教学思考:“看图找关系”是北师大版教材六年级上册第83~84页“数学好玩”单元中的一个专题活动。教学时,我着重围绕以下问题展开了思考、设计和践行。1.核心知识是什么?体验分段函数是本节课的核心。当然,我们并不需要让学生知道分段函数,只是一种体验,让学生对函数有一种经历,为分段函数的学习积累数学活动经验。其落脚点是会“看图找关系”。看图
Teaching thinking: “Look at the map to find the relationship ” is a special activity in the sixth grade of the Beijing Normal University edition of the sixth grade on the first 83 ~ 84 pages “math fun ” unit. Teaching, I focused on the following questions started thinking, design and practice. 1. What is the core knowledge? Experience the segmentation function is the core of this lesson. Of course, we do not need to let students know the segmentation function, just an experience, so that students have an experience of the function, accumulating mathematical activity experience for the learning of piecewise functions. Its foothold will be “look at the map to find the relationship.” Look at the picture
