浅谈小学数学教学中“说”的训练

On the primary school mathematics teaching in “said” training

小学数学课堂教学中重视数学语言的训练,有助于学生理解数学专用术语,提高学生数学思维的连惯性和灵活性。可以从以下五个方面着手训练:在教学概念、性质、公式推导时训练学生用数学语言说话;在图文应用题和动手操作题时,训练学生用数学的眼光、专业的数学语言说出图中的信息和操作过程;在用数学解决问题中,训练学生说题意、说思路、说方法、说过程;在计算题练习时有意识地训练学生说算理;在作业订正时说说出错的原因。

The significance of the mathematical language training for primary school mathematics classroom teaching,help students to understand the mathematical terminology,improve students′mathematical thinking inertia and flexibility.It can from the following five aspects of training:in the teaching concept,nature,training students′mathematic formula language;in graphic application problems and hands-on exercises,training students to say the information and operation process chart using mathematical language mathematical perspective,professional;to solve problems with mathematics,focusing on training students said.Thinking,said,said method,said process;there is awareness in the calculation exercises to train the students to say when the algorithm;about the cause of the error in the homework correction.
