相等物体体积的转换是小学数学教学的难点内容。某一天的课间 ,学生在课桌上起劲地用相同体积的橡皮泥捏出不同形状的物体模样 ,此时我茅塞顿开 :“让学生运用相同体积的橡皮泥做出不同形状物体模样 ,来直观沟通学生的形象思维 ;采用比较、议论、猜测、验证等方法 ,来促进学生 The conversion of the volume of equal objects is the difficult content of elementary mathematics teaching. On the day of class, students vigorously use the same volume of plasticine to pinch objects of different shapes on the desks. At this moment, I put it aside: "Let students use the same volume of plasticine to make objects of different shapes to visualize Communicate the image of students thinking; using comparison, discussion, speculation, verification and other methods to promote students
