一、主要内容本单元的教学内容主要有:乘法的初步认识和2~6的乘法口诀两部分组成。其中,乘法的初步认识安排有3个例题,知识点有乘法意义的初步理解、乘法算式各部分的名称和意义、会根据图意列出乘法算式;2~6的乘法口诀部分安排有7个例题,包括口诀的编写、意义的理解以及记忆和应用。二、简要分析求几个相同加数的和,可以用乘法计算比较简便,简单地说就是“求几个几的和是多少,用乘法。”对这一意义的理解将对今后的教学起着至关重要的作用。当我们学习“几倍”时,实际是转化成“几个几”来理解的,3的5倍,就是5个3,在整数范围内,“几倍”与
First, the main content of the unit’s teaching content are: the initial understanding of multiplication and 2 to 6 multiplication formula consists of two parts. Among them, the initial understanding of multiplication arrangements have three examples, the knowledge point has the initial understanding of the meaning of multiplication, the name and meaning of each part of the multiplication formula, according to the diagram shows the multiplication formula; 2 to 6 part of the multiplication formula arranged seven Example, including the formulation of formulas, the understanding of meaning and memory and application. Second, a brief analysis of seeking the same number of sums and can be calculated by multiplication is relatively simple, simply say “how many and what is the sum of multiplication.” Understanding of this meaning will be the future Teaching plays a crucial role. When we study “a few times ”, the actual is translated into “a few more ” to understand, 3 times 5 times, that is 5 3, in the range of integers, “several times ” and
