Students with weak foundation: you can thoroughly understand the textbook knowledge points of "Complete Solution of Primary School Textbooks" and lay a good foundation. In addition, you can match some oral exercises.

Students with moderate grades: "53 Days of Practice" and "Huanggang Little Champion Exercise Book", choose one set as a supplementary exercise, mainly to consolidate the knowledge points in the class, and there will be one or two sets of exercises on the basis of the class.

Top-notch students: You can use "draw inferences from others" and "competition mathematics textbook+guidance" for thinking development training.
