This activity can be used for Economics, AP Macroeconomics, or any math class.
In this activity, the students will use Consumer Price Index numbers to calculate the change in prices from one year to another year (could be two consecutive years or a range of years). Students do not need any prior knowledge of the price change formula. The formula is given to you on the worksheet. Also, the instruction indicate going to the Bureau of Labor Statistics website to pull the CPI numbers. However, since the numbers are shown incorrectly there (not a great spreadsheet), I included a table (handout) that has all the CPI numbers the students need for this activity. That handout is optional. I like showing students the BLS website so they can see all the CPI numbers going back to 1913. I have also included a key and worked the first problem for you so you can be sure to set the formula up correctly. This would be a great activity for Algebra classes. It would show students a realistic way to use what they are studying in class (why math is important!). Any questions let me know!!!!
