Teaching Materials

• Lesson - Identifying a Percent of Increase or Decrease of Price Lesson (see below for printable lesson).

Lesson Excerpt:

Often in real life, prices change over time.  Sometimes, there can be an increase in a price and sometimes there can be a decrease in a price.

For example, the price of stamps has increased over time.  When we look at what a price of a stamp used to be five years ago and what it is today, we can see a difference in the prices.

Example:                    
In 2000, the price of a stamp in the United States was .39.  In 2010, it was .44 cents.

This reflects an increase in the price of the stamp. We can calculate the percent of the increase too. When the price of something increases over time, we say that this is a percent of increase.

When a price decreases over time, we say that this is a decrease in price.  Let’s look at an example.
