Which textbook is good for all-in-one colorful classes in primary schools?

Colorful class is good. Multi-in-one colorful classroom is based on the national curriculum standards for primary and secondary schools, combined with the latest teaching concepts and methods, covering the curriculum resource database of primary schools from grade one to grade six. Including mathematics, Chinese, English and other subjects, covering all grades and stages of knowledge and skills, but also provide online lectures, homework correction, curriculum evaluation and a series of auxiliary teaching functions. While paying too much attention to the exam will neglect the cultivation of other aspects, such as thinking ability and innovation ability, and it will lack personality and cost more.
