Lesson 22
The Stock Market
Lesson Narrative
In the previous unit, students worked with percent increase and decrease. In this lesson, students see how signed numbers can be applied to representing changes in the stock market (MP4). This includes representing a decrease (in the price of an individual stock or the value of a stock portfolio) as a negative percentage of the original value.
The names given in the activities are generic, and the data is based on real stock market data from 2016. You may wish to replace them with up to date real companies and data.
