口算就是不借助计算工具,不用书面表达方式计算过程,依靠记忆,直接通过思维算出结果的一种计算方法。它是笔算的基础,具有用时少、容量大、形式活、速度快的特点,是训练思维敏捷性的良好手段。新《数学课程标准》指出:教师“应重视口算,加强估算,鼓励算法多样化。”那么,在小学数学教学中如何培养学生的口算能力呢?一、以兴趣为先导,让学生喜欢口算1.在游戏中培养兴趣。例如,在低年级计算教学中引入
Mouth calculation is not a calculation tool, without written expression of the calculation process, relying on memory, calculated directly through thinking a result of the calculation method. It is the basis of pen calculations, with less time, large capacity, form and speed, is a good means of training thinking agility. The new “Mathematics Curriculum Standard” pointed out: Teachers “should pay attention to port count, strengthen the estimation, to encourage the diversity of algorithms. ” So, how to train students in the primary mathematics teaching portability? First, interest as a guide to make students like Mouth count 1. In the game to develop interest. For example, introduced in lower grade computing teaching
