口算是一种只凭思维和语言活动不借助任何工具的计算方法。《全日制义务教育课程标准》指出:“培养学生口算、估算、速算的意识,对发展学生的计算能力,让学生拥有良好的数感,具有重要的作用。”口算是一切计算的基础,没有好的口算能力,提高计算能力犹如空中楼阁,可望而不可及。如何提高孩子的口算能力呢?下面笔者结合自己的教学实践,谈一些看法。一、明白算理,掌握算法数学家王元有句名言:“数学学习的诀窍在于
Mouth counting is a method of calculation that uses nothing but thought and language activity alone. The full-time compulsory education curriculum standard states: ”The cultivation of students ’awareness of oral calculation, estimation and speed calculation plays an important role in developing the students’ computing abilities and in enabling students to have a good sense of number.“ ”Calculation is the basis of all calculations , There is no good calculus ability to improve computing power like the palaces in the air, out of reach. How to improve the child’s ability to account? Here I combine my own teaching practice, talk about some ideas. First, understand the arithmetic, master algorithm Mathematician Wang Yuan has a famous saying: "The trick is to learn mathematics
