小学数学教学的关键就是为学生打开最初的逻辑思维能力,尤其是几何学习,更是对小学生空间想象能力的一种锻炼。所以对于初步接触几何学习的学生而言,教师对几何知识的掌握及运用就变得格外重要,既要兼顾小学生对知识的理解能力,又要最大限度地将几何这门学科的特色展现出来,让学生能够兴致勃勃地接受。 Primary school mathematics teaching is the key to open the students first logical thinking ability, especially geometric learning, but also on the pupils spatial imagination a kind of exercise. Therefore, for the students who are initially exposed to the geometric learning, teachers ’mastery and application of the geometric knowledge becomes especially important. It not only considers the elementary students’ ability to understand the knowledge, but also displays the characteristics of the geometry as much as possible, Allow students to be cheerfully accepted.
