(四)对教学内容所作调整的理解 教学内容根据教学目的和要求的改变,作了比较大的调整。主要表现在以下几个方面。 第一,四则计算的要求进一步降低。整数四则运算的要求在现行大纲的基础上又有所降低。笔算加减法以三位数的为主,一般不超过四位;而乘除法的一个乘数和除数不超过两位。这样的要求作为小学生学习数学的基本要求,应当是足够了。会三、四位数的加减法应当足可以应付日常生活中的计算。即使是可能遇到五位数的加减法,在会三、
(D) of the teaching content to make adjustments to the understanding of Teaching content according to the purpose of teaching and change requirements, made a relatively large adjustment. Mainly in the following areas. The first and fourth calculation requirements are further reduced. The requirements of the integer four operations have been reduced on the basis of the current outline. The arithmetic addition and subtraction is based on three digits, generally no more than four digits; and multiplication and division of a multiplier and divisor of no more than two. Such a requirement should be sufficient as a basic requirement for pupils to learn mathematics. Will be three or four digit addition and subtraction should be sufficient to meet the daily life of the calculation. Even if it is possible to meet the five-digit addition and subtraction, in three,
