一、教学内容:第九册第一单元第1课时。 二、教学目的:使学生理解小数乘以整数的意义;掌握法则,并能运用法则,正确进行计算。 三、教学重点:掌握小数乘以整数的计算法则。 四、教学难点:理解算理。 五、教学过程: 1.复习: 0.56扩大( )倍是5.6。 0.082扩大( )倍是82。 86.4缩小( )倍是0.864。 把34.05扩大100倍是( ),再缩小100倍是( )。 First, the teaching content: the ninth unit first unit when the first lesson. Second, the purpose of teaching: to enable students to understand the meaning of decimal multiplied by integers; grasp the law, and can use the law, the correct calculation. Third, the teaching focus: master the decimal multiplication by the law of the integer. Fourth, difficult teaching: understanding of arithmetic. Fifth, the teaching process: 1. Review: 0.56 to expand () times is 5.6. The 0.082 expansion () times is 82. 86.4 Reduced () times is 0.864. To enlarge 34.05 100 times (), and then reduce 100 times ().
