《小学数学教学大纲》中明确指出:“小学数学教学的一项重要任务是培养计算能力……应该要求学生算得正确、迅速,同时还应注意计算方法合理、灵活。”我认为加强低年级的口算训练,是提高学生计算能力的关键。下面谈一谈我在教学中的具体做法。一、准确理解教材,有计划地进行口算训练小学数学教材系统性、科学性很强。前后知识的内在联系非常紧密,各种口算内容的安排由浅入深,互相连贯。教师在备课时要注意挖掘知识间的 “Elementary Mathematics Teaching Syllabus” made it clear: “An important task in primary mathematics teaching is to develop computational skills ... Students should be asked to be correct and prompt, but also pay attention to the calculation method is reasonable and flexible.” I think to strengthen the lower grades Mouth arithmetic training, is to improve the calculation of the key students. Here to talk about my specific practice in teaching. First, an accurate understanding of teaching materials, a planned exercise of primary school mathematics textbook teaching systematic, highly scientific. Before and after the knowledge of the inner relationship is very close, all kinds of mouthful of the content arrangement from top to bottom, coherent. Teachers should pay attention to digging knowledge during lesson preparation
