由于儿童的认识是从动作开始的,特别是低年级小学生还保留着直观动作思维的形式。因此在教学中,应从直观形象入手,使学生在动手操作中多看、多想、多说、多做,获得多方面的感性认识。重视实际操作,有利于激发学生学习数学的兴趣,发展学生思维能力,更好地掌握基础知识。 Since children's awareness begins with the action, especially in the lower grades, pupils retain the form of intuitive action thinking. Therefore, in teaching, we should start from an intuitive image, so that students in the hands-on look, think, say, do more, access to a wide range of perceptual knowledge. Emphasis on practical operation, is conducive to inspire students interested in learning mathematics, develop students' thinking skills, better grasp the basics.
