根据学生熟悉的生活情境“开心购物”为主线贯穿课堂，巩固复习了学生对人民币和音符的认识，将所学知识点与故事情节相串联，让学生体验了数学学习的乐趣。通过模拟购物活动，让学生通过付钱和找钱的过程，把人民币的运用与音符的计算相结合，感受了学科知识的融合,加强了思维多样化的体验。

The theme“Happy shopping”based on students’s familiar life setting ran though the class, consolidated and reviewed students’s knowledge of RMB and musical notes. Students had fun in math studying connecting the knowledge learned to the storyline. Students sensed the integration of the subject knowledge and had their experience of diverse thinking through the process of payment, and combining musical notes with calculation in the simulated shopping activity.

人民币与“音符币”相结合，增强了学科之间的关联性，在人民币计算的基础上，同步运用“音符币”，锻炼了学生数学发散思维和推理能力。

The combination of RMB and “Musical note currency”strengthened the relation between subjects. Using the “musical note currency”on the basis of RMB calculation enabled students to develop their mathematical divergent thinking and inferential capability.

购物的过程中，学生自主购物说出自己想买的物品，不仅可以锻炼学生语言表达能力，还可以增强数学知识的理解与输出。分组活动进行挑战，在运用数学知识的同时，进一步感受了数学学习生活化，锻炼了学生的数学思维能力，增强了团队合作意识。

In the shopping process, students shopped independently and named the items they wanted, which not only allowed students to practice their language expression ability, but also enhanced their understanding and outputting of mathematical knowledge.The group challenge activities also made students experience the life-oriented approach of learning mathematics, developed student’s mathematical thinking ability,and enhanced their awareness of collaboration.
