二、观察与实验是探索、发现、解决问题的基础(上)观察是人们对事物或问题的数学特征通过视觉获取信息,并运用思维辨认其形式、结构和数量关系,从而发现某些规律或性质的方法.在数学知识的发现和解决问题的过程中,观察法也是常用的有效方法之一.请看下例.例1下图表示2m的个位数
2. Observing and experimenting is the basis for exploring, discovering, and solving problems (above) Observing that people visualize information on the mathematical features of things or problems by visually acquiring information and using their thinking to identify their relationships in terms of form, structure, and quantity, thus finding certain patterns or The method of nature. In the process of discovering and solving problems of mathematics knowledge, observation method is also one of the commonly used effective methods. Please see the following example. Example 1 The following figure shows the single digits of 2m.
