结合观察图、式指导阅读小学数学教材有图文结合、图式结合的特点,学生要会看教材,必须学会对照图形,对照算式看书的方法。教学有关几何概念,我经常指导学生结合认真观察图形,抓住教材中的关键词、句阅读,理解概念的意义。如教学扇形时,先让学生对图形进行观察、比较,并抓住“顶点在圆心的角”认识圆心角,抓住“圆心角的
Combined with the observation chart, the guidance of reading primary school mathematics textbooks have the combination of graphic and graphic, the combination of features, students want to see textbooks, you must learn to control graphics, control method of reading books. Teaching geometry concept, I often guide students to carefully observe the graphics, grasp the key words in the textbook, sentence reading, understanding the meaning of the concept. Such as teaching sector, let students observe the graphics, compare, and seize the “vertex in the center of the angle” to understand the central angle, to seize the "central angle of the
