国标本苏教版数学教材第五册68~69页安排了一课数学实践活动。教材设计了不同形式的活动,帮助学生巩固对长方形和正方形的特征、周长的含义以及简单平面图形周长计算方法的认识,进一步发展数学思维,提高与他人合作交流的能力。《数学课程标准》明确了“图形与几何”的教学应积累活动经验。数学活动经验需要在“做”的过程和“思考”的过程中积淀,在活动过程中逐步积累。结合学习内容,设计有效的数学探究活动,使学生经历数学的发生发展过
The national specimen Sujiao version of the fifth edition of mathematics textbooks 68 ~ 69 pages arranged a lesson in mathematical practice. The textbook has been designed with various activities to help students consolidate their understanding of the features of rectangles and squares, the meaning of circumference, and the calculation of simple plan-graphic perimeters, further develop mathematical thinking and enhance their ability to work with others. “Mathematics curriculum standards” made it clear that the teaching of “graphics and geometry” should accumulate experience of activities. The experience of mathematical activities needs to be accumulated in the process of “doing” and “thinking” and gradually accumulating in the process of activities. Combine the learning content, design effective mathematics inquiry activity, enable the student to experience the occurrence and development of mathematics
