在小学阶段几何初步知识的教学中,小学生受空间观念和空间想象能力的限制,不容易理解和掌握。为此,应充分发挥多媒体教学形象、直观、生动等多方面优势,及时有效地对几何形体的知识点进行分解、组合、分析,使学生从观察到认识,从认识到理解,从理解到掌握,进而提高数学教学质量。 In the elementary elementary geometry teaching, primary school students are not easily understood and mastered by the space concept and space imagination ability. Therefore, we should give full play to multimedia teaching image, intuitive, vivid and many other advantages, the timely and effective decomposition of the geometric knowledge points, combination, analysis, so that students from observation to understanding, from understanding to understanding, from understanding to grasp , And then improve the quality of mathematics teaching.
