The Study Of Teaching Case In The Field Of Comprehensive And Practice In Primary Mathematics

"Integrated with practice " is a new field in primary school mathematics,after the new curriculum reform the field becomes more and more important.The class of mathematics integrated with practice in primary school is characterized by openness,practicality and comprehensiveness,higher requirements have been put forward for teaching.Many teachers do not have a clear understanding of the "integrated with practice"class,and lack proper teaching designs.In view of this,this paper will make a detailed study of the teaching cases of comprehensive and practical mathematics in primary school.This article adopts the methods of literature,observation,interview and comparison,From literature review,educational value,theoretical basis of related research,teaching content analysis and teaching design principles of "integrated with practice ",this paper does a systematic research on the class of integrated with practice,and analysis specific cases to reduction true and effective classes.Four cases selected in this article are very representative,they are hands-on type,investigation interview type,subject research type and game based type,cross low and high section,have done a typical research on the integrated with practice class of different age groups and different classes.It provides a reference for primary school teachers in the field.
