The process of inquiry develops students' abilities by developing their agency. Recently, Grade4 students have been focusing on the central idea: "Trade occurs in the marketplace in order to meet people's needs.” Conduct an inquiry into “How we organise ourselves", we stimulate students' motivation for inquiry based on their own experiences, interests, working together in small groups, creating experiential situations, grouping and regrouping strategies, and summarising harvests.

In the process of Tuning In, we design learning content that is combined with students' daily life experiences to explain complex theoretical knowledge through concrete real-life examples. Based on their own experiences, students shared their experiences of trading goods in different scenarios such as markets, supermarkets, and night markets.

In the process of Finding Out, we provide personalised learning resources and activity options based on students' interests and abilities. Students are allowed to choose a topic or project they want to explore within a certain range to enhance their initiative and autonomy in learning. According to different preferences, students use iPad to find materials and organise them into courseware to share and display the elements of different trading places.

In the process of Sorting Out, we encourage active communication and collaboration among group members to solve problems together. Students work in small groups to analyse the most expensive, cheapest, most popular, and best-selling products in different product advertisements. Groups are encouraged to share their research process, challenges encountered, and solutions.

In the process of Going Further, we continually group and regroup students based on new interests, ability development, or changes in project needs. Supporting students to deepen their understanding of meaning and acquire skills in different contexts; We support the building of relationships and the common interests of students. Students experienced participating in fruit buying and selling transactions in other grades, simulating venture capital with different partners.

In the process of Making Conclusions, students' reflection and summarisation in the learning process can further stimulate students' desire to explore by reviewing their own learning and inquiry experiences and discovering new learning needs. Students understand business as a dynamic process and write individualised successful investment proposals.
