A good oral calculation is the basis of correct calculation, a necessary condition to improve teaching effect and a good way to develop students' intelligence. Schools and parents should attach importance to students' education in this respect, rather than just writing compositions and doing problems. The following is the relevant information of "A Complete Book of Oral Calculations for Primary School Students in Grade One", hoping to help you.
