数列求和运算同学们并不陌生,在小学五年级时学生就已经开始有所涉及,并且随着时间的推移数列问题变得越来越系统化,到高中的时候学生会专门学习等差数列和等比数列的相关运算.基于数学知识的内在连续性,教师希望同学们能够在小学、初中的时候就打下一定的数列运算基础,这样不仅利于同学们对数学问题的整体性把握,同时也会帮助同学们不断提升对同一个数学问题的认识,在苏教版 The summation of sequence operators is no stranger to students, and students have begun to be involved in the fifth grade of primary school, and as time goes by, the issue of sequence becomes more and more systematical. By the time of high school students will devote themselves to arithmetic progression, Based on the inherent continuity of mathematical knowledge, teachers hope that students can lay a certain number of basic computing operations in elementary and junior high schools, which not only helps students to grasp the integrity of mathematical problems, but also Help students to continuously raise awareness of the same mathematical problem in the Sujiao version
