The difference between orange edition and green edition of "new explanation and new teaching material"

The difference between the orange version and the green version of the new textbook is the grade level.

"Using the original text as a topic is not only convenient for students to remember and recite, but more importantly, it retains the original flavor of traditional culture." Lu Tianlong, director of Beijing Education Society and vice president of Beijing Sustainable Development Education Society, is the head of the textbook editorial board. Considering the age characteristics, knowledge level and aesthetic level of students, this set of teaching materials is mainly used by third-grade primary school students, and the course is completed within one year. This set of textbooks has been used in Shi Jia Primary School, Fu Xue Primary School, Anwai Santiao Primary School, Heizhima Primary School, Captain Primary School, Special Education School, Shuguang Primary School, Jingshan Primary School, Dongsiqitiao Primary School, Fang Jia Hutong Primary School, Suianbo Primary School, Huiwen Primary School, Zhongshili Primary School, Chongwen Huimin Primary School, Li Baohua Primary School, Qianmen Primary School, Jintai Primary School, Tiantan Li Nan Primary School and Tiantan Dongli Primary School.
