Stock Market Math

What You Need:

  • Stock graphs from (or a newspaper)
  • Paper and pencil

What You Do:

Stock Price:
Total Value of Shares:















  1. Give your child a selection of popular brands from which to choose her stock. For example, Pepsico (PEP), Google (GOOG), Nike (NKE) or Apple (AAPL) are all well-known companies that are publicly traded.
  2. Explain that when a person buys a share of stock in a company, they buy a piece of the company and become a “shareholder.” Each share, or piece, of the company costs money and when the company makes money, so do the shareholders. Next, direct your child to Enter the symbol for the stock (or enter the company’s name to get the symbol). Show her the cost (value) of one share of stock. Next, click on the “intraday” graph which shows the daily activity of the stock and how the value can quickly change. Click on the 5 day, 10 day, monthly, and yearly charts and read the graphs with your child. Note the changes in the stock’s price over the different time periods.
  3. Next, ask your child to become a “mock shareholder”. Ask her how much stock she would like to buy. For example, if she buys 1,000 shares of Pepsico for $68.00 per share, she would calculate the value of her shares by multiplying:

    $68.00 x 1000 = $68,800.00

  4. Have your child make a chart like the one below and follow the stock for a week.
  5. At the end of each day, she should check her stock, fill in the stock price and multiply the price by 1,000 to find the total value of her shares each day.
  6. On Friday, have your child do a final assessment of her stock’s value. Discuss with her what she learned from the activity. Also, ask her what she thinks she should do with her stock – sell, buy or become a “shareholder” in another company!
