【Abstract】Primary school students often directly affect teaching efficiency due to insufficient concentration and poor understanding in mathematics teaching activities. In this regard, teachers should pay attention to, strengthen research, and use new curriculum reform concepts and new technical methods as supplements to allow vivid, short and effective micro-class resources into the primary school math classroom. Driven by the cultivation of students core literacy, it guides students to develop a strong interest in learning, activate urgent cognitive desires, and effectively enhance teaching efficiency, driven by micro-class resources, to ensure better progress and implementation of primary school mathematics classroom teaching, and encourage students Mathematics core literacy is better cultivated and practiced to pave the way. This article gives the application strategy.

一、小学数学核心素养的构架及要求分析
经过对全新《小学数学课程标准》进行分析可以发现,小学阶段学生应该具备的数学核心素养主要包括六个方面,其中各要素之间相互融合、彼此渗透、有机衔接,是小学数学教学中必须贯彻和落实的要求和准则。
其主要构架及要求,具有如下特点:一是数学抽象素养,其主要指学生通过数学学习,将事物的物理属性进行拓展和延伸,对数量、图形之间的关系进行抽象、归纳、整合,进而总结出具体规律并用诸多数学符号予以反馈的基本素养。其实小学生数学抽象意识的基本构架,对理性思维的塑造有着重要影响。二是逻辑推理素养,主要指从现有命题、已知条件、具体事物出发,按照固有规则或者定理,推导某个命题的真伪。其涉及的数学思想主要包括类比、归纳、演绎等,对学生数学思维能力的形成有着重要作用。……
