观察是学生认识世界、获得知识的基本能力,是发展智力的基础;不会观察,就不可能有丰富的想象和创造性的思维。在小学数学教学中如何培养学生的观察能力呢? (一)顺序观察法。就是教师有目的地设计一些图题,引导学生按顺序、有条理地观察,使学生掌握不漏、不重复地回答问题的方法。例一:下面图中有多少条线段? 例二:在∠AOB内,有4条从O点出发的射线,这里面一共有多少个角?
Observation is the basic ability of students to know the world and gain knowledge. It is the basis for developing intelligence. Without observation, there can be no rich imagination and creative thinking. In primary school mathematics teaching how to develop students' observation ability? (A) sequential observation method. That is, teachers have purposely designed some pictorial questions to guide the students to observe in an orderly and orderly manner, so that the students can grasp the method of answering questions without repetition. Example 1: How many lines are in the image below? Example 2: In ∠AOB, there are 4 rays starting from point O. How many corners there are in total?
