北师版五年数学下册内容包括分数乘法﹑长方体﹑分数除法和分数混合运算﹑百分数﹑统计等六大板块。在教学本册内容的时候,结合学生的实际情况,遇到若干问题在平时教学时做了积累,感触颇深:数学课堂,让学生的手和脑动起来,让课堂活起来,使学生真正成为课堂的主人。一、动手做数学小实验测量石块的体积,是学生在已经学会长方体和正方体体积计算的基础上进行的实验,主要是针对一些不规则的面的练习马上就知道要少加
The five-year undergraduates’ mathematics book consists of fractional multiplication, cuboid, fractional division, mixed fractional operation, percentage and statistics. In the teaching content of this book, combined with the actual situation of students, encountered a number of problems encountered in the usual teaching accumulated, deep feelings: Math class, so that students’ hands and minds up, so that the classroom to live together, so that students really Become the owner of class. A hands-on experiment to measure the volume of small stones in mathematics, students have learned to cube and cube volume calculations based on the experiment, mainly for some irregular face exercises immediately know to add less
