In order to implement the working spirit of the Ministry of Education to promote the "double reduction" work, further summarize and promote the school teaching reform, ensure the deep learning under the background of "double reduction", reduce the students' schoolwork burden, improve the teaching efficiency and improve the teaching quality.This semester, we gradually carry out the "Chinese and Western culture" integration subject project learning activities.In the 21st century with the rapid development of China's economy and cultural influence, and international exchanges and cooperation between western countries is increasingly frequent and extensive, in the based on learning Chinese culture at the same time, let students explore and understand the differences between Chinese and western culture, expand students' international vision, cultivate patriotism, form a healthy outlook on life, lay a good foundation for their lifelong learning and development.

With the theme of "Money Grand View Garden", mathematics discipline can not only arouse students' interest, but also enrich their knowledge and broaden their horizon, which is very meaningful.The currencies of all countries in the world are ordinary and mysterious, and the use of money has a long and complex history, and the forms of its existence are also different according to different times and cultural backgrounds. The currencies of all countries in the world contain different beliefs, ideas, thoughts and cultures, as well as different printing and production technologies.This activity fully arouses students' curiosity and thirst for knowledge, and studies the cultural background, historical origin and currency exchange rate of coins in different countries. It is of great significance to train students to take root in China, integrate China and abroad, focus on the world and become elite talents to explore the world.

The third and fourth grade showed students' learning content in the form of hand-copied newspaper. With the theme of "World Supermarket", students began to actively collect currency pictures from various countries a week in advance, showing great interest.

Most of the students are through the Internet to collect the currency pictures, some parents work in the bank, copy the RMB currency, the picture is very clear; some students to the uncle abroad, take the real currency, and then color printing; some students collect the collection of commemorative money copy, is really a family mobilization!

The second week was the production of the Handcopy newspaper.In the production process, the students concentrate, rich imagination, design a unique layout, comprehensive use of the knowledge learned, in order to solve the practical problems encountered in the production process.

All kinds of hand copy newspaper production finished, the students in the class made wonderful production experience sharing, to share their own to collect money channels and the collection process of fun, share the ideas of their design hand copy newspaper, share their own story under the background of national currency history, share their currency transactions to this country.This comprehensive practice activity has opened students 'horizons, enriched students' understanding of Chinese and Western culture, and enhanced students' interest in learning.

Through the study of the currencies of the world, the students not only understood the currencies of the various countries, but also knew the significance of the existence of currencies and the history of development, understood the cultural knowledge of the coins, and presented them with exquisite patterns.In this activity, the students not only enriched the knowledge, harvest happiness, more importantly, felt the value and charm of mathematics discipline, for them to learn mathematics to set up confidence, laid an ideological foundation.

"World Bank" simulation activities in grade 5 and 6.Paper currency is a medium commonly used in the circulation of commodities. It is a necessary skill for contemporary primary school students to be familiar with the world currency that plays an important role in the international circulation of commodities.Commonly used world currencies are: US dollar, euro, British pound, Japanese yen, RMB and so on.

Before the activity begins, the teacher prepared RMB sample and calculator in advance.As "small tellers" of virtual banks, some students check the exchange rate of world currency to RMB in advance, make "exchange rate posters" with corresponding national elements, and prepare the common service language of bank tellers; some students print foreign currency of certain face value and collect the corresponding background knowledge.

During the activity, the students will first introduce the background knowledge of the corresponding currency, and then go to the virtual bank to find a "small teller" for currency exchange.

Through the bilingual dialogue, students deepened their understanding of the "exchange rate" in the exchange process, felt the difference in currency value and purchasing power of different national currencies, and initially felt that the "exchange rate" was influenced by international political, economic, cultural and other factors.Through this activity, the students' perceptual understanding of money was enhanced, and their financial awareness and the value concept of using money were initially established.

Qiyuan School has always adhered to the teaching and scientific research of mathematics, and has been striving to practice the road of improving quality and efficiency. It focuses on the development of "five education" to improve students' "five-yuan quality", and carries out practical, open and experiential sub-subject integration teaching.In the teaching reform, implement the concept of conveniently oriented education and cultivate students' innovation ability.The theme activity of "currency Grand View Garden", while learning the basic knowledge of mathematics, by telling the past and present lives of currency and the exchange of currencies in various countries, will clarify the role of currency and let students explore and preliminary understanding of Chinese and western culture, and form the correct money values.This is also a beneficial attempt of Qiyuan School to implement the spirit of "double reduction".
