记得那是在淮北市举行的全国性的观摩课,执教老师都是享誉全国的名师。有一位女教师在教学三年级数学《统计》这一课时,播放了一段视频:在一段繁忙的马路上,各种车辆来往穿梭着。老师让学生统计视频中小汽车、摩托车、卡车、拖拉机各有多少辆。看到这,我不禁心中赞叹:老师的设计独具匠心,用这样一个生活中的实例让数学教学联系实际,学生一下子就来了兴趣。不仅如此,教师在这儿还埋下了一个特别棒的伏笔——因为视频中的车辆来往如织,而且没有任何规律性,就是我们坐在台下的这些老 I remember that is held in Huaibei City, a national observation class, coaching teachers are renowned national teacher. A female teacher played a video while teaching Math Statistics, third grade: a wide variety of vehicles traveling across a busy road. The teacher asked students to count the number of cars, motorcycles, trucks and tractors in the video. Seeing this, I can not help but praise my heart: the design of the teacher originality, with such an example of life so that the teaching of mathematics in contact with reality, students suddenly came to interest. Not only that, the teachers also laid a very great foreshadowing here - because the vehicles in the videos are moving and have no regularity, that is, the old
