While I couldn't locate the official Matthayom 5 Social Studies curriculum document, I did find some relevant information. It appears that Social Studies in Matthayom levels often covers topics such as religion, morality, civics, culture, history, economics, and geography. Specifically for Matthayom 5, some resources mentioned pricing and wages in economic systems as a topic of study. Additional information may be available on Thai educational websites or through direct contact with schools. Some potentially helpful resources include:

• BCCEIP-Mathayom:
• จุฬาติวเตอร์:
• ทรูปลูกปัญญา:
