新课程标准明确指出:“学生的数学学习内容应当是现实的、有意义的、富有挑战性的,这些内容要有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动。”为此,数学课本十分注重从实例出发引入数学问题。然而,如何根据学生所处的实际环境,充分挖掘可以利用的课程资源,给学生提供最有效的学习素材,铸就精彩的课堂呢?笔者认为可以从以下几个方面实现。一、从趣味活动中选择素材,让“死”课堂“活”起来 The new curriculum standard clearly states: “Students ’mathematics learning content should be realistic, meaningful and challenging. These contents should be conducive to students’ initiative in mathematical activities such as observation, experiment, speculation, verification, reasoning and communication . ”To this end, mathematics textbooks put great emphasis on the introduction of mathematical problems starting from the instance. However, according to the students’ actual environment, how to fully tap the available curriculum resources, provide students with the most effective learning materials, and create a wonderful classroom? I believe that the following aspects can be achieved. First, select the material from the fun activities, so that “dead ” classroom “living ” up
