A number concept which has been developed by humankind, is one of culture and a number is deeply relation with human life. We study the number concept which consist in mental arithmetic, written arithmetic and estimation with integer, decimal and fraction numbers, especially under the changing society of higher technical information processes.We can find new suggestions for the teaching of 'number and computation' through computer: student's concept of number and computation is developed more wider and higher than no using computer, in this case it is important aspect for student to use an idea of estimation on problem solving in mathematics classroom activities.

数是人类发展起来的一种文化概念，数与人类生活有着密切的联系。通过对心算、笔算、整数、小数、分数估计中的数概念的研究，特别是在高科技信息处理的社会变革中，对“数与计算”的计算机教学提出了新的建议：学生的数的概念和计算的概念比不使用计算机时发展得更广、更高，在这种情况下，在数学课堂活动中，学生运用估计思想解决问题是一个重要方面。
