新课程标准指出课程内容的学习,强调学生的教学活动,发展学生的推理能力,让学生能清晰、有条理地表达自己的思考过程,做到言之有理,落笔有据;在和他人交流的过程中,能运用数学言语合乎逻辑地进行讨论与质疑。因此,培养小学生数学数量关系的推理能力对培养学生的数学问题意识和创新精神起着抛砖引玉的作用。数学能力的结构特点是严谨的,逻辑性强。数学是培养推理能力的最好学科,而推理能力的强弱也是数学能力发
The new curriculum standard points out the learning content of the course, emphasizing the teaching activities of the students, developing students’ reasoning abilities, enabling students to express their thinking process in a clear and orderly manner, making reasonable excuses, and communicating with others In the process, it is logical to use mathematical language to discuss and question. Therefore, the reasoning ability to cultivate the relationship between the number of pupils in mathematics plays a valuable role in cultivating students’ consciousness and innovative spirit of mathematics. The structural features of mathematical ability are rigorous and logical. Mathematics is the best discipline to develop reasoning ability, and the strength of reasoning ability is also a mathematical ability
