一教科书的修订情况本次主要从调整单元结构、增强内容与习题的关联度、加强数学思考和数学活动、重构问题解决编写体例等方面对原教科书进行了修订。1.适当调整了单元结构。(1)将“分数”单元“约分”“通分”小节中公因数、公倍数的内容,调整到第一单元“倍数与因数”。(2)原“分数”单元中“分数的意义”这一小节,拆成“分数的意义”和“真分数、假分数”两小节。(3)原“分数的加减法”单元只有一个小节,修改分拆成两小节“分数加减法”和“分数加减混合运算”。(4)原“方程”单元中“方程”小节拆分为两个小节,即“认识方程”和“解方程”。
A revision of textbooks This revision of the original textbook mainly from the adjustment of cell structure, to enhance the relevance of content and exercises, to strengthen mathematical thinking and mathematics activities, to reconstruct the problem solving system and so on. 1. Properly adjust the cell structure. (1) Adjust the contents of common factor and common factor to the first unit “Multiplier and Factor ” in the “Score ” unit “Approx. (2) The meaning of ”fraction“ in the original ”fraction“ unit is broken down into ”fractional meaning“ and ”true fraction, fake fraction“. (3) The original ”addition and subtraction of points“ unit has only one section, and the modification is split into two sections ”fractional addition and subtraction“ and ”fractional addition and subtraction“. (4) The ”“ equation in the original ”equation “ unit is divided into two subsections, that is, ”knowing equation “ and ”solving equation ".
