我区永安小学余秉谦老师上了一堂“平面组合图形面积计算”的复习课,教学效果较好,现将课堂教学实况摘要如下。一、复习提问: 1.复习所学过的平面几何图形的面积公式(要求先用文字叙述,然后用字母写出计算公式)。 2.用幻灯依次映出图形,求图形的面积(要求学生口叙算式,并计算出得数)。 Yu Yongqian Primary School, our district teachers on a “plane combination of graphic area calculation” review class, teaching is better, the classroom teaching is now summarized as follows. First, the review questions: 1. Review of the area geometry of the plane formula (requires first described in words, and then use the letter to write out the formula). 2. With slideshow in turn reflect the graphics, graphics area (requires students to recount the formula, and calculate the number).
