几何图形包括平面图形和空间图形,它们不仅在生活中随处可见,同时也是数学中重要的组成部分,特别是同数形结合的数学思维联系起来,几何也就成为了数学实际应用过程中必须涉及的内容之一。小学数学中的几何教学是几何的开篇,也是几何的基础。这个时期的几何可以称作是一种建立于“经验”之上的几何,要想提高小学生几何基础的学习质量和解决几何习题的能力,就要从强化学生的几何基础概念以及培养其灵活严谨的解题思想等方面入手。一、根据经验,强化基础概念几何图形其实就存在于学生们的脑海里,它们都来自日常生活中所见到的事物。教师可以由此展开,修正日常认知中的一些错误,增加学生对几何的熟悉度,降低学习的抵触
Geometrical figures include plan and space figures. They are not only seen everywhere in life but also an important part of mathematics. Especially in connection with the mathematics thought of combining figures, geometry has become a must in mathematics practice. One of the content Geometry in elementary mathematics teaching is the beginning of geometry, but also the basis of geometry. The geometry of this period can be called a geometry based on “experience ”, in order to improve the quality of primary school students learning geometry and the ability to solve geometric problems, we must strengthen students from the geometric concept of basic and develop their Flexible and rigorous problem-solving ideas and so on. First, based on experience, to strengthen the basic concepts of geometry actually exist in the minds of students, they are from everyday life to see things. Teachers can thus start to correct some mistakes in daily cognition, increase students’ familiarity with geometry and reduce the conflict of learning
