摘要
数感是建立明确的数概念和有效地进行计算等数学活动的基础,数感的培养在数学学习中是贯穿始终的。借鉴孔子的"过而知之"和老子的"无为而治"的思想,在小学数学教学中,让学生感受生活数学,体验数据大小,经历估算过程,从而启蒙、建立、内化学生的数感;让学生参与实践活动,鼓励大胆猜想,自觉质疑反思,以达到发展、深化、提升学生数感的目标。
Number Sense is the base to establish a clear concept of number the calculation activities. The training of number sense should pervade math learning from Confucius "knowing after action" and Lao Tzu's "inaction" teaching in primary schools to enable students to experience mathematics in life, and effectively carry out learning consistency. By thinking in mathematics data size and estimating process, thus to enlighten, establish, internalize the students' number sense; let students participate in practical activities, encourage bold conjecture and conscious reflection in order to meet the goals of developing, deepening and enhancing students" number sense.
