口算需要学生能迅速地、合理地、高效地对计算做出反应,口算方法的灵活性和创造性能有效地锻炼学生的反应能力、学习能力、观察能力、记忆能力、创新能力和总结能力。为进一步强化小学生的口算能力,培养学生的竞争意识,教师应该在加强小学数学基础教育的同时注重加强小学生的口算训练,从而促进学生的全面发展。 Students need to be able to react quickly and reasonably efficiently to the calculations. The flexibility and creativity of the oral calculation method can effectively stimulate students’ ability to respond, learn, observe, remember, innovate and summarize. In order to further strengthen the ability of primary school students in numeracy and foster students ’sense of competition, teachers should pay more attention to primary school students’ oral arithmetic training while strengthening basic mathematics education in primary schools so as to promote the all-round development of students.
