计算能力是数学学习的一项重要能力,而这项能力培养的最佳阶段便是小学阶段。在小学阶段的数学教学中,计算教学占据着很大比例。计算能力强是学好数学的根本保证。学生具有良好的计算能力,他处理和解决实际问题的能力就会很强,对数学运算及测量方面都会有很强的认识。如果学生没有扎实的计算能力,不仅会影响学生的学习效率,还会严重阻碍学生思维的发散性、跳跃性和灵活性,不利于学生创造能力的发展。我 Computational ability is an important ability in mathematics learning, and the best stage of this ability training is primary school. In elementary school mathematics teaching, computing teaching occupy a large proportion. Computational ability is a fundamental guarantee for learning mathematics. Students have a good computing power, his ability to deal with and solve practical problems will be strong, there will be a strong understanding of mathematical operations and measurement. If students do not have a solid computing power, it will not only affect the learning efficiency of students, but also seriously hamper the divergence, jumping and flexibility of students ’thinking, which is not conducive to the development of students’ creative ability.
