在小学几何初步知识教学中,要尽量结合实际引导学生对实物和图形进行观察、比较和测量,把握事物间的逻辑联系,促使学生生动活泼地、独立地进行学习。一、指导记录教学“长方体的体积”时,我根据教学内容,指导学生进行直观演示,并做好观察记录,放手让学生自己探求新知。1.取出6个棱长1厘米的方木块让学生摆一个长、宽、高都不相等的长方体;

In primary geometry teaching, we should try our best to guide students to observe, compare and measure physical objects and figures as far as possible and grasp the logical connection between things so that students can learn vividly and independently. First, the guidance of teaching “cuboid volume”, I based on teaching content, guiding students to conduct an intuitive demonstration, and make observations, let the students to explore their own knowledge. 1.
