计算是小学数学学习中最基础的部分,学生的计算能力直接影响着其今后数学的学习情况。我国在20世纪后提出了三大数学能力,即运算能力、空间想象能力、思维能力。通过将运算能力放在最前面,我们可以看出其在数学学习当中的重要地位与作用。因此,在小学数学教学中,教师要格外注重培养学生的运算能力,为今后数学课程打下坚实基础。我国小学生的运算能力包括口算、笔算、估算。对于简单的计算题可以让学生直接进行口算,即心算进行解决,培养学生敏捷准 Computation is the most basic part of primary school mathematics learning. The computing power of students directly affects the learning of mathematics in the future. After the 20th century, our country put forward three major mathematical abilities, namely computing power, space imagination ability and thinking ability. By putting computing power first, we can see its importance and role in maths learning. Therefore, in primary mathematics teaching, teachers should pay special attention to cultivating students’ computing abilities and lay a solid foundation for the future mathematics curriculum. The computing power of primary school pupils in our country includes mouth counting, pen calculation and estimation. For a simple calculation questions can allow students to conduct oral calculations, that is, mental arithmetic to solve, develop students agile quasi
