,那么,继续学习三至四步的复合应用题也就不会感到困难了。因此,搞好两步应用题的教学,历来受到教师们的重视。 解答两步应用题,需要提出一个中间问题,即明确“先算什么”。对小学生来说,这是一个难点,也是解题思维的一个质的飞跃。为了给教学两步应用题奠定坚实的基础,在一步应用题教学的后期,应当有计划地结合教学内容,开展一系
Two-step application of teaching in the entire primary school teaching in the application of Quxing Gong position. Through teaching, students are guided to learn the basic characteristics of the two-step application questions, to understand the complex relationship between the number, to master the analytical thinking method, to form the corresponding cognitive structure, then continue to learn three The four-pronged composite question will not be difficult.
