前几天,有幸学习了来自宜兴天问小学的王昌胜老师执教的《角的度量》一课,真正领略了王老师对《图形与几何》领域的教材以及新课标理念的深度解读和准确把握,可谓收获良多。现采撷几个片断与大家分享。【片断一】师:怎么测量这个角的大小?生:量角器。师:古时候,人们没有量角器怎么量呢?(学生在苦思冥想中,个个欲罢不能)师:量一条线段有多长怎么量?测量一个较大正方形的面积怎么量?

(Students think hard, each unable to stop) Teacher: how to measure how long a line segment? How to measure the area of a larger square?
