培养学生的抽象能力,是小学数学教学中的一项重要任务。低年级儿童知识少,概括能力比较差,而数学又具有抽象的特点,要求他们理解抽象的概念往往是很困难的。在教学中我充分利用直观教具,为儿童提供大量的感性材料,使他们能展开思路,提高学习数学的兴趣,在增长知识的同时,培养他们的抽象能力。 Training students' abilities of abstraction is an important task in elementary mathematics teaching. Children in lower grades have less knowledge and abilities to summarize, and mathematics is abstract in character. It is often difficult for them to understand the concept of abstraction. In teaching, I make full use of visual aids to provide children with a large amount of perceptual material so that they can start thinking, improve their interest in learning mathematics, and develop their abstract abilities while increasing their knowledge.
