小学数学知识中的计算部分,在小学数学知识结构中占很重要的地位。计算能力是学习数学和其他学科的重要基础,在小学数学教材中,计算教学所占的比重很大,学生计算能力的高低直接影响着学生学习的质量。《义务教育数学课程标准》中明确指出:“应该把培养学生的计算能力作为小学数学教学的一项重要任务。”因此,如何提高学生的计算能力就成了小学数学教学研究的重要问题。中高年级中有许多的计算内容:小数的乘法、小数的除法、解
The calculation part of elementary mathematics knowledge occupies a very important position in elementary mathematics knowledge structure. Computational ability is an important foundation for learning mathematics and other subjects. Computational teaching occupies a large proportion in elementary mathematics textbooks. The ability of students in computing directly affects the quality of students’ learning. “Compulsory education mathematics curriculum standards” clearly states: “should be to develop students ’computing power as an important task in primary mathematics teaching.” Therefore, how to improve students’ computing power has become an important issue in primary school mathematics teaching and research . There are many calculations in the upper and middle grades: multiplication of decimals, division of decimals, solutions
