表内乘法和相应的除法在低年级数学课本中占的比重很大。它是以后学习多位数乘除法的基础,起着计算工具的作用。它的容量大,包括表内乘法和相应除法的口算,乘除法的初步意义和互相联系,简单乘除应用题等;它的教学要求高,乘法口诀和运用口诀求商必须十分熟练,简单乘除法应用题要在这一阶段打好基础。所以,教完这些内容以后,应着重在以下方面组织综合训练。 一、促进口诀熟练的训练。 2至9的乘法口诀应进行全面复习。2、3、4的乘法口诀掌握不难,5和9的乘法口诀容易记忆和熟
Table multiplication and the corresponding division in the lower grades of math textbooks account for a large proportion. It is the basis for learning multi-digit multiplication and division later, playing a role as a calculation tool. Its large capacity, including the table multiplication and the corresponding division of the mouth count, multiplication and division of the primary significance and interrelated, simple multiplication and division of application problems; its high teaching requirements, multiplication formulas and the use of formulas must be very skilled, simple multiplication and division Application questions to lay a good foundation at this stage. Therefore, after teaching these contents, we should focus on the following aspects of organizing comprehensive training. First, to promote skilled training. Multiplication formulas 2 to 9 should be reviewed comprehensively. The multiplication formulas 2, 3, and 4 are easy to master. The multiplication formulas 5 and 9 are easy to remember and mature
