义务教育阶段的数学课程,出发点是促进学生全面、持续、和谐发展,其目的是为学生的可持续发展奠定良好的基础。那么,怎样才能让数学课程促进学生全面、持续、和谐的发展呢?在这里,我主要想谈一谈口算在数学教学中的可持续发展。小学数学知识,至少90%以上是计算。而计算在很大程度上就是口算,不管多么复杂的计算,包括解决实际问题,最终都是归 The starting point of mathematics curriculum in compulsory education stage is to promote the students’ comprehensive, sustained and harmonious development with the purpose of laying a good foundation for the sustainable development of students. So, how to make mathematics courses to promote the development of students in a comprehensive, sustained and harmonious manner? Here, I mainly want to talk about the math teaching in the sustainable development. Elementary mathematics, at least 90% is calculated. The calculation is largely a matter of the word, no matter how complex calculations, including solving practical problems, are ultimately attributable
