《小学数学课程标准》中强调:学生的数学学习活动应当是一个生动活泼的、主动的和富有个性的过程;从学生已有的生活经验出发,让学生能独立的进行实际问题的应用,从而使得抽象的数学模型能够得到形象化;在自主探究与合作交流的阶段中,能够将数学知识以及技能掌握。在教学过程中,需要不断地激发学生们学习的积极性,要不断创造条件,让学生能够获得自我展示的机会,让学生能够在掌握学习规律的同时,还能够发挥出主观的能动性,只有这 “Primary Mathematics Curriculum Standard” emphasizes: students ’mathematics learning activities should be a lively, active and personalized process; starting from the students’ existing life experiences, allowing students to independently carry out practical problems so that Making the abstract mathematical model can be visualized; in the process of independent exploration and cooperation and exchange, can grasp the mathematical knowledge and skills. In the process of teaching, students need to constantly stimulate the enthusiasm of learning, we must continue to create the conditions for students to be self-presenting opportunities for students to master the law of learning at the same time, but also be able to play a subjective initiative, only this
