一、内容的增删和变化1.重新整合简易方程的教学内容。小学生对方程的认识主要包括方程的含义、解简易方程和列方程解决一些实际问题。通过这部分内容的教学,一方面可以使学生更加透彻地理解实际问题中的数量关系,提高应用数学方法解决实际问题的能力;另一方面也能使学生初步感受方程的思想,从而为后续学习打好基础。与修订前的教材相比,这部分内容的容量有了较大幅度的增加:原五年级下册只要求学生解一步计算的方程,并列一步计算的
First, the content additions and deletions and changes 1. Re-integration of simple equation teaching content. Primary school students' understanding of the equation mainly includes the meaning of the equation, solving simple equations and column equations to solve some practical problems. Through this part of the content of teaching, on the one hand can make students more thorough understanding of the quantitative relationship between the actual problems, improve the ability of applied mathematics to solve practical problems; the other hand, students can also make the initial impression of the equation, so as to follow-up study Lay the foundation. Compared with the pre-revision textbook, this part of the content has a more substantial increase in capacity: the original fifth grade only requires students to solve one-step calculation of the equation, and calculated in parallel
