一、学会动手,化无形为有形小学数学问题具有较强的抽象性和逻辑性,而小学儿童,特别是低年级儿童,他们的思维仍然以具体形象思维为主要形式,他们的抽象逻辑思维需要在感性材料的支持下才能进行。因此,引导学生在操作活动中学会化归,既是学生由形象思维向抽象思维发展的需要,又是他们解决抽象的数学问题的需要。1.实践操作例如同学们排队,笑笑的前面有6人,笑笑 First, learn hands-on, invisible For the tangible elementary mathematics problem has a strong abstract and logical, and primary school children, especially children in the lower grades, their thinking is still the main form of concrete image thinking, their abstract logical thinking needs Only with the support of sensuous materials can be carried out. Therefore, to guide the students to learn and return in the operational activities is not only the need of the students to develop from the image thinking to the abstract thinking, but also the need of them to solve the abstract mathematical problems. 1. Practice For example, students line up, laughing in front of six people, laughing
