《数学课程标准》指出,估算在日常生活与数学学习中有着十分广泛的应用,培养学生的估算意识,发展学生的估算能力,让学生拥有良好的数感,具有重要的价值。有人统计,在实际生活中应用估算的机会比应用精确计算的机会要多得多。
The Mathematics Curriculum Standard states that estimation plays a very important role in daily life and mathematics learning. It is of great value to develop students ’estimation awareness, develop students’ estimation ability and make students have a good sense of number. According to some statistics, there are far more opportunities to apply estimates in real life than to apply accurate calculations.
