Core Skills Analysis
Mathematics
The student examined real or simulated stock price tables and calculated the daily and weekly percent changes for each stock. They used the formula for percent change to convert raw price differences into meaningful percentages, reinforcing rational number operations and ratios. Next, the student plotted these percentage changes on a line graph, interpreting slope and trend direction to determine which stocks were rising or falling. By solving linear equations that modeled price movements, they practiced solving for unknown variables and understanding functions.
Social Studies – Financial Literacy
The student explored how the stock market works as a component of the larger economy, identifying basic terms such as ticker symbol, dividend, and market capitalization. They discussed why investors buy and sell stocks, linking personal financial decisions to broader economic concepts like supply, demand, and risk. By comparing the performance of different companies, the student began to recognize how market news and consumer behavior can influence stock values. This activity introduced the idea of long‑term investing versus short‑term speculation, laying a foundation for responsible financial citizenship.
Tips
To deepen understanding, have the student create a mock portfolio and track its value over a month, recording each change in a journal. Follow up with a class debate on ethical investing, encouraging research into companies with sustainable practices. Incorporate a mini‑project where students design their own "stock" for a school‑run product, setting an initial price and explaining the factors that could affect its value. Finally, connect the math to real life by analyzing a current news article about market trends and calculating the implied percentage change.
