Lesson Plan

If you add Monticello, IL (Illinois) and Greenfield, IN (Indiana) together, you get 107,996. It's a simple matter of adding the ZIP Code for Monticello (61856) to the ZIP Code for Greenfield (46140). 61856 + 46140 = 107,996!

Provide students with copies of the ZIP Code Math work sheet and let them use ZIP Codes to figure sums and differences. (This lesson could be easily adapted for practice in multiplication and division too.) Answers appear in the Assessment section below.

ZIP Code Sources
To complete this activity, students will need access to a ZIP Code directory. Students can get ZIP Codes in any of the following ways:

  • If students have computer access, they can simply type the name of a location into the United States Postal Service City, State, ZIP Code Associations page. Click on the Process button and the ZIP Code quickly appears.
  • Students can use a print version of the USPS ZIP Code directory. Your post office may be able to provide a copy if your school office or library does not keep one on hand.
  • Provide students with a list of the ZIP Codes used in this activity. Click ZIP Code Directory for a printable list of those locations and ZIP Codes.

Extension Activity
Have students use atlases or other resources to plot on a U.S. outline map the locations of all the cities and towns included in the ZIP Code Math problems.

Assessment

Students solve the majority of the problems correctly.
