《数学课程标准》中明确提出:“人人学习有价值的数学,人人都获得必需的数学,人人在数学上得到不同的发展。”这一理念告诉我们,在实际的小学数学教学中,我们一定要立足学生的实际,切实做到以学生为本,尽一切可能激发学生的数学学习兴趣,进而促进学生全面而富有个性的发展。情境教学把复杂的数学教学融入具体的教学情境中,能够有效激发学生对教学活动的强烈兴趣,从而实现教学活动顺利、高效的开展。但是,不同类型 The standard of mathematics curriculum clearly states: “Everyone learns valuable math, and everyone has the necessary mathematics, and everyone has a different development in mathematics.” This philosophy tells us that in the actual elementary mathematics Teaching, we must be based on the actual students, and effectively implement a student-centered, do everything possible to stimulate students interest in mathematics learning, and thus promote the students full and rich personality development. Situational teaching to complex mathematical teaching into specific teaching situations, can effectively stimulate students’ strong interest in teaching activities, so as to achieve the smooth and efficient teaching activities. But different types
