Personally, I think that in the middle of the semester, I can first test each unit I have learned, and whether the knowledge points are solid. . I recommend you two exercise books. The first is the complete solution of primary school mathematics textbooks. On the last page of the complete solution of the textbook, they published a matching workbook, the size of A4 paper. There are pictures on the cover. . Or the cover of "Standard Classroom Practice and Examination" is jubilant series (Beijing Normal University Edition), and the publishing house is Jilin University Press. Personally, I think this standard classroom is more suitable for students with flexible thinking. By the end of the term, I will buy a language version and an English version of The Final Sprint. .

I hope I can help you. The above information has achieved good results in our remedial classes. .
