计算能力既是小学生必须具备的基本技能,也是今后学习数学的基础。坚持指导学生在算前算后估算,将估算内化为一种自觉意识,养成良好的估算习惯。通过学生的独立思考,产生不同的算法,既让学生体验解决问题策略的多样性,又体现学生的个性。理解运算道理,掌握计算方法,形成良好的数感,养成良好的学习习惯,从根本上提高计算教学的质量。
Calculating ability is not only the basic skills that pupils must possess, but also the basis for learning mathematics in the future. Adhere to guide students in the calculation before the calculation, the internalization of the estimate as a conscious, to develop good estimation habits. Through the students’ independent thinking, they produce different algorithms, which not only allow students to experience the diversity of strategies to solve problems, but also reflect the personality of students. Understand computing principles, master the calculation method, form a good sense of number, develop good study habits, and fundamentally improve the quality of teaching.
