《数学课程标准》按“一贯”思想将中小学的数学教学分为三个学段,这一方面为我们指出教学是有阶段性的,应该尊重儿童发展的生理和心理特征;另一方面更明确地揭示了中小学数学教学的连贯性,说明这三个学段的教学是不可割裂的。作为一名小学数学教师,必须树立“大课程观”的思想,在教学中尽可能地创造条件,作好衔接上的铺垫,着眼学生的发展。一、扬教材之优点1.活化教材促衔接北师大版数学教材为了体现义务 According to the “standard of mathematics curriculum”, the teaching of mathematics in primary and middle schools is divided into three periods according to the idea of ​​“consistent”. On the one hand, we point out that teaching is phased and should respect the physical and psychological characteristics of children’s development; on the other hand, In this respect, the coherence of mathematics teaching in primary and middle schools is revealed more clearly, which shows that the teaching of the three academic periods can not be separated. As a primary school mathematics teacher, we must establish the idea of ​​“big curriculum concept”, create the conditions in the teaching as much as possible, pave the way for convergence, and focus on the development of students. First, the advantages of Yang textbook 1 activation textbook to promote convergence of the Beijing Normal University version of mathematics textbooks in order to reflect the obligations
