教学内容:乘法的初步认识(六年制小学数学课本第二册第73页—74页)。教学要求:使学生初步了解乘法的意义,知道求几个相同加数的和用乘法计算比较简便。认识乘号,会读、写乘法算式。教学重点:初步建立乘法的概念。教学难点:把相同加数连加的算式改写成乘法算式。教学过程: 一、复习: 1.出示教材第73页熊猫图放大图。教师提问:谁能说说这幅图的意思?再提出一个问题,并解答出来(指名一学生到黑板前板演)。 2.出示教材第73页的梨放大图: 教师提问:这幅图画的是小朋友们爱吃的鸭梨。请小朋友根据图的意思列出一道求和的算式(指名一学生到黑板前板演)。 [设计意图:通过生动、形象的直观图,唤起
Teaching Content: Preliminary Understanding of Multiplication (Six-Year Primary School Mathematics Textbook, Second Volume, pp. 73-74). Teaching Requirements: To enable students to initially understand the significance of multiplication, know that seeking a few same sums and multiplication is relatively simple. Know multiplication, read, write multiplication formula. Teaching focus: The initial establishment of the concept of multiplication. Teaching Difficulties: The same plus the arithmetic plus rewrite the multiplication formula. Teaching process: First, the review: 1. Present the p. 73 panda picture to enlarge. Teacher Question: Who can tell the meaning of this picture? Ask another question and answer it. (Name a student to the blackboard front panel). 2. Present the pear on page 73 Zoom out: Teacher Question: This picture shows the pear that children love. Please children according to the meaning of the map out a summation formula (named a student to the front panel play blackboard). [Design intent: a vivid, visual image of the image, evoking
