应用题作为联系数学知识与现实生活的桥梁,是各项数学知识的整合体现和数学教学的重要组成部分,同时也是数学教学中的一个难点。一年级的应用题教学作为起始,面对的是思维以具体形象为主的学生,如何帮助他们理清数量关系形成解题思路呢?本文尝试给出一些教学建议。一、理解加减法的意义,建立基本的运算模型运算意义的理解是学生解决问题的依据与基础。对于初步接触加、减法的一年级学生来说,加减法的意义既是加减
As a bridge connecting mathematical knowledge with real life, application questions are an integral part of mathematics knowledge integration and mathematics teaching, and are also a difficult point in mathematics teaching. The first grade of applied problem teaching as a starting point, the face of thinking is a concrete image-based students, how to help them sort out the relationship between the number of ways to solve problems? This article attempts to give some teaching suggestions. First, to understand the meaning of addition and subtraction, the establishment of basic computing model Computational meaning of understanding is the basis and basis for students to solve the problem. For the first contact with plus, minus the first-year students, the meaning of addition and subtraction both addition and subtraction
