基于核心素养的小学数学“说理”课堂初探——以“需要多少钱”教学为例

Elementary School Mathematics “reasoning” Classroom Based on Core Quality——Take “How much money is needed” teaching as an example

在小学数学课堂教学中,教师可营造和谐、平等的"说理"环境,留给学生更多的思考空间和讲理时间,使其在说理中养成言之有理、落笔有据的思维习惯,让学生从逐步"学会"到自己"会学",进而达到对知识的深层次认知,真正理解数学本质,为培养学生的核心素养打下坚实的基础。本文以"需要多少钱"教学为例,从明理、讲理、辨理三个层次进行阐述。

In the classroom teaching of elementary school mathematics,teachers can create a harmonious and equal "reasoning" environment,leaving students more thinking space and reasoning time,so that they can develop rational and well-founded thinking in reasoning Habits allow students to gradually "learn" to "learn" by themselves,and then achieve a deep understanding of knowledge,truly understand the nature of mathematics,and lay a solid foundation for cultivating students’ core qualities. This article takes the teaching of "how much money is needed" as an example,and elaborates it from three levels:reasoning,reasoning,and reasoning.
