数学课程标准的总目标明确指出:通过义务教育阶段的数学学习,学生能够初步学会运用数学的思维方式去观察、分析现实社会,去解决日常生活中和其他学科学习中的问题,增强应用数学的意识。这一目标的提出,要求我们教育者在平时的教学过程中,不仅要注重学生数学知识的传授,更要关注学生数学素养的培养。我们在平时的教学中会发现,很多学生,尤其是高年级学生具备了初步的问题意识,他们在不经意间会运用数学的眼光去观察生活现象,并且去思考,去分 The general goal of mathematics curriculum standards clearly states: Through the mathematics learning in the compulsory education phase, students can initially learn to use mathematical thinking to observe and analyze the real world, to solve problems in daily life and other subject learning, and to enhance the application of mathematical awareness. Put forward this goal, require our educators in the usual teaching process, not only to pay attention to the teaching of mathematical knowledge of students, but also to pay attention to the cultivation of students’ mathematical qualifications. In our usual teaching, we find that many students, especially those in senior grades, have initial problem awareness. They inadvertently use mathematics to observe the phenomenon of life and think and go
