一、说教材《小小商店》是苏教版义务教育课程标准一年级下册第七单元的一节实践活动课。课程标准把数学内容分为四大领域:数与代数,图形与几何,统计与概率,综合与实践。《小小商店》属于第四领域——综合与实践。小小商店这课是以学生的购物经验和已经学习的关于加、减法计算和人民币的有关知识为基础,学生进行模拟购物,经历购物过程,积累丰富的经验,探索解决问题的策略。学好这部分知识,不仅可以提高学生的人民币换算和100以内加减法运算的能力,同时为以后进一步学习加减法计算和高品质地生活打下坚实的基础。
First, the textbook “little shop” is a section of practical activities of the seventh unit of the first grade of the compulsory education curriculum standard of the Sujiao version. The curriculum standard divides mathematics into four main areas: number and algebra, graph and geometry, statistics and probability, synthesis and practice. “Small shops” belong to the fourth area - synthesis and practice. This small shop is based on the students’ shopping experiences and the relevant knowledge about addition and subtraction calculation and RMB that students have learned. Students conduct shopping simulation, shopping experience, and accumulated rich experience to explore strategies for solving problems. Learning this part of knowledge can not only improve students’ ability of RMB conversion and addition and subtraction operations within 100, but also lay a solid foundation for further study on addition and subtraction calculation and high-quality living.
