新课标明确指出: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。内容的呈现应采用不同的表达方式,以满足多样化的学习需求。数学仿佛在许多人心中都是很枯燥与抽象的,但是数学也有感动人的时候,在跟数学的交往中也能品到好多的乐趣。 The new curriculum clearly states: Students should be realistic, meaningful and challenging, and their content should be conducive to students taking the initiative to conduct mathematical activities such as observation, experiment, guesswork, verification, reasoning and communication. Content should be presented in different ways to meet diverse learning needs. Mathematics seems to be boring and abstract in many people’s minds, but mathematics can also bring a lot of fun when it comes to math.
