【教学内容】北师大版数学六年级下册第86页。【教学过程】一、问题导航,揭示课题1.想办法使下面两个式子成立。6()=6000()8()>8()>8()。在学生独立思考的基础上解决这两个问题。2.引出课题。在学生回答的基础上引出课题《常见的量》,对小学阶段的计量单位进行系统的整理和复习。【设计意图:让学生在解决“把不相等变为相等,把相等变为不相等”的问题情境中发现可以使用计量单位,感受计量单位的重要性,从而自然进行《常见的量》的整理与复习。】
【Teaching content】 Beijing Normal University version of mathematics sixth grade volume 86th page. Teaching process A problem navigation, revealing the subject 1. Find ways to make the following two formulas established. 6 () = 6000 () 8 ()> 8 ()> 8 (). Solve these two problems on the basis of students’ independent thinking. 2 lead the subject. On the basis of the students’ answers, it leads to the topic “Common Quantity”, systematically arranging and reviewing the units of measurement in primary school. [Design intent: to allow students to find out the importance of using units of measurement and measuring units of measurement in solving problem situations such as “changing unequal into equal and equal to unequal” The finishing and review. 】
