数学源于生活、用于生活。把数学和生活实践联系起来,能使学生在不知不觉中感悟数学真谛,学会用数学的思想方法去观察和认识客观世界,从而促进学生的思维向科学的思维方式发展。因此我根据教材的特点,结合学生的生活经验和知识背景,开展生动、有趣、直观的数学活动。 Mathematics comes from life, for life. By linking mathematics and life practice, students can unknowingly realize the essence of mathematics, learn to use mathematical thinking methods to observe and understand the objective world, so as to promote students’ thinking to develop in a scientific way of thinking. Therefore, according to the characteristics of teaching materials, combined with the students’ life experience and knowledge background, I carry out vivid, interesting and intuitive mathematical activities.
