数学课程标准的全面实施对学生数学学习的内容提出了新的要求。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。根据这一基本思路,笔者认为要构建小学数学活力课堂,首先应关注小学生课前 The full implementation of mathematics curriculum standards put forward new requirements for the content of students’ mathematics learning. The students ’mathematics learning content should be realistic, meaningful and challenging, which should be conducive to students’ initiative in mathematical activities such as observation, experiment, speculation, verification, reasoning and communication. According to this basic idea, I believe that to build primary school mathematics vitality class, should first pay attention to primary school students before class
