《数学课程标准》明确指出:“应重视口算,加强估算,鼓励算法多样化。”在数学教学中,引导学生积极开展“算法多样化”的活动,积极鼓励不同学生采取不同的解决问题的策略,为学生提供数学交流的机会,有利于促进学生的数学思维活动,提高数学思维能力。由于提倡算法多样化只是在数学教学改革中刚刚进行教学尝
The Mathematics Curriculum Standard clearly states: “Attention should be paid to port counting, estimation should be strengthened, and algorithms should be encouraged to diversify.” In mathematics teaching, students are encouraged to actively carry out “algorithm diversification” activities and actively encourage different students to adopt different tactics to solve the problems , To provide students with the opportunity to exchange mathematics, is conducive to promoting students’ mathematical thinking activities, improve mathematical thinking ability. Due to the diversification of algorithms, it is only teaching in mathematics teaching reform
