在小学数学教学中,教师不仅是数学知识、技能的传授者,更是数学思想方法的传播者。教师应挖掘数学教材的资源,借用数学广角活动,于解题过程中渗透数学思想方法,提高学生的数学素养。研读教材,把握教学目标数学思想方法需要学生在不断实践中体验感悟,数学思想方法的渗透需要经历一个长时间的过程。教材中数学广角内容的编排采用螺旋上升的原则,旨在有步骤地渗透数学思想方法。因此教师要梳理整套教材,进行横向比较和纵向比较,在认 In elementary mathematics teaching, teachers not only teach maths knowledge and skills, but also disseminate math thoughts and methods. Teachers should tap the resources of mathematics teaching materials and borrow the wide-angle activities of mathematics to infiltrate the mathematical thinking and methods during the process of problem solving so as to improve their mathematical literacy. Studying teaching materials, teaching objectives to grasp the mathematical thinking methods require students to experience in constant practice sentiment, mathematical thinking and methods of infiltration need to go through a long process. Textbook math wide-angle content arrangement using the spiral principle, designed to infiltrate the method of mathematical thinking step by step. Therefore, teachers should sort out the whole set of teaching materials for horizontal comparison and vertical comparison
