Core Skills Analysis
Mathematics
- Interpreted real‑world numerical data by reading stock price tables and calculating daily percentage changes.
- Applied concepts of ratios and proportions to compare stock performance across different companies.
- Used algebraic expressions to model investment growth over time, reinforcing exponential functions and compound interest formulas.
- Analyzed statistical measures such as mean, median, and range of stock returns, meeting CCSS.MATH.CONTENT.6.SP.B.5.
Social Studies (Economics)
- Identified basic market terminology (e.g., ticker symbol, dividend, bullish) linking language to economic concepts.
- Explored cause‑and‑effect relationships by connecting news events to stock price fluctuations.
- Recognized the role of supply and demand in price movements, supporting foundational economic reasoning.

Tips
Extend the stock‑market study by creating a mock portfolio where the student tracks a handful of stocks over a month, then graphing the portfolio's value to visualize trends. Introduce a budgeting exercise that allocates a fictional allowance to different investment categories, reinforcing money management skills. Invite the student to write a short news‑style report on a significant market event, practicing persuasive writing and data citation. Finally, host a family “stock‑day” where each member presents a stock pick and explains the mathematical reasoning behind their choice, turning the lesson into a collaborative debate.
