“等可能性”是苏科版版《数学》九年级上册的内容。本节课是学生在知道事件发生的可能性有大小,能对一些简单事件发生的可能性作出定性描述的基础上,通过游戏活动体验只有“等可能性事件”的游戏规则才是公平的,并在此基础上设计简单的、公平的游戏规则。游戏应该怎么设计,才能使学生深度参与探究活动,真正引发学生数学思考呢?我在执教这节课时,做出了大胆、有益的尝试。
“Possibility of other ” is the Su Ke version of “Mathematics” ninth grade on the content. This lesson is based on the students the possibility of knowing the size of the event, the probability of some simple events can be based on the qualitative description of the game through the experience of activities such as “and other possible events, ” the rules of the game is fair And based on this, design simple and fair rules of the game. The game should be how to design, in order to enable students to participate in deep exploration activities, the real cause of students in mathematical thinking? I taught this lesson, made a bold, useful attempt.
