本文以两位教师执教“位置”(人教版小学数学一年级下册第一单元)一课时所设计的“找座位”为例,就如何构建富有生机活力的数学课堂谈一些思考体会。案例A:教师给学生每人发一张座位表,让学生根据手中的座位表提示重新一一对号入座,并通过“你为什么坐在这?”、“他坐对了吗?”等问题,启发学生思考、 In this paper, two teachers coached the “position” (PEP mathematics first grade first volume of the first unit) designed a class “find a seat” as an example, how to build a dynamic mathematical class to talk about some Think and feel. Case A: The teacher sends each student a seat table so that the student can re-seat the seat according to the seat table in his hand and pass “Why do you sit here?”, “Is he sitting right?” And other issues, inspire students to think,
